Well I bought out O Reilly’s auto supply on those fuses 3 of them at $5.00 each. They don’t give those things away. Murphy’s law plays into my life so much I figured buying just one just meant another couple trips back to town and the store.
I plugged in the fuse and just like said the plug was hot at the back of the truck all the time. The fuse held just fine it didn’t pop. I went over to the trailer with the meter and got trailer battery supply voltage level from the plug on pins 1 & 4 so that looked good too.
The screenshot below is from my cell phone app that shows the draw my voltage monitor on the camper seen with no shore power hooked up and nothing on in the trailer including the fridge turned off. You can see it shows a -.20amp draw
I ran the landing gear up and down a little because the battery was fully charged. I was trying to draw the batters down just a little to get the truck to charge it some.
Then I plugged in the umbilical cord from the truck and had the truck running and you can see from the screenshot from my cell again 5.60 amp inbound charge into the battery. I did see over 6.30 amps when I first plugged it in. It didn’t take long for the charge amperage to drop off to 1.00 amp and under as the battery came back to 100% charge.
I think I am at least working now and have some inbound charge going to the batteries so that should help things some. I will see how it all works on the next trip in a couple weeks. Its nice being able to watch what is happening from the truck as I tow.
I had the battery disconnect switch turned on in all cases. But thanks for the heads up on that too. Makes sense that would isolate the battery from charging.
BTW I hear you on the 30 amp fuse blew for some reason. I will be looking over my shoulder on this deal for a while yet.
Thanks for the all the help.
Bob
