Okay awesome thank you! Would the faulty relay be the reason the headlight fuse blows when the key is turned on? Or do I have some other electrical mystery to solve? Also I am guessing I will need to replace that relay with a duplicate, not just any relay?

UPDATE alrighty, so it was plugged in wrong... stupid. The photo below is the gold relay that the stator harness was plugged into. I found the plug with 3 white wires coming off the Reg/rec unit and swapped the plugs around... Now it seems to be charging great so that’s a plus. On the...

Just was doing some more looking online at what that gold unit could be and stumbled across this... which is a blurry photo but I’m 99% sure that is exactly what the plug coming from the stator with the three white wires is plugged into...

It has three whites and a yellow wire all from the same harness going into that gold relay looking unit, which has a rubber holder and everything and fits into the battery box. Looks stock to me. I’ll get a photo today and post it. No wires come out of this unit and head anywhere else which...

UPDATE 10mm spanner magnetizes to the right side engine cover no problem. 3 white wires from stator harness all have 0.6-0.7 Ohm between them in all combinations. Manual says 0.48 Ohms +/-10% at 20dge if I remember right from what I read yesterday. So it would appear I am a bit on the high...

Fantastic I will have a go at that today and post an update. Thanks!

UPDATE I checked the battery voltage again, after watching the full lot of charging system videos on motorcycle MDs youtube channel and knowing a little more about what I was looking for. Before starting: 12.7V Idle: 12.3V 2000RPM 12.2-3V 3000RPM 12.2-3V All this as per my knowledge means a...

Fantastic, that makes sense thank you for the reply and giving me a direction to start working in to solve it. Sadly that direction is the one I am least comfortable in... I will put in some good time online looking into trouble shooting the charging system components and hopefully get...

UPDATE First, once the battery was back 100% charged again this afternoon it fired up after only a few kicks. With the key off the battery had 13.2 V and when it was running it was reading 12.6 V. not sure if this is good or bad. Second, it was running pretty rough, backfiring out of the...

The weather is awful and pouring rain today so I was unable to get out to ride. I did however take the fuel cap off and have a look at it, the rubber seal is very shot so it will need replacing for sure. Am I right in assuming that since this seal was shot it was most likely not sealing anyway...

Thanks for the tip, I would not have thought of something like that. The only "holes" in the tank are for the two petcocks and the filler cap, which I believe is all stock. When I was flushing the tank I do remember that if it was tipped upside down it would leak a bit. Is it possible that it...

I had similar problems with my 750. I got an online manual from here which helped a tonne. http://www.yamahatriples.com/files/5613/2786/4749/Yamaha_XS750_Service_Manual.pdf If you pull the seat/tank you should see the three coils. The cylinders are numbered 1-3 from left to right when sitting...

I have, what is as far as I can tell, a late 78 xs750. I have recently done some basic restoration work in getting it running and ridable... or so I thought. I had it out for a maiden voyage a few days ago and it ran great... for exactly 24kms. At which point it sputtered and died while running...
