Rev Counter and Speedo

trukka · Feb 10, 2013

Hi all,

I had to check fuses under the drivers seat for cigar lighter - after that there is no rev counter or speedo function . Also the radio code needs inputing each time the car is started.

I have just checked fuse number 1 - that is fine as are all the others in that fuse box.

P38 4.6 Gems

Any ideas as to what else I can look for ?

Thanks

Has to be fuse 1. Check it again.

the radio needs a constant feed or it will lose all the stations and the code. the rev counter may be a wire on the back of the alternator. and the speedo im not sure poss cable??

Fuse 1 supplies power the radio memory. Cigar lighter is fuse 8 feeding relay 7. Only works with key at least at accessory position.

Wammers - you are correct !!

I swapped fuse 1 ( 10 amp ) with one from another ( fuse 17 ) - started the car - rev counter worked and radio did not need code. I didn't drive but hopefully speedo will operate.

A message then flashed up " fuse 17 fail " so that must be the one I changed. Looks fine though - will change that as well and see.

Well done sir !!

Fuse 17 is all things to all men. Totally depends what year your car is.
