J.D., In a article submitted by Lee Swanger it mentioned that you had some input on the design of of the tach driven by the vehicle ESS.
I installed identical products as in the article to no avail the tach will bob a little when one turns on the switch recognizing the 12V but thats where it ends it is non responsive to rpm. I e-mailed Lee and he recomended since they are so cheap to replace the transistor.
My question is where can one find info on how they work? I am assuming that it works in this case as a switch. it has Base, Collector and Emitter.I am curious as to the function of each.
Bought a oscilloscope on e-bay today so I can obtain the values from the ESS and compare to his.
Its probably something simple that I'm overlooking at least I hope so. :confused: Thanks in advance.........Merle
