I happen to have a MSD WS with Adjustable pills, but I dont know how to check the rpm they are adjusted too? Anyway to do this, other than trial and error?

 

with a multimeter set to DC volts, as you rev the engine see where the switch closes and opens. the use a fine-tipped sharpie to mark the pills. thats one reason i don't like those kinds of switches under the hood. the adhesive thaat holds the little rpm label can get hot and the sticker fall off. those types of switches are better off mounted inside the car, IMO.

 

My pills are embossed and the R.P.M. #s are painted black not labels? Mine were from Summit So don't know.

i think its' 100o ohms for rpm

4000 rpms = 4000 ohms

 

thats the non adjustable ones, I wish there was enough room to label them, **** make my life easier.

 

Ok better, missed that adjustable. I read it, but it was consumed by alcohol.
Before my brain could step in.

Here's how I check mine. See the two green lights, they are wired into the postive wire going to each stage's noids. Top green is 1st stg, bottom green is 2nd stage (haven't stuck 3rd stg in yet). So anytime system is armed the lights come on at selected rpm for each stage. Also, I have qiuck dissconnects on noids, so then I can unplug noids and check system operation without spraying cause lights still get 12v that go to noids. Cat, you must have the adjustable rheostat type. I have the plug type and just watch tach and light at same time, I always know if system is working correctly or not.

I'm not really sure, I know its an MSD box, and both pills are adjustable. I picked this up from Noyzee, that and his old clear lid, 5177, opener, and a grip of other stuff. Instructions he was going to provide, but I lazied on him and wanted to do it later. Now the time is come for me to figure out how to utilize this WS for either the 2nd or 3rd stage Thinking I might just add one of those new dual sided switches from either NX or HSW, something to set up different stages and stuff. Ultimately I want to launch on 150'ish, then hit 100, then follow up with the last 100. Not sure where (rpm) wise. Need to think this one out...
