Fridge probs

[Chefpatrol]

Hi guys just wondering if anyone can help. I recently put a 65L dz waeco fridge into my 2004 GU I'm running duel batteries. But my problem is that after I turn the engine off the fridge only runs for a few hours the switches off for example the fridge runs fine all day on the way to camp but will switch itself off during the night. Anyone have any thought or suggestions. Thanks

Maybe you need to set the battery monitor to "Low" See section 6.4 in the Manual

Thanks TimE have tried this but same thing.

How old is your second bat? I'd be thinking it's not holding charge any more. It could also be voltage drop over the cable run from front to back, in which case what TimE said would work or heavier cable.

Thank you Lemo79. I had though it might have been the cable. The bat is about 4 years.

Thank you Lemo79. I had though it might have been the cable. The bat is about 4 years.

get it load tested by an auto sparky but i would say its due for replacement.

As soon as I saw this I said its a Waeco, I'd put a multimeter over your battery it could be on the way out.
does it have a red light flashing at all ?
EDIT:: if the battery is 4 YO I'd seriously think about a replacement.
also how old is your start battery

What size wire did you run from battery to fridge??

[Dales300exc]

Using as a dual zone or fridge only?

I have the cfx65 normal running off a single start battery, get a couple of days without starting out of it in 25-30 degree ambient with fridge them at 0degrees on the display.

Most likely a battery issue.

Fridge only. As for wire size I'm not to sure. Would just like to thank everyone who have responded to my post. I only joint this forum today it already feels like you are all such a great bunch.
