Stay alive while cranking
There is a lot of discussion over "tank" circuits and other ways to keep your car-pc alive while cranking
When testing my computer system i hooked the invertor directly to the battery, without using a relay or anything, i noticed the computer stayed alive whilst cranking
The current setup has a relay, controlled by the ACC+ line to trigger it. As the car cuts out the ACC while cranking, the invertor shuts off, killing the computer power.
As the invertor survived the "crank" when i tested it, the cutout isn't because of the voltage draw of the starter.
Logically couldn't i put a smallish capacitor on the ACC+ line (used as the relay trigger) to keep voltage supplied to the relay whilst cranking? Would this work? would there be any possible harm to anything if it tested this?
