Fwd: Flaky rev counter update

[Geraint Lloyd]

Hi all

the rev counter in the 200 TQA 10V just went flaky.

I posted to the 200-20v list and have a couple of things to check after that.

its ok when the car starts from cold, but then goes to zero and stays there
unless you rev the engine to about 5kish at which point the needle swings
wildly to the right.

A search of the archives revealed plentiful advice regarding iffy
speedo's  (and I don't mean a clingy lycra "one piece" number tucked
neatly under a huge overhanging beer gut)
Advice all pointed to cracked tracks on the cluster pcb.

can someone confirm that the rev counter/ tacho has the same issues with
PCBs or am i looking at something else?

As far as i can figure, the MC2 tach feed is from the ECU. is this
correct or is it actually (still) from the coil?

any BTDT?

I will be checking the earths ASAP and have tried slapping the trim over the
ECU really hard with my snow brush to no avail

Geraint
