starter issue MY87 5 speed was created by rluvsporsche
Hi All, I've recently replaced my starter (remanufactured) but to my surprise after install it wont crank. I only hear click. I've already check relay by swapping horn relay to starter. I'm missing page 27-16 on my WSM and can not check if wiring installed correctly. I apologize in advance but I keep forgetting and second guessing myself when putting it back together. I wired the 2 large wires together to solenoid. The small single wire buy it self. I took pictures before removing it but it did not come out to good. Can some one give me suggestions what might cause no start issue?

The starter on the 1987 should have three wires on the large post: one very large black wire from the battery, and two medium-sized red wires, one from the alternator, and one to the jump start terminal on the right fender panel. In addition, there should be one smaller yellow wire on the small terminal. This is the trigger wire, that furnishes the power to activate the large solenoid which activates the starter.

When you turn the key to the start position, power goes from Terminal 50 on the ignition switch to Relay XIV, the starter relay. If the starter relay clicks, it is probably OK.

From the starter relay, power goes on a yellow wire from Terminal Q13 (third terminal up on the left side of Plug Q on the bottom of the Central Electric Panel) to Terminal 14 on the 14-pin connector next to the jump start terminal, and from Terminal 14 on a yellow wire to the starter solenoid.

The most common problem is a poor connection at Terminal 14. Disconnect the battery ground strap, then very carefully disassemble and clean the 14-pin connector. Be very careful to avoid letting the wires and connections slip out of the plug pieces. It can get complicated to get them all back into the correct spots!

The wire that you are interested in is the yellow one in the corner.

If this does not help the problem, let us know what you did, and what happened.

Hi Wally you’re absolutely right with wiring on my car. I had the starter lead on the wrong location. After remounting the wire the car stated right up.
Now if I can only figure out my idle and running issue that's plague the car for almost 2 yrs. I'm so frustrated not finding a resolution.
Thank you again for the help

Start a new, properly titled thread, with detailed, verbose descriptions of exactly what the car is doing. Don't make any assumptions, and don't skip anything.
