Automotive Refrigeration: Part Deux

While getting more specific about the installation, I’ve revised the circuit as shown:

circuit

There are, in fact, two Coleman powered coolers in the back of the vehicle. Currently, one of them is plugged into a 12 VDC outlet in the cargo area; the other is plugged into a power socket on the console (snaking the cord under the back seats). The new circuit provides local power connections for the refrigerators, and includes a voltage display so the charge of the deep cycle battery can be checked.

Qty Price Desc Source Specs
1 $129.00 Trojan 27TMX deep cycle battery Battery Systems 27TMX
1 $84.50 Automatic isolation switch PowerStream
1 $30.14 LCD voltage display 6-18 VDC DigiKey PDF
2 $2.66 Automotive power socket, panel mount w/ lock nut DigiKey PDF
1 $2.55 Automotive power plug, internal screw terminals DigiKey PDF
1 $6.11 6-stud (#10-32) junction block 30A Wiring Products
1 $5.04 16 ga. crimp ring terminal Wiring Products
2 $5.75 16 ga. stranded wire Wiring Products

At a cost of $274.16, it’s a bit pricey. It beats having a dead battery every morning though.
