I've identified a strange problem and possibly my NON-isolated dc/dc tr orion has gone bad? when battery 1 is connected to 'IN', the voltmeter is showing about 11v between boat negative and the negative/common (middle connector) on the controller. could anyone try to explain why is this happening?
The other side of the voltmeter is connected to the negative buss on the boat.
But you have not connected the negative side to the battery, just the positive, so there is nothing to drain the positive voltage, the positive voltage goes into the unit but can not come out so the whole unit gets to close to the supply voltage.
Nothing wrong here.
That's the point. The battery negative already connected to the common buss. why would positive voltage read on negative connection of the Orion? Is my controller bad?
Did you somehow solve this? I've got the same issue here. The ECU of the engine is giving issues, the only thing we could find is this so I'm hoping to sort it out by solving this issue.
The negative of the Orion should be connected direct to the common negative.
