The pups I have are the Kent Armstrong HB5E3B model.
This diagram below is about all i can find for the kent armstrong bass pickup wire colours online and seems correct, their guitar humbucker pickups are different just to confuse.
Have hit up Flynn amps in glasgow who are good at this type of thing, see if they'll help. Losing the will to live, this is my 2nd day dicking about with it.
Might be the jack is wrong, I had to take the jack socket off the new harness as it was the wrong type, mine has a long barrel jack, just wondering if I've done that re-wiring wrong now.
with a voltmeter and the 9v battery plugged in I get near to 9v reading at teh jack terminal for battery wire, I dont however get any voltage reading on the hot terminal that the volume pot is wired to with my amp on and lead plugged in the bass. my logic tells me I should get a voltage reading there. I get voltage readings off the bass and treble pots but not the volume or blend pots. I do get resistance readings off the volume and blend pots though. Not sure of any of that is significant.
Electronics is a bit like double dutch to me, if there isn't a clear wiring diagram to follow I'm struggling.
