I have had the msd window switch modified for a one cylinder application. I bought autometer rpm pills because that is all I could find on summitracing. I did not try a run with nitrous because my bottle is empty. Now when I tested it with GarthG, the car no longer has that 'twong' sound it had before the switch when it was activated. Can anyone give me any suggestions? Are these autometer rpm pills not compatible with the msd rpm window switch?

 

Tell us how you wired it?

 

Took switched power and hooked it to the red (checked to make sure it turns on and off with switch)

Ground Wire hooked to the battery (assume grounded correctly as everything else in the car works perfectly)

Took the lead that needed a pulse and hooked it to purple w/white stripe wire on cyl 4 (as that was easiest and I don't think it should matter which cylinder as it just needs a pulse.) (Looks to be pulsing correctly)

The 1.5 Amp max out went to where the switched power used to go. (can't check if it is turning on any ideas on testing would be great on how to check this).

 

Please help. I don't want to blow up my car because this thing isn't working

 

you don't have to worry about that....if it's not "working" then your nitrous won't activate at all unless you bypass the Window switch...

 

Bottles are for babies

 

Can we please try and keep this topic free from comments like this. . . Some memebers choose to use nitrous, some don't. . . If you don't know anything about this please stay out of the thread. Thanks.

 

 

I am a baby. I love bottles. Now, can anyone help?

 

Geez. Maybe I should have written the word TURBO just to get people to look at it

 

I finally read what Garth G wrote...i didn't know he was working on this with you. The yellow wire DOES NOT provide +12V...so that's your problem. It's not suppose to give +12V switched power. Look at Figure 5, from the MSD installation instruction. The yellow suppose to provide switched "GROUND". Hook the yellow wire to the ground of your main nitrous relay.

 

gah gah goo goo


no need to hate...........heheh j/k

 

Thank you for an answer. . . I should have read it more carefully. That is where the problem is.
