Hey guys, newbie here trying his best
I've been working on the charging system for my '77 xs360 here for a while and still haven't been able to figure out why when the bike is running I can't get the 14.5v across the battery. Mad props to the guys on here that show so much detail on checking your stator and replacing the wiring for the charging system.
So my issue started when my old battery died while I was idling in traffic, figured it was my charging system so I started with the rectifier and regulator. I couldn't get the correct continuity as the manual explained through the rectifier so I since have replaced with a combo rectifier / regulator....twice. I have also gotten a new maintenance free battery.
I have gone through checking the stator and coils, I have measured 0.8, 0.8, and 0.9 across the white wires (this is with a little corrosion on the plugs and a 0.1 tolerance on my multimeter). The coil and wires are surprisingly in good condition (there is only ~6500 miles on the bike if that means anything to you)
The first combo (cant remember the model, got it off amazon) appeared to work, although the regulator part I was skeptical about. After riding for while with no issues thought I was good, but then it blew up on me; over heated and broke the main fuse.
The second combo (RR38) has me a little confused; with the bike running I only measure what the battery is currently charged to, 12.8v, and still do not get the 14.5v. Everywhere I measure on the bike to check voltage (horn, flasher relay, rectifier, etc.) I get 12.8v. I haven't taken the bike out since cause I don't want it breaking down on me again in traffic.
Do yall have any suggestions on where I need to look next? I feel like I've done everything, but rewire the entire bike. Is it possible that even though the coils looked clean they are bad, or that I could be dumping the extra voltage off on the ground of the bike?
