Rewound rotor on and torqued.New(Mikes XS)brushes installed.Stator remounted.New charged battery in,(12.7)with key not on.When key turned on instantly blows fuse(20a),tried twice.Removed stator to the side,turned key on,doesn’t blow fuse,battery (12.3)when key on.Unquestionably I no to STOP.Not going to ruin a new Jim’s rotor.Going to stay on my initial charging system inspection and component/s replacement plan for this 75b.Its coming apart where needed for easier access to probe properly with my tester and address any problem connectors and wires as I go.Ive read and reread old and recent threads. I almost got in a sloppy rush and over my head to get a traditional Easter ride.The riding can and will wait.I’ll feel better about asking for further advice when I get everything more accessible.Until then,thank-you all and Ride Safe Friends.
