I am having my 12 volt lights fluctuate from bright to dim, especially when my furnace fan turns off. Anyone have a similar problem or a solution
 ?

Are the lights incandescent or fluorescent?
Fluorescents, especially 12 volt versions, are very subject to static electrical interference.

Trini,
Thanks for the Post, I am trying to get the screw for the ground wire loosened, Kind of Tight, Your suggestion sounds very logical,
Some of the other things I seen happening besides my 12 volt lights fluctuating, is the furnace fan blower motor also slows down and the Carbon Monoxide detector light that normally flashed GREEN, will flash YELLOW, then return to Green when the voltage goes back up.
Hopefully it is as simple as a ground wire. Larry

Thanks for the question, My 12 volt lights are both incandescant and flourescent.
I have listed other wierd things I notice when the power fluctuates, see a previous reply.

Plugged into shore power 110v? Running on batteries i get weird flickers. Could be a loose wire in the panel or a converter issue. If your on shore power , It sounds like the converter can not handle the surge from the fan motor and dips low in voltage causing a restart in the carbon detector. Any other thing cause a flicker except the fan motor? Have you tried the water pump?

my lights sometimes 'pulsate' with the water pump when NOT on shore power. It hasn't bothered me enough yet, but I think the solution would be to put the water pump on its own circuit....fwiw.
