Electrical Problem Loosing 12V

by Rich
(Grand Rapids, MI)

Question: I have a 2005 Keystone Cougar Bumper Pull, When i plug the trailer into the receptical for power all Electrical components work. However once everything is running for a while any electrical powered devices including a/c shut off and within 5 minutes or so they turn back on. My lights which are plugged into the GFI outlet outside of the trailer are still on. So i then flip the circuit breaker and the interior lights flicker and stay off. The lights flickering when i flip the circuit breaker lead me to believe that there either a short somewhere in the inverter, or circuit breaker or fuse Panel. Any ideas?

Robbie: From the information you provided I believe your having a converter issue. I would first (with you unit connected to 110V) push your Battery Condition Button on your control panel and see if its showing a full charge to the battery. Then I would check Voltage at the battery and see if the charge is making to the connections should be about 13.4 and battery connections are clean. If your 110V is remaining on and lights flicker then your trouble is in the 12V system. Note: Your AC shutting off is because your loosing 12V to the Computer that turns the AC on and off if your Thermostat is on the wall. If you have a Inverter/Charger then the Charger side of the inverter could have a problem and some have a reset button on the side or rear depending on the make and model.

Thanks for the Question Good Luck,
