Starter Connections
Besides the large battery cable positive lead to the starter solenoid- mine has one terminal that has BOTH the battery gauge lead with fuselink and the battery 12v lead to the horn relay with fuse link. (2 connections)
Is this the way the factory installed made the harnesses - with one terminal with both of the fuse links connected to it?
The schematics show the two individual terminals that both each connect to the starter solenoid with the large battery cable (3 connections) instead of what I have (2).
What is correct?
Thanks All! Happy Holidays

What year is your vette? Here is the wire hook up on My 1970 vette. Hope this helps.

I too was curious about the connections, when I pulled my motor out I disconnected them ... but failed to remember 5 months later when I put everything back together. I have 4 wires... Big battery lead, big fusible lead, and 2 smaller leads. I did a little investigating and I should only have 3 leads (77 vette HEI). The extra lead I have no clue what it is, I went ahead and connected it to the S side of the solenoid with the other small lead.

I guess the wiring changed somewhere along the line. I'm retired now and was thinking of moving down to the Phoenix area. How is it durning the summer months? LOL

Summer months are fine down here, I don't even have AC, but I do have this...

On the '69-'74 C3's (which still have points in the ignition system), you should have both the yellow and the dark colored small wires going to the solenoid. And the solenoid should have 4 connections: the main power IN stud, the main power OUT screw mount at the bottom, and the 2 small studs on either side of the cover.
One of those small studs is labeled "S" and is for the wire coming from the ignition switch. The other is the "R" wire which runs to power the coil during the engine start sequence. When the ignition key returns to the "run" position, that "R" wire no longer has power; the coil gets fed via the resistance wire coming from the fuse block connector to the coil terminal. (There should be two wires connected to that coil [power IN] terminal.) The current level in this wire is reduced so that it doesn't burn up the coil from seeing a continuous 12vdc on it.
{Note: Some folks believe that resistance wire is to reduce the voltage to the coil. While that does happen, it is really placed in the wiring because of the current limiting characteristic of that resistance wire.}
