Zex purge problem... I am pretty new here, been reading for a while to get a 101 on nitrous!! Anyhow, I have an 03 Z06 h/c w/100 Zex wet kit. My system will not purge. I checked the switch to see if it was bad, it's not, the noid clicks when I hit the switch. I thought maybe the noids were stuck, so I ran a hotwire from the battery, touched the wire on the purge and it worked/purged fine, so the purge noid is not stuck. I bought the car with the nitrous system on it, I cannot find any fuses or anything, I thought maybe it was a bad fuse. It also has a NX switch. So I bought a cheapo toggle to try that, still got a click when I flipped the toggle.
Could it be a problem with the Zex system(purple box) that everthing runs in/out of? Sorry for the noob questions, but I am at a loss here. Anyone have any info/ideas? Let me know...thanks!!!

I agree i would check the ground, my zex kit is very tempermental and has to have a perfect ground in order to work, and i would check the main power going to the solenoids as well to make sure its a constant 12v feed because it sounds like it might be losing power through the wiring that you have set up, or your power wire might be touching a ground and make sure nothing is sharing the circut

How did you test the wire going from the purge solenoid to the box?
I would start checking for voltage/grounds on the terminals at the box now. I'm not familiar with the Zex "box" in particular, but all systems do basically the same thing. Does the box store the relays internally?
Just keep going further down the line, you'll find the problem somewhere.

Do you know if there is a relay on the purge solenoid? And then a momentary button to activate the relay that turns the purge solenoid on?

hey I had the same problem with the ZEX selenoids, not only was the NMU selenoid fried, but the Purge too. Do a bench test of your Solenoid, hook it to a 12V powersource, if you hear a click, it works, if not, contact Nitrousoutlet.com for a better solenoid.

When I run a hot wire from the battery it purges.
When I run a wire from the wire on the purge to the switch, and I flip the switch, it purges. So...there is a short somewhere in the existing wiring, I can't find it!! Remind you, I did not wire the car.
Could I cut the existing wire running to the purge, and run a new wire from the purge noid to my NX switch (that is a keyed power source) and put a relay in the new wire with a 5 amp fuse? Someone let me know if that will work. I am sick of searching and really want to use my system, but not to the jeopardy of starting an electrical fire!! Let me know, thanks!!

I thought that too. However, everything hooked to that switch as well works. The power wire comes over from my arming switch and bottle heater, both of those work, also on there is my bottle opener which also works. With these other accessories working is why I was so stumped as to why the purge would not.
StngKlr...So running a new wire would work??

My Zex kit has a 15 amp fuse in the purge.

When I leave the cross wire from the 1st switch arced to #2 and run a new wire from #2(purge) directly to the wire running out of the noid, it purges fine when the switch is pressed. So the switch is good. Would you suggest running a new wire like mentioned above? Thanks for the help!!!

Sounds like he put the fuse in the circuit from the switch to the purge (which is not where the instruction said to). I'm weak on electricty so I can't advise on the wire (other than saying make sure it's fused). The only reason I knew what I did was because I just put the same kit in my Z06 except with the nitrous outlet switch panel and I had previously put one (Zex) in my WS6.

Anyone else want to let me know if it would be alright to cut my current wires and run a new one with a fuse???
If it were me I'd run the purge on a seperate circuit and/or relay altogether, just because if you were to ever have a problem down the road it would be eaiser to diagnose and fix, rather than going through this allover again. A didital volt meter has always been my best friend when it comes to wiring, did you get one yet? This is about as basic as it gets when it comes to DIY wiring, I think you will get it figured out. Let us know.
