Re: [DML] Starter circuit theory?

["Jake" <jkampho@xxxxxxxx>]

Hi Dave,

Funny you should mention this... I had a similar problem just today.  I
decided to unhook my door lock module at the circuit breaker (brown wire)
and was surprised to find that my car wouldn't start after I unhooked it.
The symptom was the same: my start inhibit relay would click, but no start.
Considering the only item that these circuits have in common is the inertia
switch, it had me confused.  I should also note the car would run fine when
I roll-started it.

After studying the wiring diagram, I noticed that my car (early, 1063) had
the starter update done, but the "new" wire that is recommended by the
service bulletin had been rather lazily run to the door lock circuit
breaker!  So no power to the door locks meant no power to the starter.  I
found this strange on my seemingly otherwise unhacked car.  After putting
the wire on the correct breaker, the car fired right up, smooth as silk.

I'm assuming the car you're working on is not your late(r) 81?  If not, it's
something to think about.  I guess you never know what might of happened to
the wiring in the last 23 years...

For me and 1063,
Jake Kamphoefner
