I have just returned from a trip and on the way back at a lunch stop I noticed that the fridge in the front box wasn't working. Checking inside I found that there was no power anywhere, there was no light on the main 12v override switch and no 12v lights or the water pump had any power.
I called Track (from Nth Qld at the timne) and though they were helpful, we couldn't diagnose the problem. I checked the 2 fuses on the AGM batteries and they were fine. The batteries themselves were showing 12.6v so they seemed fine too. I also have a battery test unit and that showed both batteries to be 100% fine.
So we came home with no power, which wasn't a deal breaker because I could run the fridge in the car using my Bluetti EB70 for power. Having no lights was inconvenient but we got by with a couple of AAA battery powered LEDs.
Hooking in to power at a caravan park on the way didn't help. The Projecta charger just brought up an error message. The van has a 1240 Redarc for solar and charge from thge car but that was just flashing too, with no power going in to the batteries. The car wasn't providing any charge while on the road either.
Interestingly, a couple of days prior to this, and after being off grid for 48 hours, the fridge in the Tvan wouldn't run. It would start and stop immediately so I used the Bluetti to keep it going. I checked the voltage at the merit plug in the front box and it was 125v so the issue wasn't with the fridge cutting out due to low battery voltage. The next day, after a few hours on the road, it all worked again. We were off grid for another 24 hours with no problem running the fridge from the van batteries.
Some related info: 5YO Firetail, twin AGMs (originals), 1240Redarc BCDC, 1225 Projecta charger.
I can't get the van to Track or an auto elec for a few weeks so I may try checking it out but the question is where to begin. Has anyone got any suggestions as to what might be the problem ?
