ok ... I've jumped the grounds and the (+) battery to (+) starter (again) and that doesn't make her spin any faster ... Until a few minutes ago I thought that's all an IDI needed ... fuel and rotation ... am I wrong?
GP system has fewer than 150 hours of service ... plugs are clean (just had them out) and yes sir ... I can hear the controller.
I've never had an issue with Optima Reds ... it doesn't get cold here so they crank out 1000 amps each ... and I have a gear reduction starter ... I really don't think "spin" is the problem ... can't think of anything else though.
