Wiring diagrams

Post by Gr8Gary »

Hi all, this is my first go around with a roadster. Have done several Z cars and there are sites where you can get into factory service manuals online. Does anybody have these resources or can point me in the direction of wiring diagrams. I am working on a 69 2000. Just picked it up and recently got her running but alternator is not charging, need wiring diagrams. Thanks for your help!

Thank you Matt and Curtis, I grew up in Williamsville, graduated from Williamsville South in 79! Small world I tested all wires and they ohm out properly, I have an extra white wire from alternator, not sure that’s the correct one. I tried a known good voltage regulator and still no charge

The tech wiki has several different shop manuals posted as well, as long as a wealth of forum member supplied tips tricks and time savers. It'll be well worth your time to look through the whole thing to have an idea of the resources at your fingertips.

Uh oh, sounds like someone has rewired. You ahould havw one large white and possibly a small white. Since it is 69 you may only have the other small wires. Yellow, black, white with black stripe. And black with white stripe.

Is the alternator still on the driver's side?

I had an error in my drawing, I left off a wire. I fixed it and put up the new one.

Beautiful Z, Gary. And the roadster looks like it’ll be a fine project also! Where are you now, if not in frigid WNY?

It doesn’t look like the car is been rewired, there are three wires coming out of the harness yellow, White with black, and black, A large yellow wire to the positive post on the alternator in a ground wire for the alternator.. Alternator has the same colors plus the addition of one white wire which the spade was pulled out of the plug for some reason. May have been pulled out because previous owner had same problem? Don’t know. Alternator still on Driver side. This car was put together and never driven. Do they make two different alternators for the Roadster? Wiggling the wires around earlier today found the yellow wire broke out of the connector on the harness side. Think I’ve got another connector that I can replace it with. By the way not far from Williamsville now I moved to Houston, then to Tennessee, now in Indiana. Getting closer to the frigid north! LOL

For it to work properly you need all the wires hooked up including the small white one at the VR.

You can get all the stuff you need to repair the connectors at Vintage Connections/Sparck Moto.

Yes, under the exhaust manifold, what a lovely place to put an alternator. And of course there is the added benefit of having the intake on the same side too.

Hi Matt, looks like you have three wires coming out of your harness also to the alternator. Soldered a new connector at alternator because connections looked horrible and yellow wire snapped. Everything is connected properly at the voltage regulator. Got power at white wire on voltage regulator and big yellow wire at alt. At this point I’m thinking it may be a bad alternator, any way to test it on car? It’s a real pain in the ass to R&R the damn thing where they have it located. By the way, she runs and drives has all five gears and lots of power. Put about 5 miles on this afternoon. Obnoxiously loud, need to get a better muffler, LOL.
