I think that was like literally taking a piece of 2x4 (wood) and whacking the side of the pump just enough to nudge the components to cause the 'whirring' sound to click in the motor and turn over ... crazy me .. i was desparate and tried it out .. thankfully one knock was enough to bring me to my senses and re-think the electronics .. a little more investigation and it turned out that the arc burns on both contacts were needing a sanding down .. and by doing so .. it presented proper metal to metal contact as opposed to arc-burn residue to arc-burn residue contact .. which (i guess) did provide sufficient metal surface to metal surface contact for electrical current to go through .. any hoot ... one $2 dollar file saved my >$200 pump!! woo hoo!!
