The positive battery terminal was on the right side and went to the frame ground post. I actually hooked the battery charger negative to the grounded post(which was actually the Pos. Post). Again this got it started.
I got him a NEW battery, charged it normally and he hooked it up correctly,NEG to ground, and got nothing. When he reversed the battery and put POS to ground, he got horn, lights and a running bike.
I haven't run across this before, so what's up with this scenerio, and what does he need to do to correct it? This is a normal 47 era WL Flathead.
