Hi All,
Well, I got out the multimeter...
Juice on the large red wire terminal on the fire wall.
12v at the coil. But no spark at the plugs.
No fuel pump either.
12v at the key switch. It seems to be working.
I both checked the voltage at #4 relay slot, and replaced the switch, as well.
I seem to have power to the two relays in the black box, drivers side, engine
compartment.
Next, those relays? I put 12v to the switch sides, on the relays, #85 & 86, I
think.
they do (sound) like they are working, but how do I know for sure?
Can they be bought at flaps?
Or just the VW places?
Thanks to everyone for their help!
I've studied the manual, & I just get more confused?
But your systematic approach is helping immensely!
thanks again,
John C

91 CRANKER, BUT NO STARTER....YET! :)
