Updated design for more reliability. Instead of pushing power directly through the push button and burning up the contacts (yes its rated at 60amps but for some reason I think the push button was still the problem) we decided to make the push button power a second relay to iniciate the crank position on the harness. So far it has improved 10 fold as far as start up reliabiliity and with this new diagram it has, so far, provided us with a 100% first push start-up, as opposed to the previous schematic that was very unpredictable.
hey I'm looking at doing that on my '91 240 and was wondering what the keypad was from?
