Testing Solenoids

Testing Solenoids
I have a question for you guys. I recently installed a nitrous kit on my car with a window switch and wide open throttle switch. I want to test to see if my solenoids are firing before actually even using nitrous, but I want to do it in my garage. The problem is, I hooked up the window switch before testing to see if the solenoids fired. The only way I could think of doing it is to turn the bottle off, increase the throttle to the rpm window I have it set for, and hold the wot switch button in. Now this will fire the fuel solenoid, and nitrous solenoid, but I wont have any nitrous in the line. I will only have actual fuel firing for a split second into the intake manifold, will this work? Thanks

I taped my wot switch down and put the 3000 pill in my window switch. Dont fire fuel or nitrous into the intake. Put the hose in a plastic bag and duct tape it shut. I did this for both solenoids to test them.
Maybe try to put the smallest jets in so theres not as much/nitrous spraying.

Much easier way...
I take it you used a relay with the system, correct? Arm the system, and use a small wire to jumper the low current side of the circuit to a ground - that usually where you wire in all of your safety systems. Doing so will activate the high current side, ie fire the solenoids. Have the bottle closed, and hold a soda bottle over the end of the fuel line to catch what comes out. That's how I tested my noids.

Damn, that metro is going to be SICK with nitrous, lol, j/k.
Check the grounds on the solenoids and make sure they are good. Instead of testing it with the wot/rpm window switch, make sure they are just firing when power is going to them first. I have a push button switch i carry around with wire on it, i just do what NHRATA01 does, put power to the trigger from the battery and check the solenoids fire. Start from small and work your way up, there are too many things that can go wrong when you test from wot/rpm window switch, so just start from the beginning. GL!

Testing solenoids. All I did was have them grounded and run the postive over the POS battery terminal. If you hear clicking, its working. Also what happened to me the very first time, was my 12v relay was shot. Basically disassembled my entire wiring, because it was either that or the window switch. But it was the relay.
To actually make sure the fuel solenoid is working (as in spray fuel) I'd set my window switch to read WOT at a low voltage. Instead of 4.6-.7 i'd have it at 2.5 or something like that. Hold the line to a bucket and push on the throttle body, and if it sprays i am good lol.

Troubleshooting. If you put 12V to the noids and they click, then you know they are ok and wired correctly. If not, either bad noids or bad choice of ground. From there you can start testing the other components. The easiest thing to do is use a multimeter on the ohms setting, and look for a closed circuit on the WOT switch when activated, and then on the window switch when in the correct rpm range. Ohm out your grounds while you're at it too.

You start from the basics, if the solenoids aren't firing AT ALL, why go through the trouble to figure out if its your wot switch, rpm signal, wiring, and go through all that trouble, if the solenoids don't fire directly? If they fire from the start, great, then you know it isn't the solenoid, then you go to the next thing that it could be. Ultimately, you want everything to work, but he is troubleshooting right now. Think of it as a flow chart. Start from the basics.

Apparently, you didn't know to cut the two wires, but it's good you found the problem.
