I have a Power Master PMS3H fitted into my Ford Transit conversion. I bought the van 2 years ago.
Recently I had the 3 flashing lights, heater electric fault. While trying to resolve this voltage issue, I appear to have created a further problem, in that, I now have no 12v power to the Propex heater, my 12v power socket or the water heater. Initially I had a fault on the Propex heater with the 3 flashing electric fault code, while trying to resolve this issue, I heard a bleep and then realised the 12v power has gone. I have 12v power to the lights, but nothing else. The 240v works perfectly, just no 12v power. Has anybody any ideas. When looking at the electrics there doesn't appear to be any separate inline fuse to any of the above named items. Are there any hidden fuses on the PMS3H I am unaware of?. Any help would be greatly appreciated.
Thanks, Selbster

Hi again, have now resolved the no 12v supply problem, although the glass fuse looked in tact, putting a multimeter on showed it was blown, fuse replaced and 12v power back on to socket and water heater.
However, my original issue of no power to the Propex Heater still exists, I have replaced the 2amp fuse on the circuit board, so if anbody has any ideas/fix on why no power would be extremely grateful.
Thanks, Selbster

Hi, thanks for replying, I have resolved the general no 12v power issue, it is the no power to the propex heat 2000 now, originally I was getting the 3 flashing lights indicating a voltage issue, while trying to identify why, I managed to blow the aux fuse, but now I have replaced the fuse, I have no power at all to the heater. As stated there is no obvious power connection to the leisure batteries, the wiring comes from the controller switch on the wall, but I can't see how the power gets to the wall controller. Hoping somebody can help.

When Rob and Wolly have drunk you under the table and your talking with Ral you'll not be saying thanks ;-)

Welcome from The Algarve.
There are number of Electric Wizards on here, who might be able to help.
Failing that, give a little money to a local Auto electrician. If you're a motorhomer,you'll get used to spending a little cash, if all else fails.
He will probably become a useful contact if you have other problems.
