I have a travel trailer and I would like an alarm in my truck if my fridge loses 12v power while driving.
I thought about running a cable from the last junction to the fridge, showing a light if all is good but an audible alarm on power loss would be better.
So perhaps something with a small rechargeable battery in it that fires off if it loses 12v?
The low voltage alarms aren’t relevant because they don’t work if voltage goes from good to zero, right? Like if a fuse blows or some such.
