Hi guys, Just got home from a terrific weekend in the Sierra foothills; 24 Panteras (of the 36 scheduled) took part in the Niello concours at Serrano. It heaved down with rain for a very brief period, but that rain then turned to snow which kept the large Reno/Tahoe contingent from braving the summit. Still, a great time was had by all who attended, and we drove home in splendid sunshine. We were driving in Lori's Pantera, which has a flat firewall kit and uses a GM alternator with built-in regulator. She drove the car to Vegas this spring, and the alternator failed while we were there. At first it started acting erratic, with the amp needle bouncing around, and then finally it quit and just showed a partial discharge. Testing at the battery revealed it was doing nothing at that point. We replaced it with another one, which did exactly the same thing and failed about 50 miles from home. We replaced THAT one, and the third one has worked fine until today. But it probably only has about 250 miles on it or so. On the way home, once again, I noticed the ammeter needle behaving erratically, then it quit and showed partial discharge for many miles, then briefly came back to life and showed a very strong charge (since we had been running on battery power for awhile), then discharged again. Methinks the problem is not simply that alternators are failing, but rather that there is some sort of fault in the electrical system. As electrons are far from my strong suit, I hesitate to start diving it to it blindly. What say all of you? FWIW we've got a spare alternator we will be installing tomorrow, which almost assuredly will work just fine...for awhile anyway????

Is it wired so that the indicator light in the speedo works? Are you using the external cooling fan on the alternator?

Good morning Mike, High ohm engine ground strap connections will cause spastic and damaging alternator function. If it charges now then use a hand held load meter; -1-set idle-hold at 1,500 and note volts + amps at both battery post at no load, now load the meter and note, -2-Then from batt positive post to closest frame ground, loading and noting again, a six second 100 amp load will smoke out the weak connection, -3-Then from alternator output post to engine block, repeat above no and load test, -4-repeat from alt output to frame ground, repeat above no and load test, -5-now place load meter or test light from engine to frame ground and find voltage or light, 1 and 3 will be closely identical, though 3 slightly less due to wire distance ohm reduction, reference values that you can base the alt function and amp meter realities. 2 and 4 will help you find electrical resistance. If all above 8 test give pretty much same values within a .3 volt and 5 amp variance then you need to find flaw elsewhere. Sometimes a 10 second 100 amp load test at 3,000 may break your hidden problem, try and see if above 8 don't point to issue. If it does not charge then use a large battery charger and load both battery post then repeat and charge alt stud and engine ground, you may find resistance. Also an extra large woven ground strap never hurts! 33 years ago the Baton Rouge Volvo dealer sold me 6 defective alternators in a row for the same customer. I was the largest Volvo repair shop in town and also was paid my said dealer to do warranty work for them as they were overloaded. The 7th one worked, the owner was scamming his dealership and was putting new-defective-warrantied alternators back in stock so to make more money to finance his hydroplane racing. Of course I was the largest buyer of Volvo parts so I got stung and customer was pissed beyond belief. Year or so later when owner was busted, jailed and dealer closed, his son brought me as a guilt gift a new Volvo cylinder head in crate and other parts so to make amends. Poo-poo occurs. Back in March prepping for Amelia, I noticed where my Mangusta had electrical burning marks on the alloy around the large bell housing bolt washer interfaces, WTF???, we found the bolts not to be as tight as they should have been. So my alternator engine ground was trying and having a difficult time getting back to the true body-battery ground and left burning-jumping marks on the bell housing. Now all is fine and battery cable temps are cooler.

Mike, I hate chasing these type of electrical problems, but here's some thoughts; i) Battery going bad (how old is it?), requiring the alternator to have to constantly charge ii) Some alternator re builders are notorious for units failing, over a 50% failure rate is not uncommon. I had a similar issue with my GT40; on the third alternator we switched to a higher amp 'new' unit and never had a problem since. iii) It could also be an intermittent short or bad ground Julian ________________________________ From: DeTomaso <detomaso-bounces@server.detomasolist.com> on behalf of Mike Drew via DeTomaso <detomaso@server.detomasolist.com> Sent: Sunday, October 2, 2016 9:11 PM To: detomaso@server.detomasolist.com Subject: [DeTomaso] Alternator blues....

Hey Mike, After we left you yesterday afternoon, The trip back over the Sierra¹s last night was horrific. Rain started just above Placerville as we hydroplaned many times the rain was so heavy. The snow started below 6000 feet causing white out conditions several times. At the top of Echo summit there was a Bad Head On collision that closed the highway in both directions for quite a while. Certainly no place for Pantera¹s yesterday evening. Apparently The Reno Tahoe Pantera¹s stayed in place for good reasons.

Hey Mike, After we left you yesterday afternoon, The trip back over the Sierra^1s last night was horrific. Rain started just above Placerville as we hydroplaned many times the rain was so heavy. The snow started below 6000 feet causing white out conditions several times. At the top of Echo summit there was a Bad Head On collision that closed the highway in both directions for quite a while. Certainly no place for Pantera^1s yesterday evening. Apparently The Reno Tahoe Pantera^1s stayed in place for good reasons.

