Thread: Bone head mistake - POWER DOORS

Tweet

My power doors have manual latches, but they're inside the car. Mine work with an Auto Loc remote, but I also have a separate circuit that can provide power to the latches, from outside the car. I use a separate circuit, on a different breaker, for added reliability.

I've got two stainless steel allen head bolts in the fender well that will conduct power to the latch if a piece of metal contacts both bolts at the same time. One bolt head is hot at all times and the other is connected to the solenoid. Applying +12V to the correct bolt head, from outside the car would also activate the latch.

I've got out of the car, left the key in the ignition or the engine running and shut the door. The emergency circuit has been used several times already.

Having a fiberglass body also makes it easier to install the circuit, since the bolts through the body won't touch a ground source.
