Mreg 300tdi

got this in nov last year and since getting it it has had a problem with the rev counter ..at tick over or while driving the rev counter bounces by about 500/700 rpm even if your on motorway at a steady road and engine speed.
got me completely beat have any of you had/fixed this fault

check the spade connector on the back of the alternator, pull it off clean it and I bet it will cure your problem.

The rev counter gets its fead from a wire to alternator make sure its got a clean connection?

It's fed by a wire from the alternator, check the contacts on the alternator and make sure they are clean and not corroded.

I'm sure more knowledgable chaps will be along with more info

LOL....
you would think so but just found out needs swivel pin and bearings replaced.
as when i took it my local 4x4 garage they checked/adjusted wheel bearing on N/S/F and found that it needs doing so may aswell get him to put new wheel bearing kit in at same time .....:censored::censored:

blown diode on field winding.
it'll still charge, but not as well.
budget for another for when more diodes pack up and it stops charging.
ignore the rev counter.
oh, and check the connections.

Have you checked the signal wife from the alternator?? Sometimes they get corroded up, cut it off and crip anew spade connector on......

thats not to bad on the parts list for 12 months. Oh and check the spade connector
