RV Wiring

[patkvm]

Good day all,

I have a quick question that I think I know the answer too. I need to put a refer cooling fan behind my refer, I have no 12 volt source behind the unit so I need to know if it would be safe to run the wires directly to the battery with an in-line fuse to the fan. I just want to make sure that I will not be putting a strain on the charger.

The fan pulls less then 1 amp, it is more in the range of .50 amps.

Thank you in advance for your help.

I will look again but the refer is a Norcold N300 that is 120v and LP. The only wires that are behind it is 120 and it is clearly labeled. there is a nice wire block on the back of the Refer that has 12v terminals but they are empty and dead. There is a chase that the propane hose is in coming through the floor so I wanted to run the wires in there and back to the battery. The trailer is a Jayco Swift SLX 185RB so it is not the top of the line trailer.

Unless this is an old friedge with a pilot light, 2 way fridge needs 12 volts to both operate the gas valve and the igniter along with the inside light and controls etc.

My two way fridge has 12 volts - that's what operates the circuit board and maybe even gas solenoid.

My 2006 Jayco has 12V power behind its fridge. If I remember correctly, its the thick 12V RED wire. I found this wire and traced to its circuit board. It has "+" beside its plug in. I then confirmed ALWAYS LIVE 12V "+" power using 12V probe tester. For my computer fan, I simply connected to this red wire - using inline fuse and manual off/on switch.

I would have thought that there be 12 volts behind the unit but in Jayco's infinite wisdom they only put a 2 way refer in the trailer. So instead of pulling out the refer I thought that I would just run the lead about 3 feet to the battery.

You will be just fine hooking to the battery.

However you probably have 12volts going to the refer control board in back there.
I doubt an extra .5amp would cause any problems. That line is probably fed from one of your 12 fuses in your power distribution panel.
