Just put a tach on my sons 00 trailblazer real easy its off off of a Polaris sled and there real easy and cheap to find now my question has any body found a tach that fits a 500 scrambler I had read
and sombody said that they thought that a 6 pole tach would wourk I tried it and it read to high anybody found anything else thanks

 

don't know how to help you but hoped you cpould provide me some help.

I put a sunpro tach on my scrambler 400 following the instructions found on this site, and I have a signal at idle but as soon as I give it gas the tach will drop to zero. any idea what this is?

 

not sure how ya hook your tack but we put one to ground and the yellow to the yellow/red on the wire harness and it would go to 2grand and zero its self out unless you had the lights on then we put the yellow on the yellow on the harness and it worked fine

 

Exhaust Gas Technologies has a nifty memory tach. It's a bit spendy, but it has a memory function which allows you to concentrate on driving the quad, then reading the tach when you get back from the test run.

 

I'm running one of these, http://www.tinytach.com/tinytach/index.php on my 700 and like it alot.
