I recently had the wires soldered at the back of the master switch come loose due to corrosion and strand me on the side of the road, so I get home find the problem and wire in a single pole double throw switch according to the wiring diagram so I still have the same function as the old master switch. BUT upon riding the bike again I lost the charging circuit and got stranded again so I installed a new stator and voltage regulator/rectifier made by electrosport and when I fired the bike up it was charging 13.8 volts DC but as soon as I had the bike warmed up I checked again and now only had 11.7 VDC , so I check the stator and it is putting out 28.9 volts AC on each leg or yellow wire coming from the stator at around 4000 rpm. But I still have only 11.8 VDC at the battery, so I buy another regulator/rectifier but no change still 11.8 at the batt? By the way the bike is a 1979 KZ1300A1 all stock except for Nology coils,NGK wires,D&G six into one pipe and now the Electrosport charging stator an reg/rec. My question is how is the master switch wired internaly because this all stated when it crapped out , what the heck am I missing here. Thanks Mike in Tennessee USA.
