Rev counter

[elty001]

Just a quicky, I've been working on a 1999 2.7tdi, bosch set up.
Had battery disconnected for welding but now it's up and running again I've got no rev counter.
Just wondering if there are any obvious places to check for a fault??

Are they driven off the gearbox?

dont know mate tbh,that was my first thought so i had a look to see if i had caught any wires while working under the truck.
I dont actually know if it was working when the guy dropped it in with me,just one of them things ive got to fix as its bugging me!!.

Rev counter is driven from the ECU getting its signals from the CPS, Rick

Thanks Rick :thumb2
So most likely a wire or sensor fault.

will not be the CPS as would not start if bad, more likely dash connection problem, Rick

That gives me a starting point to work from.
