A few weeks ago I did some umbilical wiring repairs on my fifth wheel camper. When was checking everything out, I discovered the trailer battery wasn't getting charged by my tow vehicle. It turned out there's a five dollar 30 amp fuse in the truck to protect that circuit, and it was blown. There's also a 30 amp circuit breaker on the trailer side, but the fuse blew first.
Since this discovery, I've added another check to my normal lighting checks: After hooking everything up but before starting the tow vehicle, I check the trailer battery's voltage. Then I start my truck and check it again, making sure that the voltage is higher after starting the engine. The voltage will only rise a couple of tenths, but it's charging.
I suspect the blown fuse happened when I ran the trailer battery completely flat trying to operate the camper's furnace during cold nights at Yellowstone. I now carry a spare fuse, but haven't needed it. We just finished a 1200 mile trip around Lake Michigan and had no electrical problems during the trip.

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
