Voltage Regulator Wiring HELP!!!

I am about to put a newengine in my Cockshutt 30 and I received a newer 12v generator, old look, which included a 4 terminal, voltage regulator. L, Batt, F and Gen. are the terminal ID"s. I laid out a new wiring diagram from what I could find on-line but I seem to have all the accessories connecting to the "L" terminal, like the lights, the ignition and starter switsh power. I thought those would have come off the battery terminal side of the selenoid. I have a sketch that I could send but this site won"t let me post a drawing or a picture yet. Please HELP!!

hat is the way the "L" terminals work.
 
Easy answer:

With a 3 terminal (BAT GEN FLD) VR the loads (lights, ignition etc) are often fed voltage from the LOAD (NOT to battery/starter) side of the ammeter. In theory, but subject to wire and resistance etc., the VR's BAT terminal is electrically the same as the load side of the ammeter, cuz the load side of the ammeter is wired down to the BAT terminal on the VR.

With a 4 terminal (BAT LOAD GEN FLD) VR the loads (lights, ignition etc) are fed instead off the LOAD terminal on the VR.

NOTE on many tractors, the SUPPLY side of the ammeter gets it voltage via a wire down to the starter switch or solenoid where the big main input battery cable is attached and the other LOAD side of the ammeter is what wires down to BAT on the VR

You mentioned something about L to the starter switch power !!!!!!!!!!!!! Ifffffff you mean where the big battery cable attaches to a starter switch or solenoid THATS NOT CORRECT. Normally with an ammeter the SUPPLY side of the ammeter has a wire to the ungrounded battery post or the big battery cable where it wires to a starter switch or solenoid (other Load side of ammeter to BAT on VR). The L terminal does NOT wire there, it just supplies voltage to lights and ignition etc

Got it???

GOT IT! Great reply. As for the starter switch solenoid, what I really meant was the small terminal on the solenoid connected through an intermittent starter switch connected to the L terminal for starting the motor. Is that still correct?

Any possibility that you could review my wiring sketch to confirm that its correct?

Thanks Much! Just have to type in the H Tee Tee P and colon and // in front of the above link to see it. If that works. I can't post pictures yet for some reason.
 
I don't have any heartburn with that, loads are supposed to be fed from the L terminal and that's a load it sounds like

I cant get that link to work

nor

Neither will work, Oh Well we tried

our schematic looks fine to me. However, I will mention that since you are pulling together a generator and a VR that are apparently not original to the tractor, keep in mind that there are Type "A" and Type "B" gens & VRs and the gen & VR must be of the same type. Can't mix & match, here.
 

Great! I received them both from Irv, who is quite an experienced cockshutt guy. I hope he knows this. I assume he does as he had the parts in stock and said many others have used these to make the switch. Is there any way to differentiate between the a 7 b types?

es, but getting both from same experienced fellow, you ought to be OK.
 
Yo JMOR, far as I know, Fords other then 8N were Class B and I believe Massey Harris were Class B but most all others Oliver IHC ??were Class A

You have any info on that???

o comprehensive list. It is very curious though that the very first 12,584 9N tractors used a class/type "B" gen & VR, then just 3 brush with cut out until the 8N, which as you said, went to class/type "A". Kinda like their Model T using NEG ground, then going to POS gnd until 1956, then back to NEG gnd!! Just couldn't make up their minds!!!
My Delco-Remy equipped IH-101 combine (early '50's) is "A". I expect any of the old tractors using DELCO_REMY will be "A". Those 8Ns had Auto-Lite VR and back in those days Chrysler corp vehicles were "A" systems, so that is consistent.
It "MAY" be that just about the only "B" systems are those first Ford tractors, the 1939 Ford automobile, and the later Ford products from about 1953 on.
Would be neat to see a chart for gen/VR systems kind of like the battery ground chart showing POS/NEG for all makes & years.
