I don't have ecotreks. However i have read enough posts about it that one thing i know-trying to judge lithium using AGM formulas is problematic.

without a true SOC device like in ARV's it's pointless

IIRC I think you need it if you require regular GU operation.
I didn't think Roadtrek installs the high-idle option.

There is always the after-market redneck version.

An ammeter would explain what is going on.
13.2V at 120 amps = heavy load, alternator working hard, trying to keep up.
13.2V at 10 amps = light load, alternator working easy, regulator still keeping it in float mode.

Found the Balmar under the hood but it has no display with shore power or with the engine running. Gonna try changing out the 1 amp fuse with a 10 amp even though it doesn't look like the 1 amp fuse is blown. Hopefully this is the quick fix to the GU issue.

10 amp fuse didn't change anything. Balmar LCDs are not showing anything. So I'm guessing for some reason the Balmar isn't getting power and thus the GU is not supplying charge.

My primary mission in life is to kill all this specious Internet talk about various things "voiding your warranty". In the US (at least), this statement is always false. NOTHING can "void" your warranty--certainly not tinkering by the owner of a vehicle. You will not find such a claim in the Sprinter Warranty book. You MIGHT find one in RoadTrek's literature, but if you do, it is BS.

Now, if your tinkering ACTUALLY CAUSES DAMAGE, and if the OEM can prove it, then the warranty will not cover that particular damage. That is because your warranty doesn't cover such damage. But, all warranty coverage remains intact, by federal law. Moreover, the burden of proof is on the OEM, not you.

I am NOT saying that you should tinker with things you don't understand. But the reason you should not do this is because you might break something that the OEM won't have to fix. It has NOTHING to do with your warranty. So, if you DO know what you are doing and are so inclined, then hack away.

That is certainly your problem. The display on a functioning Balmar regulator ALWAYS shows a sequence of flashing codes.

I found it in the Sprinter owner's manual but haven't yet looked at the warranty book.

That's good to know, thank you.
