This thing worked before (last year), now it won't. It had the loops cut when I got it and worked fine. We bypassed the switch & the rest of the system works OK. What is the most likely problem? Ground or is the switch messed up?




I redid the connections, they are good. Then I put a different relay on it, same thing. The full throttle switch is getting power & the MSD is getting power.


Is there a way to see if the solenoids are getting power besides having the engine over 3000 rpms & the micro switch on?


I am really starting to think the MSD is bad. When I started checking the wires, the yellow wire from the MSD was not hooked up to the green of the relay, I thought for sure that was the problem, but nope....

 

sounds like a bad switch to me.

 

Yea, I second that suggestion.
I sent you a PM, feel free to write

 

It was the switch, had to turn off the nitrous manually between shifts, it slowed me down & I won't do it again, but I had to get in the 11s.
