OK - so if you switched on emergency mode and fridge was off in the morning - I suspect the capacity left in your aux battery.
Unless you were parked in full sun all day in say, Darwin - without car being run or charged... then I doubt it would also last overnight!
I had my CF 50 run for two nights and one day with no issues, at the tip of Cape York in September. Also used all of our LED lights on both nights. We didn't drive the car for one day due to visiting Thursday Island for the day.
The low voltage cutout is particularly sensitive to the wiring between the battery and the fridge. The 10.5V cutout is measured at the Fridge when the compressor is running and I had problems with the fridge cutting out when it was connected directly to my old Patrol's second battery in the back via a cheap cigarette lighter plug and cable. Put a decent cable in and no problems from then on. Traxide cables are fine though!
The entire circuit is cutting out so I think the problems outside of the fridge cutout.

The only thing I can think of is that the SC80 is wired incorrectly and is between the load circuit and the second battery, instead of between the second battery and the starter battery. This would mean that your circuits from the second battery are cut when the voltage falls below the cutoff voltage instead of just the battery being isolated from the starter battery.
Ah ok, I always assumed it behaved differently. In that case I definitely have a problem. I followed Tims instructions to the letter so I don't really know where to start fault checking it.Quote:

Just check that the isolator has a red wire going to the main battery positive and a red wire going to the second battery positive. The load circuit is connected straight to the positive on the second battery via a fuse. You may have mixed up the wiring at one end perhaps?
I forgot to mention i've also got an ABG-25 at the back.
I've managed to replicate it and that's the cause of the issue: 12.4v on the battery side of it, on the other nothing. Short quick flashes so it sounds like it's activated it's cut out, but it's not meant to cut out at that high a voltage so I'm assuming it's faulty...
Hi Ben, the ABG-25 should not Cut-Out above 11.6v, unless the voltage settings have been changed.
If you did not change the settings, then check the connections to see if there is a loose negative connection.
A loose negative connection can cause the unit to Cut-Out at a higher voltage.
No worries, i'll remove it and re-fit and let you know what happens. Cheers!Quote:
