Electrical Component Checkup for Nonstarter
The real test is with a VOM (volt meter) with alligator clips on the leads. You need to have over 8 volts for the starter to function; preferably well over 8, like 10 or 11. This is with the motor activated.
Set the meter in the windshield, propping it with a wiper blade, such that you can read it from the driver's seat. With each test connection, key the starter and read the voltage. We'll move the probes around to isolate the bad connection/component.
Inspect the two positive cables and clean everything. A common failure point is the main power distribution junction block. It's a bolt lug with multiple wires on it beside the battery. Hard to test this particular area as there are several wires stacked... and a bad connection can happen any where in the stack.
If the test proves it's either the solenoid or motor itself, try giving it a good thump.
Good luck, again. ** Two wrongs don't make a right. Try three. **
I don't remember the full extent of the problem but heres some ideas (read random thoughts :-) )
I am going to have to speak generically, as I am not familiar with the s2 (I own s3 xj6) and my wiring diagrams only go back to 81.
If problem is persistant. Actually, I mean not intermittant.:
If problem is intermittant. The same procedure should hold true. You will just have to keep turning key until starter doesn't spin and watch the meter or light at that time.
I liken the flow of electricity through wires to the flow of water through hoses. It goes in one end and comes out the other. If it isn't coming out, either it's not going in, or the hose is plugged (broken wire or resistance to high). Basically the starter solenoid is like a valve being turned on by the key switch (another valve).
Tracing electricity through a circuit is not difficult. It just NEEDS to be done systematically. Start at one end of circuit (it doesn't matter which) and move progressively to the other end, checking both ends of each wire. At some point you will lose power. Then you know the component that has failed. Not difficult, just time consuming.
I would suggest starting the tracing over. Assume NOTHING. Work deliberately from one end to the other as I have described. I know that this sounds as if you are rehashing what you have already done but the answer has to be there. But it cannot be found by jumping from one spot to another. I once pulled my hair out trying to figure out a no spark problem. Didn't follow this advice and assumed some things that were wrong. As it turns out, while I was doing something else I had a friend make a new wiring harness on top of the engine to replce some wires with cracked insulation. We kept both ends of the original wires as they were still in good shape. This way when the new harness was all taped up, the original wire colors were still exposed so harness could still be traced with factory diagram if neceassy. Anyway, the positive and negative coil leads got crossed in the new harness. After hours of frustration, I cut open the harness out of couriosity and there it was! Threw a test meter on it and BAM it showed right up.
Thats enough rambling for now. I hope I didn't scare or confuse you. It really is to bad to do. Electricity used to scare and CONFUSE me until I thought about the hose and water theory, then it made more sense.
Best of luck. If I can be of further help let me know. (I am ASSUMING that this was a help :-) )
