The original tach in my '00 V11 Sport lasted about 18 months. Now the second tach went dead. In the past two weeks I have been thru 3 more tachs. First one was DOA, second worked for 120 miles, third was DOA (dealer said it was a working tach).
I tried running separate ground wires from the housing and mounting posts. (The bottom mounting post broke loose and had to be JB Welded before I could install) but that didn't get it to work.
At this point I'm wondering if it's the tachs that are the problem. What can I check on the bike to see if the problem is there? Other than the tach, everything is running great.
