Need help with a sleepy tach.
So, I put a deposit on a 1997 1100XX yesterday...
Apparently the tach on it broke last year. My question is... is the tach on that bike mechanical or electronic. It seems that when it broke, the needle began to behave erractically, then spun around behind the needle. When I rode it yesterday, when the revs got up a bit, the needle would come back to life a bit.
Any ideas on what is going on here?

The TACH is electronic, so it sounds as if you have a loose connection or a low battery??? But I would say it is a loose wire

Any suggestion on where to find details on getting into the dash? I haven't looked...perhaps an easy thing to figure out.

RE: Need help with a sleepy tach.
I can get a new tach on ebay pretty cheap...
Any one have an idea if this is likely to fix the problem?

RE: Need help with a sleepy tach.
If your tach is like the older 1000's, it is electronically driven off the spark unit. The first thing I would do is find the connection(s) from the tach down to the spark unit. I would take each connection apart and spray contact cleaner in the connection and put it back together. Then I would check the ground. But if that is the only electric thing that is malfunctioning, it is probably not a ground since usually several things are ground together. A wiring diagram would probably help. Of course, it could be the tach, but usually it's a wire that has a bad connection or is grounding on the frame somewhere.

RE: Need help with a sleepy tach.
I did end up getting a Haynes manual. It was a great help. From the diagnosis in the book, it looks like the problem is in fact the tach...but I am not confident in my multimeter skills to say for sure. Any suggestions as to where to buy a used tach...or a new one for cheap? That one on ebay went for $26! Now all I find is a parts store online for $286. Ouch.
