12V Power From TV Prob?
This problem just cropped up on the most recent short trip.
For years when we stopped for an overnight dry camp, like wally world, I let the truck power cord hooked up and the truck running until it was bed time and shut things down so we started the night with a full batt if we needed some heat at night.
I usually go by the idiot xmas tree light on the fifth wheel panel. So last time out I pushed the switch to check and only three lights at max with the truck plugged in and engine on high idle (900rpm). Everything was great until the last trip.
I tokkk the batt to town and had it put on the tester. Techie said it was good.
So I probe around underneath front panel and look for the lead coming in that comes from the connector on the truck. I found a black wire that showed 14.2 volts when disconnected from the system. This corresponds to 14.2 volts showing up on the TV batt.
So if I take this wire that shows 14.2 V and apply it back to the system the voltage immediately reverts to battery voltage. it seems like voltage is there but no load can be provided.
What could this indicate? I thought maybe a poor connection either in the box on the RV or somewhere in the truck harness?
I got the voltage but no power (amperage), however it all worked great since 2010. Any thoughts?
