I haven't checked voltages, but the battery is new, only 6-8 weeks old, and has loads of power. there is good power at the starter terminals on the inner fender, as when I try to jump the starter directly there w/ needle nose pliers I get a healthy spark, but again all I hear is the glow plug relay switching off. How would I test the started otherwise? It's a holiday monday here, so my resources are pretty limited
