And now my car won't start...

Hi All,

the last test doesn't give anyone a clue what the problem could be? I (but you will already have guessed) have abolutely no idea...

Thanks!
 
Disconnect both small wires, see which one becomes live when the key is in the "start" position, then hotwire the small terminals in turn to see which one fires up the solenoid, then connect the "lived" up wire to the terminal that operates the solenoid. (And the other one to the other terminal)
 
Hi Harvey,

unfortunately i again don't understand exactly what you suggest: if i remove the wires (white/yellow and blue), how do i see which one becomes live when key is in start? With test light again, connecting through the ligt the spade and the earth on the solenoid (no 3 on my photograph earlier?).
And with the hotwiring and then connecting the live wire to the terminal that operates the solenoid: if i understand you right: do you suspect the small wires are connected in the wrong way?

With the test light connected between the end of the wire and earth.

The large terminal (3) shoul;d be permanent 12v

I think that may be the case.
 
Hey Harvey,

i'll check this for sure, but what is weird: the car started perfectly for the fist few months, and then stopped gradually over the last week...
More tomorrow. ;)
 
Problems often appear over a period of time.

Well I hope you sort it by tomorrow, because I can't take much more of this. The thread is 3 pages and 45 postings long, and so far all that has been asked is you test the supply to two wires, and you haven't managed to even do that yet. If this gets more involved I won't live long enough to be able to sort it.
 
Hi Harvey,

i'm sorry for having not much of an idea what i'm doing, my expertise lies elsewhere unfortunately.
I've read the posts on this forum concerning this topic, but didn't get very far... The step-by-step is annoying i'm sure, but i do need it.

I'll check the supply to the wires and hope to not bother you anymore!
 
If you like the idea of playing with old cars, especially the electrical side of them, a multimeter is pretty much essential, and very useful.
 
So: i did. Interesting purchase!

With help of your suggestions and the interwebs have learned the following:
- battery is okay: 12,4V
- large terminal on solenoid is permanent 12,4 V
- engine earth is okay: 0V
- white/yellow connector on the solenoid is the one that becomes live. Only: between battery-earth and white/yellow connector only 8,9V when ignition is turned completely. But also: the blue one also does read a bit: 4,7V with ignition turned.
- startermotor-earth reads 0,6V when connected to battery-earth and ignition turned completely: should be 0 or close to 0 right? I'll take off the small earth-lead and clean the terminals tomorrow, see if this makes a difference.
- at the starterrelay i measure 9,9V between W1 and W2 in stead of 12,4 V with, again, ignition turned completely: possibly it ís a problem with the earth of the relais? Is it possible to, by way of test, replace the earth of the relay and let the connection to the brake-fluid reservoir be, or does something terrible happen then?

If solved earth of relais and solenoid don't solve the starting issues, i'll replace the startermotor with solenoid and see what happens.

Thanks again!
 
SOLVED.

as i measured resistance on the solenoid i checked the earth connection from solenoid to startermotor-house again, cleaned it and sprayed it with contactspray.
This solved the issue: faulty earth of the solenoid.
Thanks again all for the suggestions (i have sure learned a lot searching).
