Tachometer leads burnt up

[jimpittman]

I recently purchased a rebuilt Evinrude1988, 115. The tachometer on my boat was not working when I had the old motor on it. The mechanic wired the new motor to the tach. It would work intermittenly for a couple of weeks, but recently quit altogether. Stuck at 4500 rpm. Well today while I am idlying down the river I smell something burning and sure enough it's coming from my console. The wires attached to the tach were overheating and melted the back of the tach. I killed the motor, removed the wires from the tach and taped them up and restarted and finished another 4 hours of fishing with no more problems. Question: Is there something wrong inside the motor electrical system or do you think the tach just shorted out? What if anything should I do. I plan to call the mechanic that installed the motor tomorrow.<br />Thanks<br />jimpittman

More than likely the tach shorted out.<br /><br />With that said, I would want to check your charging system. Put a voltmeter across the battery terminals and run the engine. You should get over 13.5 volts.<br /><br />If not, the tach may have cooked your rectifier.<br /><br />If it did, not to worry, easy job, not that expensive.

Thanks for the reply DJ.<br />I forget to inform you I have a console mounted volt meter and it was showing well above 13.5 volts.<br />jimpittman
