Don't forget to check the physical ground cables by feeling for sponginess.
My Spit had a similar problem a few years ago. Continuity and resistance
where it should be. Hit the started and everything would die until moving
the ground cable around. The ground cable was clean on both ends, no
corrosion at the terminal ends. A section in the middle was corroded, felt
like sand under the insulation.

Tim,
I would start out with the 2 primary ground connections, the one from
the battery to the firewall and the 2nd from the left front of the
engine to the frame. Insure connections are clean and tight. You should
have metal on metal. When I did my 4 a few years back, I soldered a
copper washer to the firewall where the ground attaches. I always insure
it as well as the cable end are bright and shinny. The ground on the
engine and frame should be metal to metal, no grease, paint etc.
Then I would look at the battery connection to the solenoid. Same there,
clean and tight. Third the Lucar connections on the solenoid itself.
They may be oxidized from higher than normal current flows. Also they
should be very tight. You might have to squeeze them a bit. The wire
that runs the solenoid (white / red I believe) may be the problem.
Then inspect the cable from the solenoid to the starter. Same procedure,
clean and tight.
The only thing left is the starter ground itself. If all else fails,
remove the starter and clean with a wire brush down to the metal the
area where the starter attaches to the engine block and the starter
itself. Right down to bare metal.
Good luck.
Bob
