If your Scamp
has the "American" brand converter, welcome to the club of fried converter owners. (As are we). As such, I suspect that you are not getting any DC voltage for lights
, fans, pumps etc. when connected to shore power either due to a fried converter board.
If this is the case, first choice is to buy about a 10 amp battery charger to keep your battery going until you get home, but be sure to disconnect the converter section of the power supply from the battery and DC loads to prevent any feedback from the smoked converter from getting to the charger. You can do this just by disconnecting the converter circuit board from the chassis, it's s a plug in board.
When you get back home you have at least two choices:
a) You can buy an updated board from the American distributor, about $90 at last check, but you will still have the old, somewhat marginal ac & dc distribution system left over.
b) You can install a new converter/power chassis such as the Progressive Dynamics PD-4045 that will allow a 2013 update to your entire electrical
But, good luck on the rest of your trip
