NPP Stealth mode - added factory & wild modes
 
2 Attachment(s)
although probably not a common occurrence, i wanted to have the dual mode exhaust closed at idle. i came up with the attached fix. there are many ways to skin this cat, i chose this one because it worked for my needs and thought others could get some ideas from it.



There have been several posts looking for a method to have three NPP modes incorporated into a single switch.
Stealth – exhaust flappers closed all the time
Factory – flappers operate as per the factory parameters (more below)
Wild – flappers always open

I created a second DIY to show one way to do it

Sweet, now I really want to do this. There is nothing more to want for this mod... Thanks again man.

I wish I was more electrically adept

Agreed, this is so awesome but I have no electrical knowledge or comfort. Sadly I think I will stll end up dropping $200 for the ADM controller, and will only have 2 functions.

Alternate Method

Hey, I don't mean to put you down, you did a great job figuring that out and it will work perfectly that way, but there is a much simpler way to accomplish this.

You can cut the blue/yellow wire going to the rear fuse block, and wire in an on/off/on rocker switch. Here is a crude diagram of how I wired my NPP.

When you're done, the 3 positions will be flaps Closed/Open/Normal.

Brilliant!
i did not think of that method, much cleaner.

Firefighter 04-16-2014 08:31 AM

Okay... so my electrical experience is limited but how does this last method work? You have one wire that you interrupt. I assume you cut it then a three position switch with an extra ground... how's that make this happen?

If it works I'm all for it b/c cheap and easy. I would like to understand it more though.

UNMODIFIED: When the controller is energized it grounds the valve relay to close the exhaust.
Inferno1LE's mod: position 1 acts like factory, position 2 opens the wire so the relay stays open, position 3 connects the relay to ground.....putting the relay on all the time

Sweet & simple solution. Kinda embarrassed that I didn't think of it

Sometimes we get so involved in our original idea we forget to think of another path.

So verdict is both methods work?

Yep
They should both work............ Simple or Goldberg method-->same result
