2000 900SS, 13,000 miles
My tach acts a bit flakey from time to time on my 900SS. Any ideas what causes this? I don't even know if it's a cable or electronic unit. For instance, this morning, when I cranked, it stayed a 0 for a 15-20 seconds. Then suddenly jumped to indicate 1500RPM (about right, I was warming up with fast-idle partially pulled) and worked normally for a few minutes. It also will just randomly change by about 1000RPM when I'm just cruising along and keeping a steady throttle hand. Doesn't really hurt anything, but just curious about where to go poking around next time I'm doing a little service work ~

It's electronic and is fed off the ecu.
Check the connectors on the bottom side of the gauge unit...
worth a shot.
Thanks dp! I'll have a look see, sound reasonably simple [thumbsup]
