Dodgy Rev Counter

[1fast6]

Ever since i bought my 1.4 RT the rev counter has been dodgy.

When i start the car it will work for about a minue sometimes less than that then it cuts out. So for short journeys i am without the rev counter.

But if i am driving for more than 1hr/2hrs it will tend to all of a sudden start working again and keep working until i turn off the engine. then when i restart it its dead again!.

Has anyone ever experienced this problem with their rev counter? or a similar one? i spoke to a bloke months ago who said it could be a mechanical fault or the sensor in the gearbox.

im hoping its the dials not the gearbox sensor, shall i just replace the dials?did that cure the problem for people in the past?

cheers

Take the dials out and clean all the connections then try it again !!

the rev counter gets its info from the coil module.

jay is the coil module able to die or cause an intermitent fault?

trouble is, because it works sometimes then not it sounds like an electrical prob.

could i test it using an ammeter?

Chris, when i say it cuts out i mean it is at say 3000rpm then will drop to zero (rest) and stay like it. I guess this isnt what u meant by it sticking?

 

[JAY172]

i would check the coil connections and instrument panel connections.carry out a continuity check of the wiring between these two parts.i would have to check the connector pin numbers/locations though.

 

[1fast6]

where abouts is the coil connections? can u get to it from the engine bay?

 

[JAY172]

the coil is bolted to the n/s inner wing or the bulkhead.

ok ill have a look. may just be a dodgy dash tho. i have tried to get the dash out before but havent been able to get the speedo cable to detach. do i have to twist it or does it just pull out?

 

[JAY172]

you squeeze the end and pull it off.you can normally flick it off with a screwdriver.remove the lower dash trim and you can see the cable.put your screwdriver up the gap and flick off the cable.you can also push the cable back on this way with a screwdriver if theres not much slack in the cable.
