Hi Jim,
Could well be an earth problem. First check the battery terminals, the
battery posts must be nice and shiny, and the connections tight. Then check
the battery ground, just under the edge of the tool tray. The main battery
feed goes from the battery , under the car to the starter motor, then in the
engine bay to the jump start termianl assembly. If this has no cover on it,
then the contacts in its connector block may be corroded. Also check all the
ground points in the engine bay.
