Last year, I started having problems with my tach - it would rev up then slowly die. I checked connections at the control box and at the tach - pushed the 3 pin connector at the control box in to make sure it was seated properly. Same behavior occured with the tach.
I read on here that I can check the battery while under way to make sure the charging system is operating as the tach is tied into this somehow. Yesterday I measured the volts at the battery - I got 12.8 at home before we left. After a bit of a cruise on the lake I got a reading of 13.13 (this was with the motor off). Started the engine and the volts climbed slightly - I do not remember the exact volts at this point, but when underway (I would guess 2500 - 3000 rpm since the tach is dead) it climbed to 14.8 and would stay there. The battery was brand new last spring.
What would I check next? Is there some way I can check the wiring at the tach to see if the tach is shot or if it is the wiring somewhere...? Is there something else I should check?
Thanks for your help!
