early vs late model regulater/rectifier combo?

[sure]

I was wondering fi there was a difference between the points reg/rectifer combo and the later model ones?
mine took a nuts but I have an early combo reg/rectifer but don't want to hook it up if it will cause more problems.
will this work?
thanks

What I understand is the early model regulator regulates positive power to the stator brushes (and one of the brushes grounds to the alternator case)
and the late model regulator regulates the negative side of the stator brushes (and none of the brushes are grounded)

Other posts and sites describe changing early model brush holders when using late model regs....(some machining is requlred to the case). That way the later model can work.

I started a thread last week on a similar slant to this, you'll see I'm trying to get help on connecting wire colors in early and late systems...Haven't had much luck finding someone whose done it however...(I'm using aftermarket MikesXS parts

Would you be willing to describe the wire colors on your stock early and late model regulators for me and I'll keep trying to get help on the connect up?

I will draw up a schematic like the one below if I get the info..

I have recently exhanged the old style voltage regulator for a solid state one. The only reason for doing this was to free up some space on the battery box so I could mount the Boyer ignition box there. I just asked for a replacement to suit the early model.

If the only difference is the way the brush gear is earthed, I'd have thought it would be easy enough to modify a late type generator to use an early type rer/rect.

I fact I've looked at this and the only real difference is the plugs. The early models have two as the regulator is seperate from the rectifier. The late models have one plug. In both you have to one brush earthed, either you do this via the regulator (if you note on both systems the regulator is earthed) or directly at the brush gear. Its not going to affect the regulator which way you do it.

UK colours are - brush gear - Black and green (black is earthed on both)
3 whites - ac output
Brown - battery (switched via main switch)
Red- positive to fuse box
Sky blue is the neutral light, and feeds through the generator plug and is nothing to do with the charging system.
Yellow is the safety relay sense line and provides 7.4 volts when the generator is running as a means to control the operation of the starter solenoid when the engine is running.

That diagram above is wrong, ignore it. This is my simplified version of the xs charging using a solid state reg/rec unit. I have not shown the safety relay feed or neutral for clarity. Both feed through the geny plug, but have nothing to do with the charging system.
