Just wanted to start off and say that I am new to this thread. I picked up a 77 cb550k that I am currently building into a brat style bike. With this being said, I am going after the clean look with intentions of clearing out everything behind the side covers and into a battery/electrical tray. On these bikes, they came from the factory with a regulator seperate from the rectifier. I'd like to switch over to a solid state rec. to minimize the things in the tray. I understand that there are new aftermarket solid state recs. (aka rick's). I was at a swap meet the other day and managed to pick up a box of solid state rectifiers, starter solenoids, a bunch of wiring/fuses, etc. for only 2 bucks! I was wondering if there is any way of seeing if these will work. One of them seems to have the same amount of wires that lead into them. Is there anyway of knowing if they will work? I don't know much about them, do these have different amount of volts/amps or anything that I should know about?
