Working on my Starter, still not working.  But I do get power to the block side terminal when the key is turned to start.Smile

I think I fried something else.  Whereas I used to get all the usual dash light when I turned on the key, plus the key in buzzer because the door was open, now only the sea tbelt and park brake lights go on.

There is no power to the horn relay where so many wire get a hot tap.

No fuses look bad visually, any guesses on where to start?  I'm a fusible link newbie.

The wiring diagram does show another wire(red) attached to the main battery cable terminal on the solenoid, and that wire goes up to the horn relay/junction. It does NOT show it to have a fuse link in it, tho. In fact, the diagram doesn't show to have ANY fuse links, but I think there should be some in the system. They are sometimes right by the horn relay...easier to get to.



You should have battery voltage on BOTH sides of the links...if you have voltage only on one side, the link(s) is bad.

Thanks again.  Looking at the wiring diagram, from the solenoid,  I see a Red wire to the Horn relay and a BIG black wire to the battery, and this is how power gets to the horn relay.  I'll check these two for power, continuity in the morning.  At least I have a direction to go.  me guesses we connected something wrong, and/or fried something.

It stopped raining today so I got out to the car again.  As suspected, the wire from the Horn Relay to the Starter Solenoid is not connected.  Plus, I can't even find the battery cable.  It should be a BIG wire, right?  I'll get out there again tomorrow.  I'm trying to label all the wires in the rat's nest.  I'm checking continuity from the starter end to the suspected other end to confirm.  I'm writing this down in case someone else needs to rewire their starter someday.

 Battery cable will be the same size at the starter as it is at the battery, so yes, it's pretty good sized.....they usually don't get lost among all the other wires in the starter area.LOL
Assuming your car still has the insulation on the trans tunnel, the battery/starter cable will run alongside the trans, underneath the insulation, and come out just behind the bellhousing in the starter area. Large eyelet terminal on it that goes to the large stud terminal on the starter solenoid, along with the other wire you found that goes to the horn relay. Thumbs Up

Found it. Smile For your amusement, here's my wiring.  Header is dropped to allow R/R of starter.  Two wires for the remaining solenoid connections are green and black; supposed to be yellow and purple. There is an extra green wire too, I guess I'll find out where is goes when something doesn't work.

OK, starter is wired.  But I still have no dash lights except the courtesy lights and seat belt lights.

We have juice at the horn relay and all the fuses checked out OK.

Any ideas to check?  Haven't checked fusible links yet, which one is the likely culprit?  Could a busted ignition lock cause this?

Thanks,
Jim

eldredjames - I'm going to attempt to attach the wiring diagram for your model vette. Hopfully you can download it and blow it up to start tracing the wires that are being effected by your lack of power or lack of ground. It is a process of elimination. Good Luck.

Jim...do the head/tail lights work?

Thanks  Tomtall.  I've already got two wiring diagrams, but this is a new prospective. Never hurts to have more documentation.

AA I'll check the lights out tomorrow. :-)
