Tach and Trim gauge

7 posts in this topic

My tach and trim gauges are not working. I went out and bought new gauges and put them in today...and nothing. I tried to follow the wiring and everything looked ok. Any ideas what might be causing these gauges from working? Also noticed that after I put in the new gauges the tach goes up to about 1000 RPM's when turned off? Then when the key is turned on it goes back to 0. Never seen that before. Any help would be appreciated.

I have been looking and came up with maybe my rectifier is shot. Does anyone know where the rectifier is located on a 150 Johnson?? I can't seem to find it.

Can you provide a little more background on this? Has either gauge ever worked? Did they stop working after you made some changes to the boat / added accessories?

The tilt & trim gauges are not connected (other than power 7 ground) to the tachometer, and the rectifier has nothing to do with the trim gauge.

If you can provide a little more background it would go a long way to pointing you in a direction to solve your problem.

The 2 gauges have not worked since I have owned the boat. I am selling the boat now and thought I would try and get them working before the sale. I thought the gauges were just shot but I put new ones in and still nothing. The wiring all looks good. Where does the tach wiring run too? Does it go back to the motor and hook up somewhere? Where is the rectifier located, I don't see it anywhere under the counsel or behind the control panel?

Bad (+) or (-) would be my first guess.

I agree with BobT, Had a Jonny that the owner installed the battery and hooked the battery cables to the wrong posts. He got a small spark, realized his mistake and switched the cables. That first outing his tach didn't work, but could live without it. Later that season his starting battery wouldn't charge, so he finally brought it in. Yep, rectifier was shot. Replaced it and marked the battery cables REAL well, he hasn't been back since. Phred52

I'm not certain the rectifier is the problem here.. it shouldn't have taken out the trim gauge as well.

Ace - take a test light / multimeter and verify you've got power at the purple wire or I post on the back of the tach and trim when the key is on, and ground at the black wire or - post on the back of the trim and tach. Let's make sure the gauges have power before we start checking on the motor.

    • Looks interesting. They have those nets that you put down a hole that do the same thing, but I can see where some people would prefer this more solid version.
    •   The land in question is a 40 acre parcel up near Remer. My FIL's uncle has owned it since my FIL was a small child and he has been spending time up there ever since. It's a cool parcel of land with lake frontage but it is hard to get to. The last mile or so is basically an ATV trail. When it is dry enough we can get in with trucks but the last time I was up there there were a lot of trees across the trail that would need to be cleared.    I would love to be able to own that land but ultimately it has to be an immediate family member. My FIL says he was supposed to inherit it because his dad used to be half owner as well. It is looking less and less likely that will happen because the current owner's wife is in a nursing home and the money has run out. We think there may be a lien on the property already but don't know for sure.    My FIL needs to talk to his uncle about the situation before it's too late but I think he is holding out hoping to inherit it. I hope that happens but I'm pretty sure it won't.
    • This is a good way to keep them crisp
    •   I was just wondering where it was since you said you needed a 4 wheeler to get into it. I know the woods up in that area pretty well after years of hunting, snowmobiling and Dual Sport riding all over. Not thinking of buying but just wondering where it was?
    • I'm not fighting with anyone.   Many ways to make antennas, and for receivers in cars wavelengths aren't all that important.   Class up your vehicle with a wire nut or a fox tail or whatever you like.  
    •   Still a possibility but due to family dynamics it would have to be a joint venture with my FIL. He is the one that would have to technically make the purchase and we would go halves with him but he isn't doing anything about it right now.    It may still be a possibility but I'm not holding my breath.
    • sounds like draw length is too long
    • Wax all the string except where the serving is as the wax can get under it and cause it to slip   You should be able to tell the serving because the string will be thicker. Serving is just a thin string wrapped around you bow string. Will be around your peep sight around your d loop   If all else fails just go to your local archery shop and ask them for some pointer about waxing and other general bow maintenance that you should be doing hope some of this info helps though good luck!
