Hello friends. I'm stumped. The bike is an '86 SEi with 26K miles which I bought new. Back in '09 I asked for help with this bike and then life happened. Fast forward 11 years and I am working on it again! All of the pin couplers have been cut out and the connections have been soldered (the three yellow wires in front of the battery box as well as the corresponding connections at the rectifier/regulator). Keep in mind I cannot do any tests without the rectifier in line due to the soldered connections. Upon start up and idle, the volt meter on the bike reads 13+ for a few seconds, then it drops to 11ish. It will go back and forth between the two readings (11-13 sometimes up to 14) while at idle. The lights go dimmer when the volts drops to 11ish as you would expect. If the throttle is cracked while its at 13 volts, the volt meter instantly drops to 11 and stays there while at higher than idle RPM. Similarly if the throttle is cracked while idling at 11 volts it stays at 11 volts. With the bike idling and the meter set to AC, the neg. probe on the neg. battery terminal, positive probe touching each yellow wire one at a time, all three wires give a reading of 7 volts. As soon as the throttle is cracked the meter reads 0.1, or similar on all three wires and stays there until it idles again. When I checked the stator by reading the voltage between yellow wire A to yellow wire B, wire B to wire C, then wire C to wire A, each reading was 12 volts with the bike at idle. As soon as the RPM increased the readings dropped to 1.7ish volts for all three wires. Logic tells me that the stator is good because if it were shorted it would not create 13 or 14 volts at anytime as it has no moving parts. My thought is either its good or its not, but I am wrong several times a day so enlighten me. If you agree the stator is good, do you suspect the rectifier/regulator? What about the black sensor wire on the regulator. I've read that that wire monitors the electrical charging needs of the bike and tells the rectifier what to do. One other thing, the rectifier gets EXTREMELY hot very quickly. I expect it to get hot but this will burn you if you touch it for more than an instant. Is that normal? It gets so hot I would expect the faux gas tank plastic to melt. Any and all thoughts are greatly appreciated!
