Whelen PCC8R Assistance....

[rmoni317]

Okay I just joined the forums here and this is my first post. Sorry to repeat old threads but my searching didn't turn up with what I actually needed. I just purchased the Whelen PCC8R 8Function Control Relay and I figured out the yellow wire will be what I need to power all my equipment. I was wondering and I did notice someone mention it but not advance on it if you could possibly use one of the switches to power all others. It was mentioned using a diode but I cannot figure it out.


This is what I would like to do:


Switch 1 - Main Power (ALL LIGHTS)


Switch 2 - Front Grille


Switch 3 - Headlight Strobes


Switch 4 - Momentary Air Horn Button


Switch 5 - Rear Flasher


Switch 6 - Rear Warning


Switch 7 - Left Arrow


Switch 8 - Right Arrow


Any help would be greatly appreciated !

I assume you would need diodes in order to be able to power all lights at once, and them power them separately, or else when you power on one light, it would backfeed and power them all.

I have never used diodes so I wouldn't know what to do unless explained a little bit more.. I know someone on here has done it before but it seems they might not be around anymore.

I'll try to keep it simple, as it's hard to illustrate in text form.


The PCC8R has 8 available switching stations, we'll call these 1-8. Now, you have 7 pieces of equipment (or groups of equipment, or whatever else) to be switched by 2-8 and everything will come on with 1. Still with me? We'll call these A-G.


A-G will each have their own wires and those wires will run to 2-8 with a diode placed inline. Also, all the wires will run to 1 with a diode inline for each wire. This will prevent backflow of current to other loads when say switch 4 is selected.
