charging

Hello all! Im currently building a chopper from a frame/engine I picked up a few months back, and its going great. Its a 1979. Bike runs great and its tons ogreatly! I had to wire the bike from scratch, as it came with nothing and I've never had a bike like this before. I bought the MikeXS...

My battery was pretty low after not starting it up for a week or two and it’s been a few months since I charged it anyway, to the point where the electric start hadn’t been working for a week or so. I pulled the battery and charged it overnight and electric start and everything worked again, but...

Good morning all, I need help with this one. My 1981 XS 650 is changing what it looks like, 8 volts or so. I thought it was the regulator, so I replaced it, and it's still the same. I then removed the stator and tested it, 0.8 ohms between the 3 white wires, no short to ground. I checked the...

Gday there ladies and gents. I have a question regarding solid state reg/recs. I know there is a lot of threads in relation to this but none quite like the question I have. Recently my XS charge PMA broke a mount and cooked itself. I have a spare standard 70-79 charging system that I was gonna...

Hey all. I need to order a battery for this project ‘73 xs650 I inherited. Is this the stock battery box? And if so, can someone confirm the battery size I need? I mistakenly ordered a Yuasa YB12A-A and that was too big for this compartment.

Hey all, first time poster. I’ll try to include as much detail here as possible but if I leave something out please ask. I’m working on replacing the single unit regulator/rectifier on my 1978 xs650 after my last one failed and overcharged the battery, blowing it up and leaving me stranded on...

I am in need of a stator and stator housing to complete my charging system, I have plans to upgrade in the future. For now due to budget I’d like to stick with stock. 60$ for the stator and housing 60$ for the rotor both reading 5.2 ohms. Worth it ?

Hi all, I just recently picked up a super clean 1980 XS650 special II and am planning to replace the carbs ignition/ charging system and simplify the bike as much as possible. I have already learned a lot from this forum about the aftermarket carb kits and the ignition/ charging (sounds like it...

Okily dokily. I reckon this one could be a record breaker. Not charging. XS650SH 81, but it’s the Australian one so it’s running on points. Oh yeah and separate mechanical regulator and rectifier. It’s as stock as possible. Have read loads, tested loads so let me give you a breakdown. Battery...

Hello, First of all, I am thankful for all the information I have already gotten from XS650 Forum and I plan to continue to support this site and be a good member. My name is Patrick and just got the bike I wanted 40 years. I love it. My plan is to get it reliable and keep it with historic...

Hello all, I previously made a post about my 81xs a few months ago, and talked about the charging issues I had. I took it to a mechanic to have it diagnosed, and was told that the stator went bad, and shorted out the wiring. They told me that I could just get a new stator, and buy a used main...

Hi Guys, Ive been rebuilding my 1980 yamaha 650 xs special 2, and have run into some problems, hoping the much smarter folks here can lend their expertise?? I have a new stator a new reg rectifier, new ignition switch, new stator, and a newer harness which was replaced in 2016 (all from mikes...

Let me preface this thread by saying that I am electrically retarded. I could probably do a top end rebuild without a shop manual or Google or anything, but electrical work just baffles me. I just don't get it. I have a 1981 XS650 with the stock charging system. It's a tracker build, with turn...

Hey everybody. Just recently got my 1983 XS650 SH up and running again with the help of a local shop. Just put a new battery and regulator in but now I’m not seeing the charge I want. Battery started around 13.3 and went to just under (13.27/13.25) with everything off. Accessories on it went to...

This section deals with the '80 and newer A type regulator system. For '79 and earlier bikes, see comment #2. Comment #3 discusses using modern rectifiers. So, I've been getting quiet a few PM's lately about how I wired my reg/rec on the 80SG resto. I know there's a lot of info on this site...

I have a new Ricks Electric stator for sale. I bought it off Parts Unlimited a little while ago but have since decided to go with the PMA set up. Its been sitting and I am now unable to return it. If given the asking price I will also throw in a set of brand new brushes Stator Part# 2111-0198...

I'm hanging out my shingle.... Band of Brothers Rewinding Service is open for business (thanks Bob:D) You can read here all the work that went into getting to this point. Send me your rotor. If it's a serviceable core, I'll rewind it with TEMCo MW0181 22 ga. wire. Run-out will be tested before...

Hi so I finally got my bike charging after 4 months of trial and error. Installed a new Electro Sports 350reg/rec. The bike charges, however the voltage is high. At idle the voltage would range between 13-14V and when revved the voltage would go up to 15.9V. I decided to ride it a couple of...

hey guys so ive got a 79 motor thats been sat outside with out an alternator cover on for a while. to the eye the stator looks alright but wanted to know if theres any way of testing it without the engine running? ive just had 5 months off work after a crash so would rather not be spending any...

Fellow member Daniel Black installed one of these and I quite liked the results. He ran wires into the headlight bucket to power the meter. I was hoping I might find a hook-up right in the dash pod and a little wiring diagram research showed I could. But first, here's the results at idle ...
