I am trying to understand an issue I am having with the control unit on my vw t25 1987 1.9 dg engine. It is an auto sleeper conversion with a Labcraft control unit
This was working fine but I had problems with a split charge relay blowing fuses frequently so I changed it for a voltage sensing unit and things seemed better.
Now when I test the battery at the unit I see only the red led lit rather than it plus amber and green.
The battery input voltage is 12.6v and an attached led light works as does the pump but a usb charging outlet will not work. The voltage supplied to it oscillates between 11.6 and 10.2 which seems strange.
There is a device in the unit that looks like a relay but there is no voltage on any of the 4 contacts.
The only other thing I can think of is that I replaced the standard usb outlet with one which indicated voltage but it worked ok after this change.
Does anyone have any knowledge of this Labcraft unit? There is no model number
