TR20 Tachometer

I went out today and noticed the tach wasn’t working. Wondering if others have had this issue and if there is a more common issue where I should start looking.


Thanks for any advice

I have the same boat/year............my tach was working but it was erratic, needle jumping around, I had to replace mine

Thanks, I did notice it last week being a little erratic.

Team Mud where did you find a new tach at? Were you able to find a match to the original?

A lot of times corrosion gets in it. Sometimes unhooking it and turning the knobs on back and checking connections will fix it.

This, mine was reading way off. I took note of the positions of the knobs, turned them back and forth a few times, back to original and thing worked again.

Thanks for this tip guys, I will check the connections and knobs.

I was lucky, my brother is a marine mechanic and had a new one kicking around that he gave me. It wasn't exactly like the one i took out, but it works fine.

Mine was bouncing all over the place and fixed it by messing with the switches on the back
