That is EXACTLY the explanation I've been looking for. Thank you for that.
I really should've known better but I let internet/forum knowledge get the better of me haha
Ok, a little update!
I got the rectifier and regulator, mounted them on a plate to go where the original combined unit would mount and the bike fired up first kick with ease.
sitting around 13.6v at a bit higher than idle... (sorry I have no tach haha) but I'm confident that it is fixed.
I'm...
Alright you've twisted my arm!
I've attached the Wiring Diagram to reflect the addition of the Bosch RE55 just for those playing at home.
I'm also going to order this rectifier. Hopefully have it back on the road by the end of the week providing all the parts come together.
And just to clarify...
*Mac must have deleted his question*
The headlights are switched and are a pair of 21W bulbs. They are always off when starting.
I've decided I'm going to replace the regulator and rectifier as I don't think my issue comes from stator or rotor.
The "DIY" setup that is mentioned all through the...
5twins, I appreciate the reply, but I don't really want to throw more money at anything before I understand what's wrong!
I'm happy to build the regulator and rectifier setup, but it's the principle. I also wonder if the "DIY" reg/rec is applicable to lithium batteries...
Some further results from this morning's testing:
Slap test is fine - can hold a screwdriver or spanner to it and it pulls it in quickly.
Stator resistance wires against housing are infinite.
Double checked stator wires against each other, still 0.5ohms.
With everything plugged in and measuring...
Without derailing my investigation into this issue haha, I don't think it's a matter of keeping their websites up to date as they've probably never been correct in the beginning; aligns with their narrative.
I think it's laziness and poor attention to detail. I daresay that those instructions...
My regulator has a totally different body than that and the wires that correspond with the original harness.
It also came with two plugs like the 70-79 pictured, just not with those coloured wires.
Mine looks identical to this one here.
Just as an aside... I think it's strange that Mike's XS...
Just for posterity I've included the wiring diagram I am using.
I've continued testing today, still getting interesting results.
I've now decided to use a known, good working car battery for testing purposes.
If Stator plug and Points are unplugged, I get no voltage drop with Key On. If either...
I couldn't help myself... that continuity thing was bugging me but I think I made sense of that in my head.
The Rotor is a coil and each copper ring are the ends of the coil... duh haha
Here are some further tests:
Key Off 12.22V at battery
Drops to 12V with key on
Brown ignition wire with key...
Hey Leo,
I understand how the rectifier and regulator work, it's actually a pretty cool system for something on an old bike!
Spare battery was sitting around 11.8v before I hooked it up (have it on tender now)
What I'm still not sure about is the continuity between the brushes...
I get...
Hey Leo!
Thanks for the reply.
I hooked up a spare 12v motorcycle battery and fired the bike up albeit wasn't it's normal one kick.
Strangely, the battery initially read 13.5v and then dropped to 12.6v after a few slight revs.
The bike also was back firing as I revved it, which it never does...
I've been having an issue with my charging system for some time now, I will try to explain as succinctly as possible as there have been a few changes etc along the way.
I bought this bike relatively stock and only changed out the regulator and rectifier from mechanical ones as I was riding once...
Hey guys,
I’m looking for a project that someone has either given up on or a basket case.
Whatever you’ve got, I’d love to see!
Located in Brisbane, Australia.
Thanks in advance!
