Me again, unfortunately.
 
Reference my earlier post of no ignition light with key in the "on"  
position: Fuses are OK, checked some other connections, could not find the body 
 
to engine ground strap (there must be one, right?). If this could be the  
problem, can anyone tell me where it is? I was under and over the car, but 
don't  see it.
 
I suddenly remembered that I have a multimeter (not sure why; I can't  
really use it!). Anyway, the battery has 12V. I changed it for the one out of  
our old Volvo, which also had about 12V, and found that suddenly I have an  
ignition light and, with the ignition on or off, the headlights are fine. I  
pressed the starter button, with everything but the ignition off. There were 
 clicks from the starter motor. I gave it a break, tried it again and you 
could  hear the (gear-reduction) starter almost turning the engine over, but 
not quite.  Bearing in mind the car is positive ground/earth, I put the 
multimeter negative  probe on the starter solenoid and grounded it with the 
positive probe. 10V  showed. I did the same at the starter motor connection 
(main power) and also got  about 10V. Still, the engine will not crank.
 
Any ideas? I wish the problem was just a pair of SU's out of tune; I'd have 
 that sorted in minutes!
