Yes I agree, I’ll have to look for the correct schematic.

Simon, I’m still trying to get a correct schematic but I just had a quick question for you. Is it possible that the grounds for some of these relays is actually sent through an ECU?

I recall seeing the grounds going to frame only, or strap. Sometimes it is the flat braided style, sometimes it is welding cable style.Simon, I’m still trying to get a correct schematic but I just had a quick question for you.

Yeah there are a couple big grounds going to frame. They are all good. Just no ground to the starter, ignition, and LPG relay coils. I tapped in a ground to the LPG relay and Ignition relays. Didn’t have to worry about the starter because it looks like the starter and Ignition relay share a ground. It’s working. Starts and runs normally but someday I would like to get to the source of the issue and understand what it was that has been giving me this huge headache

Will tell you later today how to properly test some of the poor connections that I know are happening.
Just on my way out for 1/2 the day.
