1976. V8 Conversion, but the starter wiring is (near) stock.
It did this once in the past, and has done it again. Turn the key to the start position, hear a relay click under the dash, but the starter doesn't engage and spin. If I jump the big cable at the starter to the terminal on the solenoid that the brown wire is connected to, the starter spins and starts the car. The last time it healed itself after the car sat for a couple of hours. It hasn't been that long now, but I need to find what the problem is and fix it. I have jumpered around the original seat belt interconnect. Ideas? (BTW, electricity is magic to me so keep it simple (IMG:style_emoticons/default/smile.gif) ) |

Success!
I first disconnected the rear connector on the relay panel going after Dominic's fix. With the connector disconnected, I put 12V to the female pin on the connector that is the starter trigger. Starter spun. I reconnected that connector and disconnected the front connector. I put 12V to the male pin on the relay panel where the trigger came in to the panel and the starter spun. I then knew power was not getting to the relay panel, but if it did, the starter would work. I figured the next connector upstream is the one where the yellow wire in from the key switch ties to the yellow/red wire out to the relay panel. (IMG:http://www.914world.com/bbs2/uploads/post-104-1418650535.jpg) With the key turned to the "start" position I had 12V on the yellow wire coming in from the key switch. Since I don't think there is another connector on the yellow/red wire before the relay panel, it had to be a fuzzy connection between the two (at least I hoped it was (IMG:style_emoticons/default/smile.gif) ). I replaced the connector with a crimped splice. That did it. A big thanks to everyone, and especially Clay for the solution. |
