Engine compartment starter
 

I have this yellow wire with a spade terminal in my engine compartment. I gather that is a starter system, so how do I use it?
Connect to a hot lead, ground it , splice in a starter button?
Does it work through the ignition switch or is it independant?

Just near the yellow wire there is a large condensor looking thing with red wires going to it. Just touch the yellow spade to the red wires and the engine will turn over, with or without ignition on. You will have to have ignition on to start the car from there though.

Damon do you have a picture of this? Could it be a condencer/ capacitor mounted on a plate by the regulator? I thought it was an RF filter for the radio and put it aside.

Ron,

The yellow wire is a handy way to crank the engine over when you are working solo. There is a 12 volt post on the left wall 1/3 of the way back. Touching this post with the yellow wire will energize the starter and turn the engine over. If the ignition switch is off the engine will crank as long as you touch the post. If the ignition switch is on, the engine will turn over and start, so be careful.

It can be used when you are doing a compression check, test the fuel pump, etc. It's a built-in added value feature of the 912.

Make sure the car is in neutral. 1st would be okay, but I see some 912 pelican being a darwin award recepient for having the car in neutral, trying to start it, and having it run him over.

A remote starter switch between the yellow wire and post makes this a much easier operation.......

Does anybody know if the same feature (i.e., the same cable) exists in 912E engine compartments?

Thanks.

In a word, no.

Ok, understood. But how can I, e.g., check the compression? Is there some recommendation how to accomplish the same thing for 912E's?

Thanks

912E:
If you have a little time & feel like crawling around try this, but be absolutely sure to disconnect your battery first - as you know, the 912E has some pretty sensitive electronics controlling the FI.

1. Open up the rear fuse/relay cover on the driver's side, engine compartment. You're looking for the so-called "double relay" which basically tells most of the engine electronics that the engine is cranking. This relay is rectangular and sits horizontally against the fender wall between the voltage stabilizer and the FI resistance box. It has two, separate multi-wire connectors plugging into it from the bottom. On these connectors, you're looking for a solid yellow wire. If you find it, first mark the connector's orientation and remove it from the relay. With battery disconnected, run a continuity test from this yellow wire to the wire on the solenoid. If it is, infact the wire you're looking for, this is the wire that goes back to the ignition switch and operates the starter on momentary contact (cranking.) Touching this wire to power should crank the motor. If everything is good to this point, I'd suggest a simple remote switch which connects to the removed connector's yellow wire and a 12v source (I'm going from memory, but one of the rear fuses might be always hot.)
Good luck & remeber to disconnect the battery while you're testing.
Bill.
