Hi People,
Well this fault has had me pulling my hair out and driving me insane.
The tachometer started playing the idiot the other week, bouncing all over and then finally stopped all together.
Well found out that the signal wire is the BLACK wire from the ignitor (I believe also the Red/White cable from Pin 11 of the 22 pin connector on the ecu also does RPM)
Anyway did a continuity check from the ignitor to the Tacho head and that tests fine, although when you put a digital mulimeter on the black wire it just shows a constant 14.** Volt, I would of expected fluctuation as its the RPM signal wire ??? so baffled there.
Anyway been through everything I cannot get the damm thing to work,.
Any Ideas???? Am I looking at the correct wire???? anything would be appreciated.
Thanks
Graeme
