So I recently bought a solid state Electrosport ESR350 (has the two plugs) reg/rec for my 1979 xs650.
Everything in my charging system is stock 1979 stuff (so from what I understand I should not need nylon screws). The wires on the two plugs are as follows: the rectifier portion has 3-whites, 1-black, and 1-red. The regulator portion of the plug plug has 1-brown and 1-green wire. According to Electrosport, this reg/rec should be "plug and play" with my stock charging system. Plug and play my ass.
So anyways when I "plugged and played" it, I got no charge whatsoever. After messing around with it for a while, I removed the reg/rec's red and black wires from the one plug so that the only wires that were in that plug connected to the stock plug were the 3-whites. I then ran a jumper from the reg/rec's red wire directly to the positve battery terminal and then ran a jumper from the reg/rec's black wire directly to ground. Still nothing.
So then, I disconnected the reg/rec's black wire that I ran directly to ground and just let it hang in the air so it wasn't being used. I left the reg/rec's red wire still jumpered and connected directly from the reg/rec to the positive battery terminal. I started the bike and now it is charging.
Meanwhile during all of the this, the reg/rec's regulator plug (brown and green wires) were connected to the stock wiring harness like they should be. Now with the current wire configuration and the battery charging, when I rev up the rpms to like the 4000 rpm mark, the battery voltage will keep climbing higher and higher to the point where I hit 15 volts on the battery so I stopped.
My question is: does anyone know, from what I explained above, why I'm having to leave the new reg/rec's black wire not connected to anything to get a charge? And also what is the highest voltage the regulator should allow the battery voltage to charge to before it kicks in and starts regulating how much voltage the battery receives from the charging system?
