On my 2000 Weldcraft I have rpm, oil pressure, temp on the left of the steering wheel. On the right I have voltage and fuel level. When I adjust the dimmer for the light the voltage and fuel lever move to different positions. I looked under the dash and all connections seem clean including the grounds. Any ideas?

thanks!

"Seem Clean" is not good enough, you need to take them apart and clean them to make sure they are clean, first rule of electrical troubleshooting is to make sure the electric has the cleanest path possible and that takes more than looking at them. I spent to much time in the RV business helping my buddy out who owns a manufacturing facility to depend on "seems clean" do it the right way and you will track down the problem.

I am going to bet the contacts in the light switch are dirty and interfering with the electrical path.

Many of you guys don't remember growing up in the day and age when you are driving down the freeway at 60 mph and you hit the switch on the floor to dim or brighten the lights and all of a sudden you didn't have any lights, dirty dimmer switches were a pain in the you know what!

You could be riding a British motorcycle when the Lucas regulator bites the dust and all the lights burnout, so you hit the brights for about half a second. Then you have no lights on a moonless night!

Anyway, another thing to check is fuses if you have then. The contacts can corrode and a possible symptom due to low voltage is wonky gauges.

Awe crap, that brings back scary memories when I was in Britain when I was first stationed overseas

:eek:

It is amazing how many sheep they let run around in the dark!

Thanks for the help. I’ll pull the dash out and clean all the contacts. Going to be fun since there’s only about 1,000 of them!

Sorry buddy,

Nobody ever said that owning a boat was always going to be fun!

That's why the Brits drink warm beer. Lucas also makes refrigerators.
