When I hit the starter on my CJ-7, the engine will crank but not fire. If i then move the switch from the starter position back to the normal on position the engine will then fire. Some times it runs backwards and some times it runs the right way.
Sometime it works just great.....
I got 225K on the chassis and switch so I'm thinking the switch is going out.
If i am reading the schematic correctly the switch in the starting position will short out the ballast resistor to give full voltage to the coil.
When the switch is in the on position the ballast resistor is back in line with the coil and points.
If it wasn't such a pain in the A$$ to replace I would do it in a heart beat.
Getting too old to lay on my back and my bifocals wont let me see it in focus
