Hi Bryanj,my battery was pretty low when i went down to the bike this morning,it was reading 11.88 at the battery and 11.18 at the black source wire so i`ll have to charge battery to get a true reading.on a brighter note,i found that one of the yellow wires and a red  wire on the sub harness was half melted,these wires are very flimsy thin wires so i rewired using a heavier gauge wire,i did all 3 yellow wires,both red and green wires on the subharness and set regulator to give out 13 volts,none of the wires are overheating so i`ll see if i can set reg at 13.70/80 without wires overheating and i`ll be happy at that running with lights on.

Bryanj:
When the battery is charged test for battery voltage at the white wire to field winding, should be same as black at reg and batt pos, ignition on and kill switch off, again white wire should be within 0.5 v of battery.
Report back

Bryanj,put battery on a quick charge this morning while i did other things,got it into the bike and ignition sw on,kill sw off,lights off and i got 12.69 volts at live battery,12.69 at black source wire and 12.69 at reg terminal the white wire connects to.Once i connected the white wire i got 11.58 at both the black and white terminals and a decent spark too at the white terminal as the wire came into contact with it.i went for run about for a few local miles and wires are only slightly warm as opposed to what they were like before i changed them.
i`d like to know what that green electrical bar is thats connected to the regulator,that fair gets warm!  i take it i hope that thats normal for that?
