Anyone have specs for a DBE-150s, wondering what the cut in and cut out voltages are supposed to be ?

I have one installed in in the cruiser (was there when purchased)
On a recent trip i was checking the battery voltages and the isolator was not charging the second battery until the main battery was well over 14 volts.

Seems to be a bit high of a cut in voltage to me but I can't find any details of how they are supposed to operate.

My matson isolator cuts in at 13.3 volts and starts charging the second battery on my other vehicle, this seems better to me as I can usually just idle the vehicle and it will put a fair bit of charge into the second battery but the piranha requires me to go for a rather long drive to get a decent charge into the second battery especially if some power has been used from the main battery.

Thanks for the link, buggered if I could find that one....

I have read a few other threads and cleaned the isolator earth contact as suggested in one of them and it now seems to be operating as it should.
