Relay Activated Battery Cut-off switch
I have a quick disconnect on the side pole mounts of the Optima battery. It looks clean and functions perfectly but you have to open the front hood to operate it. Brad Freeman's car has a manual cut-off switch installed that is mounted through the trunk on the side of the battery that you can operate by reaching behind the glovebox from the passenger seat and turning it on or off. Has anybody added a massively heavy duty relay that can be triggered by a switch in the cabin to disconnect the battery? If it is a standard relay, it would only pull current when activated, so that would not drain the battery. Could it damage anything if the battery were accidentally isolated while the car is running (i.e. MSD ignition or fuel injection computer)? If anybody did this, what relay could you use?.

I don't have direct experience, but from the application I would think a latching relay would be desired. They use momentary pulses to open and close. My first google for such got several hits (I don't have time now to research) http://www.pdxrv.com/catalog/i915.html Joe -----Original Message----- From: DeTomaso [mailto:detomaso-bounces@server.detomasolist.com] On Behalf Of Rob Dumoulin Sent: Friday, July 15, 2016 8:55 AM To: Pantera Mail List Subject: [DeTomaso] Relay Activated Battery Cut-off switch I have a quick disconnect on the side pole mounts of the Optima battery.

I have a latching relay on all my cars. They are great. I guess a small push button switch somewhere in the cabin and shut the car off whenever I park it. I purchased all mine from summit. I think they are Painless brand but I'm not sure. I also do not have an MSD or fuel injection controller so not sure how that would work. (Although my Pantera will have both of those) Lynn Sent from my mobile device

I would also be interested in comments about the second part of Rob's question. For my disconnect switches, I have installed them on the battery ground with the intent to isolated the battery from draining. However this would allow the alternator to keep the engine running when disconnected. I have worried that the alternator's voltage regulator could swing without the battery capacitance. I would THINK if the intent were a energy isolation to kill the car/engine, the switch should be on the positive feed (with the alternator still connected to the battery).

Hi Joe, The disconnect switch on the (+) or (-) cable does the same thing, it isolates the battery from the car. I am a bit confused by you wanting to disconnect the battery but yet still keep the car running. What is the reason you want to do something like this? With all the electronics in cars, even ours, this is not something you want to do!

I agree, it is not something I would intentionally do. Given I have "at the battery" knife switches, It is sort of intuitive to cut the car off, open the hood and disconnect battery. However, many decades ago, I did install a turn switch in the console of the TR6. I was initially surprised when I give it a turn and the car continued to run (including all lights etc). When Ron asked, I thought how are those electrical kill switches wired in race cars? Do they kill the ignition or do you assume the engine died in the wreck and just isolate battery? Thus there could be two sort of different objectives with the battery switch. If you used a single contact to kill the battery and alternator, the alternator diodes could drain a battery in storage.

Race car kill switches generally have two circuits. A heavy duty one for the battery and a lighter duty one for the ignition. You want everything off should there be a problem. Most of what you see on the street is to isolate the battery when the car is parked. Larry - Cleveland -----Original Message----- From: Joseph F.

There are battery cut-off switches with separate low current switches that can kill ignition too, which would stop the car. I guess it could be wired to kill the field winding in the alternator, which would stop it from generating any current.

SCCA and other competition sanctioning bodies require a MANUAL (total) battery disconnect for certain classes of competition cars. As with electric heater-valve cut-offs in Panteras, an electric device probably is not a competition-legal device for sanctioned events. Reason for electric heater valve cut-offs being disallowed is, the Tech inspectors do not get into verifying that an electrical switch is installed correctly and works dependably, so they are not allowed thru Tech whether or not you have success with it. This likely reduces the market for such a device, I suspect.. FWIW- J Deryke -----Original Message----- From: Joseph F.
