Hi my name is Robert.....

Are you plugged into shore power? Are you missing but the AC and DC voltage? The AC voltage would be the microwave, TV, outlets etc.... OR are you unplugged and have no DC voltage???


Customer: replied 1 year ago.
Not plugged in to shore power, just the battery and no power
Customer: replied 1 year ago.
No DC power coming in

First verify your voltage at the battery, make sure it is over 12 volts, next follow the cables and look for a tripped breaker, below is a picture. As a general rule they like to stick them 18" from the battery and can be on the frame, most have a tiny tab on them that will pop out when they trip. IF you see any at all I would check for voltage on each post, the voltage should be very close, if one side reads higher (to chassis ground) then it is the problem. IF it is not a breaker or fuse problem in-line it could be an issue with the power converter, it will take the incoming AC voltage and make the DC voltage when you are plugged in and then switch over to battery power when you unplug. Some converters are part of the main fuse/breaker panel and others will stand alone and plug into an outlet, the stand alone style will have two fuses on it, or at least the majority do. IF you have more questions or concerns please feel free to contact me..... Robert
