Erratic Rev Counter

[Jolly Green Monster 51 1 Cars]

As subject. Flickers all over the place. Worse with lights on. Bad earth?

 

205 gti 1.6 with gti6 conversion.

 

Any common things to check?

 

Tried search but couldn't find anything

 

Thanks

Simon

I had same, battery box was loose and battery was bouncing about all over!

Depends on how the Rev C is modified really, Could be a loose connection or a failing adaptor

Battery is solid.

 

Will investigate how it has been altered

 

Thanks

Mine did this. Was todo with converting the tacho so it worked with 16v. I soldered the two contacts with a wire and it did it. (guide on here how to do it)

Never found out why as I bought a Stack Dash!

Mine only flickers for a nano second when I load the electrical current. I converted the clocks for the record.

It has also been modded on the back of the clocks.

 

If it were for a nano second only I wouldnt worry.

 

Will go over the wiring and worse case fit an after market rev counter as its currently unuseable as a rev counter

mines nearly the same as this. if the engine speed drops below 1000rpm for a split second whilst the ICV gathers itself, my needle shoots up a bit then settles ok. wiring mod to rear of binnacle same as the guide on here.
