Got my Nathan P3 in and hooked up but I have a problem. I have a Banks IQ on my truck which looks just like a GPS but gives me readouts on engine temps and preformance. I have my switch hooked up into my fuse panel inside my truck right beside my door. Everytime I flip the switch my screen will freeze. How do I get away from this? I am plugging into two separate ingition fuses so the horn and compressor will only come on when the ignition is turned on…What is the best way to hook up the switch? I don’t want the compressor coming on when the truck is sitting at night or not in use.
Looking at some of the other posts should I just run another line from my battery with another switch to turn it on and off when I get in the truck. But this way I always have to remember to flick the switch… I took out the wires from the fuse panel and the freezing has stopped…Any info is greatly appreciated…
Are u sure the Banks and your toggle switch are on different circuits? Sounds like they may be in the same circuit and when you flip the switch it is affecting the power draw to the Banks. Even if you have them each connected to two different fuses they could be on the same circuit. If your cigarette lighter or another power outlet are switched via the ignition maybe you could tie your switch into that line.
Here’s another thought… Are u using a pressure switch? If not and your toggle goes straight to the compressor then maybe you are drawing too much current for that circuit to handle. The compressor should be connected straight to the battery with an in-line fuse to protect it. A pressure switch doesn’t need much power and should be able to connect to an ignition line no prob.
I do have a pressure switch and will try different ways. I think a separate line to the battery with a toggle to power the switch might be my best bet… any thoughts…
So I looked at it and I have one line that powers on the compressor and one line to activate the switch. I would rather have the power not hooked into the fuse panel because of various reasons. Any thoughts
Both are run to the fuse box? If so, like I said above run the comp to the battery and the toggle switch for the pressure switch to the fuse box. That comp will draw to much start up amps and shouldn’t be connected to the fuse box.
Just to be clear - does your pressure switch have a built in relay? Or are you using a separate relay?
not sure on the relay? got it from hornblasters and i guess it was the heavy duty one…
Is it a gray, blue, or red box with mulitple wires coming out?
If so, the relay is built in.
If the pressure switch only has 2 tabs to hook to - it is only a switch.
Then you have to use a separate relay.
BigYella, this is somewhat incorrect… you don’t want the compressor running to the battery with a fuse… to protect it… you want the compressor running to a relay with a fuse to protect it… ALWAYS use a relay when you are going up in power consumption… doing it this way you will be able to get more power to the compressor safely…
Here is a wiring diagram that I’ve created… This is if you have a built in relay to your pressure switch…
Doh! What was I thinking?! You are right, thanks for correcting me!
Here’s the diagram from HB which is similar to yours:
