Question on testing nitrous wiring
Question on testing nitrous wiring On my second try at getting the nitrous working. I got a little to complex with my wiring job last time and going a simpler route this time. I've got the bare min hooked up right now. I have a FPSS and a window switch, but they have all been bypassed. I'm just trying to make sure I have the basics working fine and then will wire in the other stuff. I hooked up everything to a switch and when I hit the wot switch I hear a click, which is a good sign. However, from what I have read, I think both the nitrous and fuel silenoid should be clicking. I've put my ear up to both, and neither are clicking. However, the relay is clicking when the wot switch is depressed. Is this how it should be, or should the silenoids themselves be clicking? If they should, does anyone know what the problem might be? I'll be sure to check all the wiring of the silenoids themsleves in the morning if they should be clicking. But figured someone on here might have run into same problem and be able to give me a little insight.

Re: Question on testing nitrous wiring Sounds like a problem with the solenoid grounds. Do you have a volt meter? That would make things 100x easier to diagnose. Also, is your wire which goes to the FPSS (white on NX relays) grounded or not?
Re: Question on testing nitrous wiring Yes, I do have a volt meter. And I have grounded the wire that is suppose to go to my fpss. I'm gonna go out there in a bit and see if I can't find the problem.
Re: Question on testing nitrous wiring Ebery thing works now 
. Guess it would help if the relay had power, doh 
Last night when I hooked up the power, I thought I had traced the correct wire from relay to battery, but guess not. I had the bottle heater hooked up, not the relay wire. Omce I started using volt meter I knew something was up. No power to relay from battery. Then I noticed the wire coming out from relay had a fuse inline right near the relay. That's wierd, because the wire which I thought was for the relay and was hooked up, had a fuse right near the battery. That is when it clicked. And thankfully now, everything else is clicking too. Well, time to drop the bottle off to get filled and finish up with bottle heater and purge.
