Bit of help ! We are in France on a site with 6amp electric. Sargent unit is showing fuse 1 (25amp battery charger) fuse blown - led next to fuse lit. Fuse looks fine, no break in it at all, so does the inline 20amp fuse from battery. I’m not 100% sure if battery is charging or not as I don’t have multimeter with me (to add to the van when we get home!). Over door display is showing. 13+ Volts on battery so I think it’s getting charge from somewhere - we have solar so assumed it to be charging from that. Could the low amps be what’s causing the ghost blown fuse led or is it something else?? Anyone suggest anything else to look at??
