A computer fan that blows 100cfm was purchased along with [b]an illuminated 12v dc rocker switch with 3 poles.
I've located the 12v block for the frig in my Scamp, but don't have a clue how to connect the fan and switch to the 12v block.
Oh, I plan to connect a fuse too.
Daniel and Joe forgot about your switch having [b]3 poles
First: look closely at the switch and try to see any markings next to the 3 poles. one should be (power), one should be (ACC), and one should be (ground).
Now look at the 12v block for the frig. there should be two terminals with two wires: one white (ground) and one red (+12v).
Now look at the computer fan. There will be two wires there: one black (ground) and one red (+12v)
If you haven't already done so, disconnect your battery
Make sure the trailer's 110 volt power cord is unplugged also.
Go to the frig's 12v block and find the white (ground) wire. Connect a new white wire of the same size from that point to the switch's ([b]ground) terminal. Then connect another white wire from the switch's same ([b]ground) terminal to the fan's [b]BLACK wire.
Go to the frig's 12v block and find the red (+12v) wire. Connect a new red wire of the same size from that point to one side of your in-line fuse holder. Connect another red wire from the other side of the in-line fuse holder to the switch's ([b]power) terminal. Connect a third red wire from the switch's ([b]ACC) terminal to the fan's RED wire.
Make sure the new switch is off.
Install a fuse into the fuse holder. Reconnect the trailer's battery.
Throw the switch to the on position. The switch should light
and the fan should run.
