94 GL 1500 fuel and temp gauges non op

Post by waynedudes »



I had not started the bike for a while. When I did start it, the fuel and temp gauge did not work. I did the old school thing, pecked on the gauges, wiggled a wire or two. Still non op gauges? So, any assistance on how to trouble shoot this problem will be greatly appreciated. Everything else seems to be working. Thanks in advance.

Find the #3 Relay. Top row, third from the left as you are looing at the panel.


Tap it, wiggle it, remove it and put it back in.
See if that helps.

I have also noticed that the OD, when I shift to 5th gear, and Oil Pressure lights do not light up when I turn the key to the ON position?

Which fuse? Did you check the #3 Relay?

Sorry for the bother. The problem was the 20 AMP relay for tail and other lights! I have replaced this relay about 4 or 5 times in the last few years. Guess I need to get a six pack of them this time.

It may be time to add a second fuse box. Just to split some of the load. The trike does have a lot of lights!

It is probably not the relay itself but faulty contacts that the relay plugs into. The contacts need to be a good strong physical contact with the relay terminals. If not, the contacts heat up and start to melt the plastic they are mounted in and the problem just gets worse.

Mike B, you may be correct? I have cleaned the contacts a few years ago. Will do a good cleaning again. I am also replacing 20 of the rear lights with LED lights. That should also help. Thanks

You may also want to try the relays sold on the site.

I have already ordered 4 of the above mentioned relays.

After further inspection, I find that the relay that has blown 3 or 4 times, may not be the real problem. The area in the Fuse/Relay box where I insert the relay, is burnt and also has some of the side plastic insulation burnt away.

Don't suppose one could just replace that one contact without replacing the entire box? So I do believe I need to replace the entire Fuse/Relay box. To ultimately fix the problem.

Replacing the Fuse/Relay box is something that may prove extremely difficult. To start with, you would have to have a replacement panel and about the only way to get one is from a salvaged bike. But, there should be an easier way to tackle this situation.

The connectors for the relay are nothing more than spade terminal ends.


If the terminals just need to make better contact, you can squeeze them together or replace them.
If the wires and insulation are badly burnt, you can cut them and replace them and install a new connector.
Or you can cut back and lengthen the wires and extend them from behind the Fuse/Relay panel. The relay doesn't have to be in the box. You can extend the wires and place the relay remote to the panel, like under the seat.

And yes, using all LED lights will lighten the load on the terminals.

The area where the relay connects to the female contacts is the problem. The plastic insulation around the lower left connector is missing.

It looks like all the female end contacts for the relay are good. They are not damaged. I cleaned them and blew them out with an air hose. Like you said before, may have been dirty contacts.

I wonder if a little liquid rubber would help to insulate the area? Just in case that is the problem area.

If the female connectors are tight against the relay's male connectors, you should not be generating any heat and the plastic will not melt. Evidently the connections were not tight enough and that is what caused the heat to be generated and melted the plastic.

As to liquid rubber, I think you mean liquid electrical tape. Though replacing the wire would be best, the liquid electrical tape will do a fairly good job of adding insulation to any wire that has had its insulation melt away. Just try to make sure that there is no more heat generated by poor electrical connections.

One other suggestion, use some dielectric grease in the connection, it will serve as a heat transfer medium and prevent heat from concentrating and melting things. Over the years I've fixed a number of repeat loss of contact issues that way. Of course having as good a connection as possible would be the place to start.


Try to learn from the mistakes of others..... you won't live long enough to make them all yourself!
