12 volt interior dome lights on 1995 265 fiesta Vee very dim and unstable

darren

I started replacing the old, burnt out rv bulbs to led's and I am getting some power to my dome lights but it is erratic and dim, occasionally very bright, (I have multiple brand new bulbs and they all do the same thing) I googled this and on several Rv forums, it said it sounds like either a dying battery which in my case, both batteries are fine, the 454 starts right up, so they said if it is not the battery, then it has to be a malfunctioning "converter". What and where would the equivalent to a "converter" be located on my boat? I have 2 batteries and the switch to turn them off, on on, or both on, and right beside that is a charge meter, is it within those 2 things??

The only "converter" I can think of would be an inverter.  It's not uncommon for RVs to have 110v AC lights instead of 12v DV.

It's more likely a bad ground for the light fixture.  I'd trace the wires for the light fixture back to the source and make sure the ground is good.

+1 a ground problem or corroded wires

I was getting erratic low voltage to my cabin 12v outlet. I replaced the breaker and it fixed it.

Is the breaker for a 1995 the small white button breakers at the helm?

The boat is built around those wires, so hard to trace out, any suggestions/

Pull out that panel and check all connections

Check the ground on the DC side of the power panel when you get it pulled out.

So, pull out the breaker panel at the helm that has the old white small button breakers?

Try moving the wire for the lights to a different breaker and see if the problem follows or goes away.

I think there is a panel down in the cabin.  The lights should be routed through there.
