Problem With Temp Guage

Postby rolan » Wed Jun 16, 2010 3:18 am



I have a 2004 Honda Goldwing 1800. The temp guage started showing hot, but the water in the radiator was cool. I noticed ever time I hit the brakes the temp guage would climb up. Has anyone ever had this problem.

Does the temp gauge show all the way HOT? If it does then there's probably a short that is after the thermosensor and before the gauge. I don't recall the temp gauge being controlled by a relay so that shouldn't be the problem.

The brake thing could be a clue... any chance you've got a modulator or added brake lights wired into the front fairing area?
Is it possible you've used a wire in the instrament panel to power something related to the brake system??

The temp guage does go all the way to hot. The only wiring I've had is the Honda Shop wire it for pulling pulling my camper. They said that what they did was not the problem??????? They said they would have to take the complete trike apart to find the problem. At $85.00 and hour, I don't think so.
Just by hitting the front brake or rear brake you can see the temp needle jump.

Did this just start happening when the trailer wiring was installed?

This did not happen before the trailer wire was installed. Now that I think of it, it started about 2 days later.

Sounds like you need to trace the trailer wiring and see what they have done.. If you connect the trailer electrics does it still have this strange behaviour? Just wondering if the problem is there with the trailer connected or disconnected? If there is a difference in behaviour we might be able to suggest something.

There is no difference, with the trailer hookup or without.

Oh well, bang goes a few ideas I had.. Sounds like you have to follow the trailer wiring and see if they did something weird. Then if all looks good we can start suggesting other things to try but we need to eliminate the trailer wiring first.

I would assume they used a trailer isolation harness...I would also assume that they followed the instructions and tied the main power for this harness directly to the battery---if they did not and are tapping a power wire for something else to power the isolator, you could encounter this issue and in fact would be eliminating the true purpose of the isolator in the first place...
