Of course not. You proved that the starter relay works, and that its coil- is already grounded. The key in "crank" applies +12 V to the yellow wire (rel. to BATT-). Measure that is happening. I doubt it since when you apply +12 V w/ a jumper the relay engages. If the yellow wire stays dead, start tracing it from the key thru the firewall to the starter relay to see where you don't get +12 V in "crank".
I guess I am missing something here. I jumper the batt post at the SR to the yellow wire terminal there and it starts at the ign switch. if I do not jumper, I turn ign switch to start and I have NO voltage at the SR yellow wire terminal, and thus none at the sign switch. so how can have a problem at ign switch or yellow wire to feeds it?????
are you saying, jumper the SR full voltage the yellow wire terminal there, and then try to check v. from the ign switch back all the way back down the yellow wire to the SR ?????
