Tach Problem

jrbuete · Nov 8, 2008

When I reconnected my battery I noticed a tick, tick, tick sound and my tach needle moved backwards so it was at about the 2pm position... With the engine running it reads corresponding low so I disconnected the battery and when I reconnected it it ticked back another 60 degrees or so...

I did this until it was where it should be to give readings that match the dial but this has never happened before...

Ideas???

Thanks!:dunno

Sounds strange, I know that the instrument pods self test and go to base settings when powered up after a disconnection period but I can't see why it would move the tacho needle to that extreme.

Was the ignition and all electrical consumers off when you reconnected the battery?

If not it could be back feeding via the activated circuit.

Yeah... normally when the ticking occurs you could see the needle move(jump a little) but it never went anywhere...

Thanks

I have a sinking feeling a diode or something in the instrumentation got fried
