I've a DP tach on my 2000 m750 that seems to have a short in the connector on the back of the gauge. I know there have been a lot of discussions about replacing tachometers with non-OEM variants.
I was wondering if anyone has had any luck rebuilding a tachometer or knows of anyone who can do such a thing? I'd prefer to keep my DP tach if possible.
Thanks in advance for any advise!
Do you have a picture of the tach?
There are some old DP tachs that can't be opened.
I'll try to get some pictures up tonight or tomorrow. I had it out yesterday and there are some small flathead screws on the back that look like they hold it together.
I didn't think I should be the one rebuilding it. My fiddling has jogged the connector enough that it's no longer functional, so there's not much left to lose.
For what it's worth, it looks just like this:

On the older bikes like yours there should just be a wire from the coil to the tach. You could try just checking all the connections from there into the actually tach housing.
i.e. Make sure the wire at the coil is well connected, then trace the same wire inside the tach housing to make sure nothing's loose. Of course that means opening up the unit.
If that's outside your comfort zone... well, are you sure you'd be comfortable taking apart your existing wiring and hooking up the 8 or so wires to a new unit?
I'm not trying to be a jerk, just trying to be realistic as the only alternatives are to find some 10 year old aftermarket units. And there aren't many left out there.
Mind you, in my opinion opening up your old unit and fixing it isn't that bad. Any competent shop should be able to handle it, and it really is a DIY job.
