weird noises and lights dimming

[slapshift]

Hello everyone,
Got a question.I replaced my converter and battery and all is going well with that,good charge etc.The problem is my lights dim then go back to bright and at the same time I hear a strange noise like a tree branch dragging on the outer skin.I dont have any tree's around me!It sounds like the noise is above the sink but I cant pinpoint it.I tightened all connections in the elec. boxes,all my fuses are good.I am plugged into the shore and the battery is connected correctly.Any help would be fantastic!Thank you all in advance!

Check the exhaust fan above the stove it may be bad.

It might be your water pump?? mine will do that once in a while when it is trying to pump up the system, it will cycle slow. I have no idea unless you got mice running around shewing wires between the skin and the interior?????

Hi slapshift; It seems to me as you have a short or bad ground. Best way to determine it, is to disconnect your converter temporarily. Shut down all switches. Disconnect the positive lead from the battery. Hook up amp meter between the positive lead and the battery post. Turning on one switch at the time, look for the indication of the draw on the Amp meter. Be aware that amp meter is polarity sensitive, it can read in both directions. If your test meter starts at 0 from left to right instead of being in the center of the scale you may have to switch meter leads to get a reading. If you hear that much noise it must be pretty good short or loose ground wire in that area, which is indicated by dimming lights. If this is the case you have a lot of nasty work ahead of you. However until you can address the issue you can leave the affected circuit disconnected if you can do without it. Good luck. "Boatdoc"

Thanks everyone for your help! I found the problem this weekend and got it squared away.Seems someone moved the thermostat on the furnace by accident to 90.Well with no bottles to kick it off it kept trying to do it's job.Turned off the heater and all is well.
