Hello folks, I am hoping someone with more knowledge of the electrical system of an 03 shadow ace vt750cda than I do might have any ideas. I was washing it up and doing a switch check afterwards. When I blew the horn, the horn blew fine then everything died. Noticed the ground terminal was loose, figured I found the problem and tightened it down. Voltage across the battery terminals reads 12.5 with ignition switch off, with ignition switch on they read zero volts. No power anywhere, no lights nothing. Checked master fuse and all fuses in the fuse box, all fuses fine. During the summer the neutral safety switch stopped working, everything was fine with kick stand up and clutch in, so had not replaced it yet. Did a continuity check across the battery leads with battery disconnected. Open with ignition switch off, shorted with ignition switch on. I was confused why there was no heat, sparks or smoke as based on my steps taken so far it appears the battery leads are shorted together with ignition switch on. If this is correct my master fuse should be blown but it is good. I'm scratching my head over here and hoping someone might have some suggestions or ideas.
