Power Blips

[Larry Dula]

I have a 2006 American Eagle. We are getting power blips. The light bulbs do not even go completely out. Any ideas. All help is appreciated. Happens many times a day and night.

If all your 12 volt coach internal circuits are doing the same thing , then the coach battery disconnect relay would be the first thing to check .
I'd say to by-pass the relay and test for a night .
Sorry I can't give the part's location in your coach , but here's a photo showing mine ( yellow circle ) If you have a set of jumper cables , connect them from one of the large terminals to the one on the other side, for your test.

If this happens when using shore power, your inverter/charger is cutting in/out. That typically happens when one or more house batteries are bad and the charging function overloads momentarily and then re-configures internally to stop charging and supply house 12v only. Any better inverter/charger will protect itself like that rather than blow fuses or damage the batteries further. You have a high end Magnum model in your coach, so it most likely does that.


Get your batteries load tested. Or if they are flooded cells, check the water level in the cells. Also check for one or more batteries that gets extra warm or shows signs of corrosion on top.
