finicky temp guage

My temp gauge has started to peg out recently. It will work fine for a bit, then peg out. Sometimes it comes back and sometimes it does not. The sender is brand new.

When I pop the dash and move the purple signal wire, I can get the gauge to work normally. I've replaced the terminal end and notice that if i hold the wire a certain way the gauge works as it should, if I move a little more it pegs out.

I have a feeling there is something wrong inside the gauge. I've seen the Faria replacement and it is pretty different than what I have. Any suggestions on where to get a closer to stock replacement or any ideas how to fix the OEM?

If not, Check out Summitracing.com - Cockpit White.

2 replacement issues:
Temp range is different therefore sender change would be smart.
Pointer is different color

But they are a "match".....

Rod is the EBay one...... Velde99 on this site. PM him........

When you say peg out, do you mean it behaves like they key is switched off or the opposite?

I noticed one little oddity with one of my faria gauges one time. It was actually just with the dash lighting part, it worked for the temp, it just wasn't going on with the dash lights.

Basically, the post itself wasn't connected, their was a brass trace strip on the rear that the post went through, and my ring terminal had to be pressed against that brass trace strip directly.

Long story short, make sure your ring terminal is basically solid on the post, maybe pinch it between two nuts instead of just using one nut to press it against the back of the gauge, and if the Ignition Post goes through one of those brass trace strips, make sure your ring terminal is hitting that directly.

Hey John!

I have the same issue with my 92! It has been good with a "tap" to the glass, and then got worse, took a few taps. I took the dash off, cleaned and tightened all wires, put it back together, and worked fine for about a week or two, and now requires the "tap" again. I am starting to think it not the wires at all, but the gauge itself?

The tap would get it to work on occasion. I've checked all the connections and actually cleaned them all when the dash off during the re-gel. When she's running and the dash is loose I can add a slight touch to the signal wire and she works like normal. Once I let go and the wire moves again, she pegs out. I also notice some movement in the gauge face when moving the wires. If I can get the wire in the right spot, she'll work fine. Once there's a vibration or bump, the gauge will peg out.

Sometimes the gauge will come back, sometimes she won't. I'm pretty sure it's the gauge. I just want it fixed in case I ever have a real temp issue or for when I'm not the one driving.

I'd like to keep it stock, but know that may be hard to achieve. I think the Summit unit is the closest to stock. I'll just have to see how for it and the new sender.

I just took some old wire (about 6ft) and soldiered alligator clips to each end. I disconnected the the old ground from the gauge and ran the new one to the engine ground. I guess it depends on which side your gauge is pegging. Mine was going full scale. I went through the same process last year with my 96 and it ended up being a combination of the sender and ground wire causing the "peg". Next season I will probably redo all the grounds and install perfect pass as it's a notorious problem.

Mine pegs out past 200.

I ran a fresh heavier gauge ground wire from the motor to a new bus bar under the dash last year. Also ran larger ground wires to all gauges in the dash to said ground bus. I'm pretty certain it's the gauge. The sender is only a few months old as well. So far I think I am going to go with THIS gauge. It's closest to stock. I think I'll need a new sender, but I havent looked into that yet.

FROM A POST HERE IN 2004!! North Hollywood Speedometer, www.nhspeedometer.com.
I spoke with them and they can rebuild. Asked for a picture. I sent. Will let you know, the guy I spoke to said about $60, American.

Go to autozone (god I can't believe I said that) and get the cheapest temp gauge they have in stock. I got one for $12.

Hook it up and run the boat to see if it does the same thing.

Then at least you know for sure before getting one rebuilt.

I'd love to stay stock, but I missed the last one by 5 days. Rod said he would contact me if he came across another one. I've searched around and can't find anything. I may be able to wait it out a bit longer.

If yo come across anything, please let me know. Gonna see how much Summit wants for the sender too.
