Has anyone ever had a failed module come back to life? I have not.

Bob,
I hate to tell you this but I have had the exact same Mallory distributor
failure in two differnt Panteras that I have owned. Whatever they say about
the
wires I would not drive across the street with a Mallory distributor UNLESS
I
had a spare module in the glove box.
Just my experience.

Hello Friends ,
I thought compelled to tell the group what transpired over this past
weekend with the Gumball Pantera .
Just before the Gumball in May of 2009 I made the following improvements
in the engine compartment.
New Spark Plug Wires MSD PART #31199
NEW HOLLEY 650 DP
NEW MALLORY COIL
NEW MALLORY BALLAST RESISTER
NEW ROTOR AND CAP FOR MY MALLORY UNILITE DISTRIBUTOR
NEW AUTOLITE SPARK PLUGS PLUGS
I set out this past Sunday for a 2.5 Hr ride to Lime Rock Raceway in
Connecticut. The car was humming like it usually does for the first 100
miles
and then while moving at about 60 mph the car shut off and I rolled into
the
nearby gas station. I thought it was a stuck float in my holley 650 so i
tapped the adjusting screw and the car started right up and then shut off.
I removed the float adjusting rod and put all back together. Still the car
would not run. I decided to try and limp to Lime Rock since there were
mechanics on hand . I got 1/2 mile and the car shut off again.
I called a flat bed and was taken to the track . Mechanics at the track
replaced the coil and the ballast resister .
The car fired right up and I thought this was the end to my nightmare. I
also noticed that the fuel pressure was very high at 9.5 to 10.The
mechanics said that the carb could handle that pressure..So I believed .
At 4:30 I got back into my car followed by a 1973 Pantera Buddy from the
Long Island Pantera Club.
One hour later the car was down for the count again. Thinking this was a
dirt in the carb fuel issue I removed the carb turned it over and dumped out
all the fuel in the carb. She started up, but this time I noticed that the
tachometer was flying all over the place. Now I knew this was not a fuel
issue but something wrong in the ignition/electrical system . I was stuck
in
the middle of nowhere .
After waiting 4 1/2 hrs for a flatbed to arrive we loaded the car once
again and I took the car to Danbury CT. to a friend that loves to fix
electrical issues.
The first thing my friend said after reading the Mallory Unilite
instruction manual was WRONG WIRES ON THE CAR !
He said I will bet the Module in the mallory distributor is fried .
I spoke with Mallory today and confirmed that the MSD wires used are in
fact the culprit. Over time the wires will break down the Distributor module
and it will eventually cease to work.
I am telling you all this because if anyone is running a similar setup,GET
RID OF THE WIRES AT ONCE.
Mallory recommended the foilowing :
Unilite Distributor with #30450 COIL
Carbon or Graphite Core Wire ONLY (SIDEWINDER PART # 931)
If the system is reading 1.4 ohms or less you need the ballast resister .If
above 1.4 ohms there is no need for the ballast resister.
Now I also spoke to Holley and they said the fuel pump pressure is way
to high and that the fuel pump should be replaced as well with Holley part
#
12-854. This mechanical pump will be 80 gph compared to the 30gph that I
had on the car . The fuel pressure will only put out a max of 7.5. Fuel
pressure of 10 will blow the seals of the carb.
Any suggestions or comments would be greatly appreciated.
Best Regards,
Bob Levitt
