I have an Isolated Victron Orion-TR Smart DC-DC Charger installed in an 2022 Airstream Flying Cloud 23CB. The tow vehicle is a 2021 Jeep Gladiator Ecodiesel.
I first wired it as the direction stated, Black 7-pin wire to positive input, white 7-pin (ground) to negative input. Then Black positive output to positive busbar in same spot the direct wire was before. And the white negative output was wired to the negative budbar.
In the above configuration none of the outside lights including turn signals and brake lights worked, seems the white 7-pin wire needed to be grounded to have the exterior (7-pin lights) work.
So i rewired it once again returning the 7-pin white directly to the busbar. And wired both input and output negatives to the same busbar. In thid configuration the lights work.
However in both configurations as soon as the charger kicks in the voltage of my alternator drops to 9 volts and the charge shuts off, shows error of engine shut down detection.
I tuned engine shut down detection feature off. And then the low voltage shut off happens when it drops to 9 volts.
In the gladiator at idle it puts out 12.5 to 12.9 volts, when i put it in drive it goes up to 13.2 to 13.9 volts, still idling in the driveway. But either in park or in drive as soon as the Victron Charger kick in the voltage drops to 9 volts. As soon as the charger shuts off due to engine shutdown or low voltage the Gladiator voltage climbs back up to 12.5 volts in park and 13.2 in drive.
A couple of minutes later when the charger kick back on the same process starts again.
Any ideas? Is my alternator bad? Wired charger wrong? Is the Victron Charger bad? Do i need a non isolated charger?
Charger set to lithium, tried manual settings same result.
I am at a loss.
