[DML] Re: Starter circuit theory?

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

If you believe the schematic circuit #1 should not have anything to do
with the starter circuit. The power for the starter circuit is
actually unfused, coming directly off the ignition switch (not great
but intermittant anyway) The starter circuit is powered only when the
ignition switch is in the "start" position. If it came from somewhere
else it would be powered constantly. You also said the start inhibit
relay is clicking even with fuse 1 out. If the relay clicks then it
should be powering the starter solenoid. You should pull fuse #1, put
a test light on the start inhibit relay and see why you don't get
power to the starter. This could be an error in the schematic or it
could be a wiring error in your car. The #1 circuit is green and the
starter circuit is white/red. Another possability is some kind of
weird back-feed due to a bad or missing ground. If you have a 5-speed
the start inhibit relay doesn't really do much anyway, it is always
"on" unlike the automatic. Refer to M18:01 and M:18:02 and Main wiring
circuit M:18:23 Actually I already see an inconsistancy between
M:18:01 and the Main wiring circuit schematic. Follow "N" in M:18:01
and then look for it in the main wiring circuit. It does not appear on
#105. Maybe this is really coming from #1? Further investigation is
necessary.
