View Full Version : Ongoing tacho /MDC issue

06-02-2014, 11:10 AM
2000 xstar with mdc1600.

The tacho has been bouncing around all over the place and regularly not resetting. Discussed the problem with medallion, they suggested replacing the MDC (which I did) after having made sure another gauge wasn't causing the problem and also after having swapped over some of the gauge connectors to rule out a duff connector. Note the perfect pass is fine and reads rpm without issue.

I ran a new earth to the bus bar under the dash as I was getting a slight resistance, no improvement, so guessing all i am left with is a bad +ve to the MDC or possibly another bad ground.

Any other suggestions?

Finally, anybody in the UK needing a replacement MDC give me a shout!

I'll be ordering the gauges as soon as I'm paid for an event I worked last weekend.
