I think I've lost it. 12/24 Volt Conversion.
Since I love electrical work and making Frankenstein , I've decided to convert my truck to a 12/24V system. The hub of the entire system is going to be the 200 amp 12/24V alternator from a HMMWV.
I want to put the starter and grid heaters on the 24V circuit along with a few choice accessories......
I know I can rebuild the starter with 24V parts, so that's no problem. My question is, if I use 24V relays, can I run 24V to the grid heaters? My instinct is telling me yes since they will be pulling almost 1/2 the amps they did on 12V, but I know there is a possibility something in the system (like the PCM) can keep them on for too long and possibly damage them. If that is the case, I'd just take the PCM out of it and run a separate switch to trigger the relays.
So, anyone a grid heater expert?
