Hi all.

This is for Motronic on my 2.0 Jetta powered Vanagon. I am chasing
down a consistent hot start issue. (fuel pressure is ok) I doubt the
hall on distributor is the issue but I am curious of the wiring to it.
I had to repair and modify the wiring harness for this engine swap.

Bentley shows a difference in the + reference wiring to the hall. Most
model years receive ECU supplied +  (5 Volts?), others receive battery
voltage. My Jetta Bentley specifies a minimum 4 Volts at distributor
hall connector.

I can supply images of the diagrams if needed.

I will re-measure this, but would connecting the hall to 12 Volts
shorten the life of the hall, or would it cause the hall to send too
high a voltage square wave to the ECU? If so, is this damaging the
ECU?

Thanks,

Neil.
