My cb750 scrambler build. Restart

I'll get the grey matter looking at it again tomorrow. I'll be sure to put it out there when I do. ( never thought of the the heat from the regulator)

Ok so I've made a bracket and welded it to the side of the battery box for the regulator. What do you think?
With it like this I've got a load of room now for the m-unit and the wiring so that's made it an easy way to lift the tray to access the battery.

It should get an adequate cooling draught by there.

Thanks Mike That's good news. I never thought about it to Yozzer pointed  it out. As a result it's actually turned out a better idea.

It's the same position as my GS650G, so it'll be fine.

Well now the real fun begins.
Original wiring from battery backs is in really good nick but the front part......wtf!

Need help already. So I bought a new solid state regulator from m&p (picture below). All the diagrams I can find show dohc regulator retro fitted.  Can anyone help. I'm scratching my head.
Thanks.

3 x yellows are the ac windings on the alternator.   Red and green are the pos and neg to the batt.  The black and grey (white?) go the inside coil of the alternator,  the excitor winding.

Hope this helps.

You won't be using any of the old harness will you ??

Hi Mike. Thanks for the reply. It's the black and white that I'm stuck with. Is there a diagram to explain what your saying as I'm still a bit lost. I got in touch with the manufacturer and they sent me this.
Red. Positive
Green. Ground
Yellow. Stator
Black. Original sence input for regulator
White. Field output for alternator

Hi Yozzer, nope it's all going. Completely new.

Dunno what the original sense input is, sorry.

Hi Mike, thanks anyway. I'm going to email them again and ask them to send me a diagram.

This is the last email I got from them

It looks like it should also go to the battery,  along woth the red, to sense the battery voltage - to measure if it needs charging or not.  But that's only an educated guess.

Hi Mike and anyone else interested in this, I've found this online. Does this make sense to you? It seems to work on paper but this is way above my knowledge. Knew I should of sent more time on electronic systems.
