Title: Solid states
Post by: royhall on December 04, 2014, 05:27:46 PM

Hi. Just got a solid state Rectifier/Regulator for the old F2. Of course its arrived without any wiring diagram or instructions. Have posted a photo, can anybody tell me where the black and white wires connect to. They are both male spade fittings. Also, I assume it bolts on in place of the existing regulator. Thank you very much.

Hi Royhall, had much of the same problem with one I bought on E-bay. Do you have any idea of what bike it fits or a part number ?

Hi Roy,

1st up I've a K2.... and assume the F2 is essentially the same..... Pete?

The unit you have replaces 2 original bits, ie the regulator (gold box) & the rectifier (black jobby under the fuse holder in the bottom pic)

The unit's loom plug you have (3 yellows / green / red ) connects to the existing loom plug that went to the original rectifier. (white terminal block, top pic / RHS)

The flying leads (black / white) go to the existing loom connectors (same colours) that fed the regulator.  There will be a spare green left over (regulator earth) from the bike loom here... just tape it up & tuck it away.

The below (embarrassing) pic of my bike as I bought it showing those black & whites going to the bike loom, and my restored pic as a ref showing the original bits you're now replacing,

Along with Pete's wiring diagram hope this helps...

Simon

Thanks guys that's cleared it up. The wiring on the F2 looks like its the same but the layout is slightly different. See photo. Cheers all.
