Hey guys, thanks for listening. Got my '05 24' Champion bay going again after a 4 year lay up. Everything is doing just as it was 4 years ago except that the tach is not working. Has 4 wires hooked up. Blue is the light and is hot when nav lights are on. I am guessing the black is ground. Purple has full power when key is on and grey wire has power when engine is cranked.
('05 Yamaha 300 HPDI) With all that powering up where should I check next? Have tried tapping on tach with rubber mallet while engine running and nothing. Needle doesnt even move when key is turned on. Dont need it but have it and want it to work. Any help will be appreciated.
