Hi guys,

Having issues with rev counter on HGT(mk1) intermittently working, checked relays and fuses. Had dash out and checked connectors to rev counter all seems fine but still has a mind of its own.....

Is there a connection further down the line somewhere that plays up, maybe something under bonnet or are the rev counters themselves known to fail.

Had that on marea (155) after disconnecting battery, usually woke up after an hour or so.
Has not appeared after engine and chassis earth from battery were redone.

Cheers for that....
Had another go at checking all connections and fuses over weekend and cleaned up earth leads.....worked for longer periods yesterday and has been fairly consistent today.....not sure if just a placebo effect but seems to sound healthier when rev counter working but can't see why it would so prob just me being a numpty.lol

Have you tried the big main harness plug under the bonnet, that one is well worth cleaning.

Had exactly the same problem and once I had cleaned up the earth cable on the gearbox it was better so I installed an additional earth running from the engine direct to the (-) of the battery, this sorted the electrical gremlins out!

cheers....yeah its still doing it and gone through the dash wiring, not getting a meter reading on the rev counter connector so had read that the gearbox feed(module ??) causes problems so thats where will be looking tomorrow,so will give earths a go at the same time.
