3 Post Voltage Reg w/bottom terminal/Mod 725

Recommended Posts

Maybe the information I need is here somewhere, but ....

I have a Model 725 that I'm converting to electric start.  I have the starter/generator mounted, pully on flywheel and belt hooked up, but I'm stumped on the voltage regulator. 

I have a new one (voltage reg) with three tabs on one side and a post on the bottom.  The pages from the parts manuals show the same regulator, but the images are confusing.  It looks like some wires are missing from the diagram.  I know the battery post goes to the battery.  The Generator post goes to the A or G terminal on the SG, and the Field post goes tot he F on the SG.  The parts illustration shows a wire with a note saying to connect to the bottom post.  I'm guessing the other end goes to the A or G terminal, but since I can't tell for sure which wire goes where from the illustration, does anyone know for sure if my assumption is correct?  If not, how does the bottom post wire up?

Thanks in advance for any help -

I think maybe I have it figured out.  The regulator has L, B, & F on the tabs.  The only connection remaining is for the Armature post on the starter/generator.  I'm going with that.  Thanks  - Dick

The regulator should have (4) terminals, L-lights, B-battery, F-field & G-generature.

A brand new/unused regulator must be polarized. Instructions state: After new regulator has been installed and "grounded battery cable" connected to battery, BEFORE STARTING ENGINE POLARIZE GENERATOR TO MATCH BATTERY. MOMENTARY TOUCH ONE END OA A PIECE OF WIRE TO REGULATOR TERMINAL MARKED "ARM" OR "GEN" AND THE OTHER END TO TERMINAL MARKED "BATT" THEN REMOVE. A SPARK WILL OCCUR WHEN WIRE IS REMOVED. THIS IS NATURAL. DO NOT TOUCH "FLD" TERMINAL! REGULATOR IS RUINED INSTANTLY IF IT HAPPENS.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
