I am on 50 am shore power, but have low dc votage 8.8 to 9. Seams like the charger will not turn on. The display shows the charger in standby mode. Any ideas on were to start?

I would start by taking a reading with a multi-meter right at the battery bank. If you don't have one you can get one for $20 at a Radio Shack. There is a large fuse to the right of the house batteries. That fuse in on the charger input line. You will have to check it with a multi-meter also for continuity. The fuses have been known to go if excess water got onto it. Also check the condition of the connections and all grounds.

Thanks for the quick reply!! The condition of the connections and the grounds look good. I am not at the coach now but will check for the the blown fuse. If the fuse is good were would you lok next?

Hi! Do you have the Magnum Invertor? Have you tried to turn it on from the control pad (if you have, sorry about the question) You can open the baggage doors in front of where the outside entertainment center would be, and see if the inverter is running. If the inverter is not humming and you have it turned on from the control panel, there is a reset button on the inverter. I believe on the Magnum it is the power switch. You hold it on for the count of 20. You can also call Magnum (if its their inverter) and they will be of help. If you would like to call me, send me a private message and I will send you my cell number. Maybe I can talk you thru it. Also you can call High Line Service at Newmar and they will help you. Paul

Yes I have Magnum Invertor, I have tried to turn it on from the remote panel, all I get is "charger in standby" I have located the inverter and it is not running. I can see a 30am fuse reset button and have tried to reset with no result. I will try holding it in for 20 sec.

Newmar put me touch with Magnum and had to reset the charger/inverter. Had to kill shore power unplug three sensor leads and hold the reset button above the green led light for 20 sec to reset. Then reconnect each lead one at a time checking the display each time for faults.

Thanks for the help..

MA4529, did you find any fault codes when resetting? You could have had a spike in the power supply if you do not have a surge suppresion system that can cause this problem. I would highly recommend a Surge Guard or similar protection for the coach. Good luck and stay safe.
