circuts
Sorry ! The Red wire on the relay should be live 12 volts constantly and the red/white has 12 volts when cranking only. With the red and red/white wires disconnected off of the relay use a screwdriver and touch both relay terminals togther WARNING STARTER WILL ENGAGE AND TURN MOTOR this will eliminate the key circut on the sled and isolate electronics, if the fuse blows again disconnect starter and touch terminals if fuse blows relay is faulty. if it is fine reconnect both wires with key in off position, if fuse is still good turn key to RUN position and MANUALLY with starter rope start engine, if fuse is good disconnect red/white wire and with ohm meter with one lead to ground on engine and the other to red/white should have no continuity, if it shows continuity crank red/white circut is defective which you will have to remove key assy. Hope this helps You can check it any sequence this way was where my head was at. Also make sure starter wires are the proper guage thickness for resistance and securely attached .
