I can't see anything in the three whole pages about voltage cut-off etc etc..

If the starter battery is charging or below required volts I think around 10.5v then the ctek will not charge the AUX battery until the starter hits 13.4 or 13.7v just from memory when I had mine in the gq

Hmm. The alternator is putting in around 14v to the starter battery though. It say I don't need to earth the starter battery to the ctek. Then I see a Youtube vid from Baintech where they say to do...Paranoia is kicking it, again. Lol. Last thing I want is to eff another aux battery and have warm beer.

I would connect Solar, Cranker and Aux (esp if that is the Baintech recommendation) -ve to the Ctek.

It eliminates any poor earthing or high resistance return.

Mudski, how did you go with this? Looking at getting a D250S soon. I've got a CTEK MXS 5.0 and the thing is brilliant.....

All fitted up well mate. It works as it should. It was a lot bigger than I though it would have been though. I had it fitted in the engine bay next to the aux battery, but now I am doing the conversion I have removed it for now so theres room in the bay for ease of fitment of the new motor. Well, I removed the entire aux side and all wiring so I will start again once the new donk is in and running. I think I will mount in under the lhs dash somewhere this time, to keep the heat away from it.
Although I do like the redarc BCDC1225 better, as I have one of those in my camper, this was shite easy to wire up though. Very impressed by this.
