Rev Counter - 1.4 Escort 1992(J) - escort man
Hi,

The rev counter on my car (see above) has started doing some really wierd acrobatics when driving along..

It still rises and falls in time with the engine spped and gear changes, but when cruising on the motorway, it will start darting about all over the place bfore settling down again. Sometimes it will over read by about 1000 rpm for a while before setting down again.

It has always risen when using the electic windows, but its started soing it of its own accord.
Typically it does it when the headlights are on, but not always.
Putting the fan on makes a big difference too - again raising the revs by about 1000.

The problem is accelerated during the wet.

Any thoughts/reasons as to why would be appreciated as the shock of seeing 5000rpms is getting annoying!

Cheers,
Dave

Due to the change under electrical load it sounds like an engine/body earth strap problem. Cleaning the battery terminals will help too. Could be the alternator on the way out.

I would agree with RF on this.

Very strange but, after a trip to the garage where they had to take the dash off for an unrelated repair, the rev counter problems have (touch wood) dissappeared. I didnt mention it to them either.

It still rises when the heater fan is on, but its no longer having spasms all over the place.

either way, problem solved and I didnt have to get my hands dirty!

Dave.
