Bartdog

Problem solved, many thanks to all & Heritage, problem was the leisure battery's isolation switch not quite making. Gave it a birthday ( & the starter battery switch ) & all is well>> Bartdog>>

I got what i thought was the full documentation / manual, but the heritage manual refers only to one of the appendicies which details the individual fuse circuits & not the feed to the fuseboard. Ive already been on to heritage for electrical support, but still awaiting assistance. i'll get on to them again & ask for the full diagram Bartdog>>

Thanks to all, yes it's going to be a case of tracing back, as noted it's got to be a trip or reset between the fuse board rail & batteries - will report back>>

Wonder if anyone can assist in this one. I've got a 2002 heritage cruiser, which has both 12 volt & 230 volt electrics. This last weekend in a bid to conserve battery consumption I back fed 12 volts dc from an external power supply unit, on to the 12 volt +ve & -ve rail of the fuse board. I've done this many times on my previous boat with no problem, it feeds the boat 12 volt electrics & charges the battery, when in a marina. However on this latest boat, when I disconnected the external 12 volt supply I was left with no battery voltage on the fuse board 12 volt rails. I've check all batteries starter & leisure & the battery voltages are fine, it's just that no voltage is getting from the battery's to the fuse board. Interestingly the fridge works fine as this is fed (via a fuse) directly from the leisure batteries, indicating supplies are healthy. Just wondered if I'm missing something obvious with this latest boat, is there a cut out / relay etc inline with the batteries that I've missed? Any pointers appreciated>> Ps it's a 2002 heritage cruiser>> Pps yes - both battery isolators so were on>>
