Did I kill my Orion tr dc dc Charger?

I have installed a 12/24 DC DC charger to charge two AGMs. It was all working fine but it was taking hours of engine run time for them to come up to the usable 80% charge. So I attached a standard battery charger to them to get them fully charged. I diconnected the cable joining the two batteries but left the output cables form the victron attached. once the batteries were fully charged I reconnected everything started the engine but now I get no lights on and and my app says there is no device.

Did i kill my victron by not disconnecting it? I assumed there was a diode in place that would protect it.

Can you draw a schematic of how you have wired everything and you have disconnected?

I don't see why this should cause damage to the Orion. Did you check the fuses? Disconnect the Orion for a few minutes and reconnect it.

Ask your dealer/installer if that doesn't help.

So you disconnected the wire marked with blue and then connected a standard 12V charger to each battery? The standard charger isn't in the diagram, is it?

Yes I charged them seperatly because my charger is 12V not 24V.

That's what I assumed, but I wanted to make sure.

When you removed the connection between the both batteries and connected the standard charger to the left battery, did you (maybe accidentally) connected the minus pole of the standard charger not only to the minus terminal of the left battery, but also to the system ground?

Except for that I have no idea what your Orion DC/DC might have killed.

This can cause an imbalance of the batteries.
