rectifier regulator

New Owner of an old 1980 XS400. Brought her home and I couldn't help but start troubleshooting before work. I replaced the spark plugs, gave it a kick-start but no dice. Pulled the spark plugs and tested the spark. No spark. I'm assuming it's a either the battery, the regulator rectifier, or...

Heylo. The skinny: I built a cafe racer, eitrd from scratch, burnt out two batteries. I have a combo reg/rec purchased from Ricks. My bike is a 1981 xs400 heritage special. My R.R has 3 white wires, which I ran to the white wires on the R.R, 1 green to the magnet? A brown wire that...

Hey guys, will this charging diagram part of my system work? I am SO LOST, but feel like I'm getting close to grasping.

So I was riding on my bike's longest ride to date and she died while on the highway. Thankfully I had a buddy of mine following because the reason she died is that my rectifier had flew off :yikes: (long story ), but he found it on the side of the road :D. When it did fly off it ripped the...

Hey there, just got a 400 maxim a few days ago. I got it running, the battery was dead, only putting out 10 volts. I'd try to turn it over, and something made a clicking noise? (A box behind the battery), some sort of voltage regulator? Anyways...plugged it into a charger and put it on 12V jump...

Hello, I'm new ad this is my first post. I have an 81 xs400. It generates no charge so when it's running it dies after about ten miles. I (regretfully) took it to a shop that told me the reg/rec were shot. They replaced with 2 in 1 unit marked tmr1003bu. After this they decide stator is shot...
