12v Fridge Turned On Whilst Traveling Question!

"We counted every corrugation"...OK how many were there!...we want to know too...:))))

7,327.3 from the end of the bitumem out of Derby to Joe's (Jack's) Waterhole where the corrugations shook a kidney stone out of me and I stopped counting......... but that's another story and drama.

Needs another trip to finish off (June this year).

Cheers

If the battery didn't last 20 minutes then there would most likely have been something wrong with it or the charge system of the car. Most caravan 3 way fridges use around 9 to 10 amps continuous so at most it would have consumed 4 amp hours of power, well within the capacity of any starting battery. A Fully charged Falcon battery in servicable condition should be able to run the fridge for at least a couple of hours & still start the engine.
Rather than a relay turning the fridge off completly risking your food & beer getting warm, fitting a low voltage disconnect switch would continue to run the fridge turning it off with sufficient power in the battery to still start. They also have alarms on them to warn you power is getting down.

This is 3 times the cost of the relay solution posted a few times above

What if you want lights/cig socket etc still active while stationary?

Hi
The relay coil is fed from the "IGNITION CIRCUIT " not the acc circuit can still use cig socket /radio etc
