Tachometer issue...

Post by Oxymoron » Mon Oct 29, 2018 12:49 pm

Hi
My tachometer has started to stop working on an intermittent basis!
It may not be working at the start of a journey and then start working or vice versa!
What's the likely cause?

Cheers
Jez

I've checked the earth and that seems ok.The bulb that illuminates the rev counter won't work if the earth is disconnected, but works ok when reconnected.
Which wire from the coil do I need to look at?

How are your volts? I've had a tacho apparently stop working when very low on volts.

Well I seem to have solved the problem when I got the car out of the garage for the first time this week, as I found a hidden bullet connector in the wire from the coil which was corroded.
A clean with some fine wet n dry paper has revived the rev counter.....Touch wood!!
