Unhappy No Power from Battery


My 71 International has a new marine battery. No lights or fans are operating with the old or new battery. I have power to fixtures when it's plugged into the truck or 120V.

I have checked fuses in my converter and the breakers for my 120 power. I also tested the cables down line from the battery and I have power on my volt meter.

Any suggestions on where to check next. I'm stumped!!!

Thanks, and Cheers

Check to see if you have a battery cut off switch located somewhere around that battery box. This is used when the trailer is parked for extended periods when you are not camping so the battery will not drain down on you.

No turn off switch. The only thing in that area is the polarity light.

I believe there is a government regulation that requires a breaker on the negative cable from the battery to the distribution panel. My last SOB trailer had one hidden under the bed. Almost impossible to find. IF I remember correctly, the breaker is supposed to be within 3 feet of the battery. Follow the negative cable from battery to distribution panel. If there is anything on the cable, it is likely a breaker and it is likely to have tripped. Good Luck.
So Long!

John, I have a 1970 Overlander which might have similar wiring. The power from the battery goes directly to the converter through a 40 amps fuse on the fuse panel inside the converter. On the schematic this fuse is listed as"d" and Trailer Battery+. The negative wire from the battery goes to the same fuse panel in the converter terminal listed as k, which is one end of the shunt resistor and the other end "h" should go to front connector and ground. The shunt resistor has two smaller wire going to the ammeter on the control panel. If you would like a schematic let me know.

Live and LET live
