Discussion:
weak spark

I inherited a yale model: GC080LGNGAE085 sn#: B818N02163X
Someone else tore it down, valve work, and put it back together, it would turn over but will not start. Wires have been added and spliced into the system between cng, coil and distributor. I have not touched anything yet, other than inspection and some testing of coil. I am not getting near enough coming out of coil, cant even get batt voltage at distributor. But these spliced wires are jumped straight to ignition switch. A wiring diagram of the ignition would be helpful to trace out and ensure everything is ran like it should be, or any help in setting the system back to where it should be.

Yes, Chevy 4.3 v6 running off cng. Tried looking that up, but any reference I find does not show what I have on the system, plugs are different and such things. I know the wiring that has been ran isn't right. It ran before it got here, ran rough, but it ran. I am not sure if the man who tore it down, did the wiring like it is or if it was like that before.
