UHG

[new_brunswick]

I have a 2019 Roadtrek with two lithium batteries the voltage is about 13.18 which I think is low I ran the engine for 1/2 hour and no change in voltage. I think my UHG is not suppling any charge to batteries any suggestion as to cause or what to look for ( charges ok when hook up to shore power approx. 13.6v ) I have nothing turn on .

Thankyou Joe

The UHG is a second large alternator, such as those used in ambulances. They are built and supplied by Nation's Starter in Missouri. Those of us with AGMs have a built in controller, those with lithiums have an added Balmar controller that is also provided by Nations.

I second the recommendation of the Facebook groups. There is one for Aktiv owners and one for Carado/Sunlight owners. They know these systems and can answer most questions... and if they can't, they send you to someone who can.

Go to Carrado & Sunlight Owners or Hymer Aktiv Owners and wannabees facebook forums. There are two known experts on the Underhood Generator, batteries and the Balmer. They are Sam CArswell and Lam May something. They are extremely helpful and can give you lots of info about the systems. There is also a Roadtrek etreks and ecotreks forum that has a lot of information on it. I have a Hymer Sunlight Van One with one battery. When there was big gathering in Florida in January with 45 Hymers, they were reprograming and moving many balmers from underneat the engine area to the up by the hood. Great group of people. Good luck

I can't find anything relating to electrical with those initials.

13.2+- is what a sitting lithium battery should be. 13.6v is a float charge rate.
