Back again with what seems a very tough diagnosis and could really use some help!
Heres the story.. After posting id replaced the battery and decided to replace starter motor (bench tested OK but thought may be intermittent solenoid or weak motor at best)
The starter motor instantly did the trick fired up like new... for about 10days. Then occasionally it would do nothing on first attempt but start on second. Yesterday morning it wouldnt start at all! BACK TO SQUARE ONE!
Yesterday I checked connections, battery (again even though new) and even cleaned up relays checked for dodgy wires as well as i could.. Then like nothing happened.. it started and drove fine when tested!
This morning DEAD AGAIN! I suspected a intermittent ignition switch (although doesnt explain everything) but have replaced this just now but no joy.
and just to say again this is a No Crank, No start. When I do crank i believe I hear a click from the relays and 'sometimes' a click from the solenoid on start. Not all the time though?!?
Final piece of info I have is that when cranking usually lights on dash illuminate and then go away leaving just the parking brake 'P' and battery light. I noticed yesterday that again, intermittently when attempting to start the battery light went away aswell. Does this mean anything?
It is the intermittent nature of this issue that is the problem. What do I have left to change? I have a few more wild thoughts and would appreciate any ways to test them or other ideas
Ideas- Wire to solenoid from ignition
I believe the terminal is 'terminal 50' when tested we got 12v to this wire but it looked slightly damaged. How do I re terminal this wire with the special VW clip thing. Cost? Shop? Take to Garage?
- Fuse box from Battery+ with 110amp fuse
This fuse had blown before. i believe it goes to alternator. is this a separate issue altogether? (obviously fuse has been replaced now)
Cars brain gone mad? would this prevent starting but then work and not work intermittently?
Dont no what id be looking for or why it would stop it starting..
Sorry for long post but have tried to give as much info as I can.
Thanks in advance
James
