If it's a coil, its AC voltage will be proportional to rotational speed tho it may peak at some value.

Ok I am not having much success with this. I have already installed a
Zemco model 14 on this thing and all it would do was engage and start to over rev and then kick out.So I figured that kit was probably made in the mid 80's and from sitting around was maybe defective.
So I ordered up just the servo for the ccs-100, because I already had
all the wiring , pick-up coil , and switch in place.It acts the same way!
I'm just concerned about the switch. It has a slide button for on -off.
Three other momentary push buttons. set-increase,resume-decrease, and coast. I can get 12 volts on the set and coast buttons but nothing on the resume. Also there are two little lamps inside the casing ,between the switches ,that barley light up until another green wire is grounded.I did use the coast button , in place for the resume.
Does it sound like I need a new switch?

Ok still not having any success. Using the coil only and still the unit only wants to engage and then rev up and disengage.I might add the red power led is not on all the time, just comes on momentary when I push the set button. Should it be on all the time?
Also pin 10 is for the tach and I would assume I should be getting a negative voltage from the coil. Does that sound right. Can anybody tell me what wire off the ECM I could tap into in order to try that route. It is a 1996 geo metro , with the 1.0 engine
I did swap out the push button switch for the set and resume , and now I have the proper voltage on those inputs.
Thanks Rick

Something I may have overlooked, the on/off switch I have is not a momentary one,so when on it is always 12 volt. Looking at the switch online that comes when you buy the whole kit, looks like it is a momentary. So when you press on , it would give a 12 volt signal ,and
off maybe should be a ground to shut it off?