Hi guys, Just got home from a terrific weekend in the Sierra foothills; 24 Panteras (of the 36 scheduled) took part in the Niello concours at Serrano. It heaved down with rain for a very brief period, but that rain then turned to snow which kept the large Reno/Tahoe contingent from braving the summit. Still, a great time was had by all who attended, and we drove home in splendid sunshine. We were driving in Lori's Pantera, which has a flat firewall kit and uses a GM alternator with built-in regulator. She drove the car to Vegas this spring, and the alternator failed while we were there. At first it started acting erratic, with the amp needle bouncing around, and then finally it quit and just showed a partial discharge. Testing at the battery revealed it was doing nothing at that point. We replaced it with another one, which did exactly the same thing and failed about 50 miles from home. We replaced THAT one, and the third one has worked fine until today. But it probably only has about 250 miles on it or so. On the way home, once again, I noticed the ammeter needle behaving erratically, then it quit and showed partial discharge for many miles, then briefly came back to life and showed a very strong charge (since we had been running on battery power for awhile), then discharged again. Methinks the problem is not simply that alternators are failing, but rather that there is some sort of fault in the electrical system. As electrons are far from my strong suit, I hesitate to start diving it to it blindly. What say all of you? FWIW we've got a spare alternator we will be installing tomorrow, which almost assuredly will work just fine...for awhile anyway???? Mike Ditto. I put in 2 rebuilt units and they both failed.

All, Further to my original inquiry, I failed to mention that this is a GM alternator with built-in regulator, running in the stock three-wire configuration. Normally it works normally--shows a somewhat strong charge for a short time after engine start, coming back down to slight charge when battery is 'full' again, with slight discharge at idle when fans, lights etc are on. When it starts acting up, initially the needle bounces erratically over a small range between slight charge and slight discharge. After a few minutes of that, it goes into greater discharge mode as it quits completely. Mike Sent from my iPhone On Oct 3, 2016, at 8:15, "Himes, Terry (397C)" <terry.himes@jpl.nasa.gov> wrote:

My first suspect would be HEAT. Google shows two different external fans, one being more air flow than other. At idle with lights on, slight discharge; the alternator would be getting its hottest due to high current/low speed with the least amount of speed for the cooling fan. Putting a temporary temperature gauge on the housing would let you know, my first google for acceptable temperature has not provided a value, BUT several mentions of temperature, low speed high current causing rapid failures. IF (hopefully WHEN) I get a running Pantera, looking into providing cooler air to the alternator will be something I hope I remember, mayby some type of shielding/ducting AND just because I think it is needed, a grounding strap from alternator to chassis wouldn't hurt. When I get time I'll search more on alternator temperature range.

The GM 1-wire on my XKE died after about 6 months, replaced it and been fine since. Also have one on our Pantera, with about 5,000 miles, everything fine so far. I will comment that, given the lack of air flow when the car is sitting still, I suspect my added cooling fan might help a little, but heck, the alternator is not right above the exhaust manifold - would not think it would get that warm unless it has too small a built-in fan... As I recall there were two options when I bought our 1 wire from Napa - one with a fan that looked a lot nicer.

Check the fat wire from B+ (or what it is called on the alt) to the ammeter. If there is a marginal connection there the voltage can fluctuate wildly and possibly kill semiconductors in the alt.

I didn't find any detail info, just one reference to where regulator switches off above 320F. as for "cooking" the wiring's insulation,causing failure, all I can go by is normal motor/generator insulation classes, the cheapest should not exceed 220F and the best 320F -----Original Message----- From: DeTomaso [mailto:detomaso-bounces@server.detomasolist.com] On Behalf Of Joseph F.

Quick thoughts. I recently looked at an ammeter in a Pantera that was pegged on full charge... even when the battery was disconnected. um..... So I took the dash apart and found the terminals on the ammeter were kind of fried and all the ring terminals were black from oxidation. Short story, we put all terminals on one post and bypassed the ammeter. What's my point. I know Mike has probably got a recommended bypass on his ammeter, but maybe it's worth pulling the dash, removing all the connections, polishing them up and putting it back together. At least that would eliminate the gauge and it's connections. Because David has a good point.

OK - here’s a bit of a co-incidence - My father wanted to buy a Porsche Super-90 in 1961 at Neillo Porsche - at that time they had one business only - the Porsche dealership on Fulton Ave. in Sacto.. BUT - Mr. Neillo wanted the car also - a powder blue couple with red leather. So the battle began with my father arguing he had cash in his pocket and the car was on the showroom floor - so it was “for sale”. Neillo won - so my father bought a pearl white Super - removable hadrtop - red leather. But he loved the Super-90 (red line-6500). I was in high school with Rick and Roger Neillo and almost wound up in a fist fight. We were in a German language class when it all went down - Good story. I see the family has expanded their business - more headaches. I am now the longest standing member of the Porsche Club of America( 61 years) and the only remaining Charter member - it began in 1955. I should go pull some rank on the Neillos for old times sake. Anyway - I thought I recognized the name. Jack
