Regulator question on '68 model 124

[green 4 acres]

speaking of the regulator has any one found a solid state regulator to use I mean this is 2011 automotive changed over in early 80's mine is junk and not charging I need to go to the salvage yard to see what I can find volvo had one in thier replaceable brush pack

Someone else knows more I am certain but of what I do know; IF you manage to change to a regulator and add a starter instead of a charger / starter you can use a solid state voltage regulator.
I was trying to use the one I have before I went to one of our sponsors to get another. From what I found the good VRs will run 70 to 90, I am sure there are cheap substitutes at car parts places but my experience has proved that to save on cheap parts always costs more in the long run.

ONE ROOK IM NOT SURE WHAT YOU ARE SAYING ops cap lock was on --the starter circuit has nothing to do with the charging circuit except for feedback which ss reg are built for . a ss reg does the same thing a mechanical reg would . the 1 possible problem I see is a different number of poles giving a uneven hook up to the reg as for $ I have a few alternators here to scavange from or a pick ur part yard for a few $ - I intend to try it soon (soon beeing a year or so)

I do understand that the ss reg cannot be in line between the windings and + post (as in a altern. set up) and still have a starter function

The regulator "feeds" current to the generator to make the generator generate IIRC. No one does that today, they just limit the output.

You need to separate the generator/starter functions to resolve this.

I'm sure we could get some heads to come up with a solid state solution, but, the market would be limited.

You remembered incorrectly...the voltage regulator limits the output of the starter/generator, just like with more modern electrical systems. If you bypass the regulator by grounding the "F" terminal, maximum battery-boiling, generator-overheating output is the result if the starter/generator is functional.

These darned ancient mechanical ones only last 40 years... what's the world coming to?!

I did a valve job, rings are center of spec, bearings tight and surfaced the head. Runs like new and starts right up, but MOST important is the voltage regulator and wiring change works perfectly. Thanks all for the input

BTW, the horn is in the spare parts bin

Glad you got it running like a top!
