OK following the last couple posts a few days ago.
I would like to tackle one problem at a time. Putting aside the fact that the starter refuses to turn when wired directly to another running car, I would like to tackle the following problem:
The small starter wire (blue yellow as I recall) provides +12v with KEY in position II (before actually cranking). This is an obvious issue.
Here is some history: I had installed 6 months ago a remote starter. The job was neat and clean and has worked perfectly. The car has no history of starter/starting issues before or after that mod. Everything otherwise is original and unbutchered.
Firstly I suspected the remote starter relay box to have a relay stuck. I pulled the harness off the box and measure the voltage at connection 50 upstream at the ignition switch, key position II and STILL get +12v at the ignition switch. Haynes diagram shows also connection 50 as the starter signal which confirms my wiring and test.
Hence, no issues with remote starter relay box.
Why does the ignition switch give +12v to starter with key position II? (BTW also maintains +12v in position III) Putting aside the possibility of the switch being defective for now, I would like to make some easier tests first. I noticed that haynes shows the signal also going to the "control unit" (BL/Y).
- Is this referring to the 561 (which I have) or to the other unit (against the firewall beside the audio amp - what is that anyway?).
- Is it possible for the control unit to be feeding back the +12v? computers are original on this car.
- How do I remove the harness connector on the 561? Top screw off first?
(I'd like to remove it to isolate only the ignition switch with battery circuit to confirm what the cause is...)
BTW throughout these tests the wire was pulled off the starter solenoid.
Any other thoughts? I feel like I am losing it, this car has beem running perfect for +100K and 3 years now.
Thanks in advance,
