Dodgy electrics

[steve1781]

I have a 1994 W123 E300D auto. Over the last 6 months have had an intermittent fault where the rev counter stopped, the ABS light bcame on and the kick down stopped (all at same time). Oh, and idle speed dropped. Until now it always came good after a day or so but it now seems permanent. Anyone have any ideas please

Hi steve, to me it sounds like an OVP relay problem,have you checked the fuse on top

Thanks Malcolm
Had a look through other postings and it seems a common problem. They've also given me an idea where to look for it. If I get a dry spell over the next few days I will go hunting for it. Will let you know how it goes.

Eventually found a relay behind the battery which had a 10 amp blade fuse in it. The fuse was ok, could it be the relay itself and how easy are they to come by?

I still do not think that the OVP relay is your problem, but pin 87 has 12v on it if good
