Ive had a msd switch on my setup for a little over a year now. My problem is I think it **** it self. Not too sure yet because my test light is broken. I went to use my spray the other day against a zo6, I turned on the bottle, armed the system, purged the system, and then hit in second at about 3500ish and nothing happend I was like WTF? I guess the only thing left is to test everything with a test light. The main reason i think its the window switch is because it does occasionaly get wet from cleaning the engine bay or just from driving in the bad weather. Has anyone else had this problem. Any help is appreciated.

 

Have you taken it out of the loop to see if everything else works as it should at WOT?

 

if you are using a WOT switch, jumper the pins on the relay to bypass the switch, just make sure you're at a safe rpm before gettin on it

 

I got rid of my Msd window switch, for many of reasons, get rid of it. The ZEx Traction control Window Switch is alot nicer and easy to mount inside your car, this way you won't have to worry about getting it wet.
