Regulator/Rectifier

[Spanner1972]

So if I get the modern version (above) and wire it up I'm good to go? Surely it can't be that easy. Well easier than I though. [ Guests cannot view attachments ] I'm gonna be cheeky and ask can someone alter this pic and put in the new regulator/rectifier. Thanks.

Ok Spanner,

Assuming you have the DSS type Regulator / Rectifuer unit.

Starting with the old REGULATOR at the top of your picture & working vertically down...

Disconnect the BLACK wire, and connect it to one of the BLACK/ RED spades of your new unit.
Disconnect the WHITE wire, and connect it to the other BLACK/RED spade of your new unit
Disconnect the GREEN wire, insulate it, and tape it up out of harms way.

Now your old RECTIFIER...
Disconnect it from the bike via the large loom plug, ie 3x YELLOW, RED/WHITE & GREEN
Plug the bike loom connector into your new Reg/Rec unit.

Job's done.

(if for some reason you don't have the loom plug simply connect the YELLOWS together (any order), the GREENS together and the bike RED/WHITE to the new unit RED. Ensure all these connections are soundly insulated & stowed securely.

Simon.

Thanks for that. I appreciate you taking the time out to explain. Nice one.

Is a cb550 rectifier/regulator the same as a cb500 one? Done a bit of research on the web and it says it is. Just need clarification. Thanks.

Yes, it is, and the same as the sohc 750s

Thanks. Found a new one on Fleabay for a good price.

Gents, is this ok to use? Thanks.

Hi again Spanner,

The eBay listing is only for a rectifier I think... ie the bit that RECTIFIES the 'wiggly' alternating voltage into something more palatable for the battery... which likes DC.

You then need something else to REGULATE that voltage value... so you don't boil your battery... ie you'd further need a Regulator.

Which is actually how these old Honda's did it... ie 2 separate units.

I thought you were after a Regulater / Recifier all-in-one unit... if so this isn't for you. At the bottom of the same eBay page is a combined unit however, and labelled as such. It'll likely have a couple of extra wires to it... a black & a white.

But in answer to your question "is this OK to use" I'd have to say yes.... but with a Regulator.

Hope this helps,
Simon

Thank you. Now I know where I stand and what I want. A plug and 2 extra wires then. Thank god I didn't buy that one. Thanks for pointing me in the right direction.
