Hi all,
As this is such a useful place of knowledge, thank you to all!
I have a 230e, 1985 W123 series. Brill car, had it at least 13 years and took it from 82,000 to 216,000 miles. I have an intermittent fault which has exhibited itself only 3 times.
Last summer, I went from North East to Dover, stayed at St Albans overnight on the way. Car performed faultlessly on the way down, started and went ok the next morn, but half way round the M25, it suddenly lost power and stopped. It wouldn't restart, or even fire when turned over, so I lifted the bonnet and couldn't see anything obvious. I only touched the ht lead on the coil, it wasn't loose, then shut the bonnet and the car re-started perfectly, ran perfectly. I couldn't understand as I hadn't done anything, so went on my way. Went to Dover and returned home, no problems.

About two weeks later, had popped out one morning, on way back home, same fault, car lost power and stopped. I lifted the bonnet, spotted a wire loose from a terminal connect block leading off bottom end of the coil, thought this must be the problem, although I couldn't understand why the car would work if it was loose and meant to be connected. I joined it up, the car started and ran perfectly, I got home and made the joint fully secure, thinking that was now it!

Another few weeks later after perfect occasional use and running, I started the car, drove about half a mile and it again stopped. I couldn't restart it, despite waiting the usual few minutes. I was with a friend and got him to wait in the car whilst I wnet back to get my van to tow it back - he rang me after 5 mins to say he had re-started it, so I walked back, only to find it had stopped.
We towed the car back home and that is where it has stayed for a few months as I haven't had the time to look at it and also someone had promised to come to sort it out and hasn't turned up.

So, before I start with the usual fault tracing process, has anyone ever experienced something similar andresolved it so they can point me in the right direction?
Cheers lads,
Andrew

Charger coils

Hi Nick,
Now I'll show my ignorance! I'm not sure, what is a charger coil and where would it be situated?
thanks,
A
