Gas IH-B414 voltage regulator

Just cannot find it!! Does anyone know how to get at it? I"m trying to polarize it and generator to Neg ground as well as clean it up. I have a newly rebuilt generator that generates lots of amps on the bench but doesn"t seem to be charging the battery when installed. Any ideas??
Thanks

I dont know how to get at it BUTTTTTTTT Its the Generator NOT the Voltage Regulator that gets Polarized BEFORE you start the tractor, otherwise (if gennys is at opposite polarity) you might damage that new Voltage Regulator...... Polarize the genny n then try it MAKE SURE that BOTH the genny and the VR have good grounds!!!!!

TO POLARIZE A GENNY IF YOU CANT GET TO THE VOLTAGE REGULATOR

Use a lil jumper wire to momentarily flash jump/spark any hot ungrounded battery voltage feed source (like from hot ungrounded battery post or where the big battery cable attaches to a starter switch or solenoid etc) to the gennys ARM post and you should get a spark... NOW ITS POALRIZED

I will post a link to my Non Charging Troubleshooting Procedure, but heres a short clip from it which may provide insight unti you do all the tests in my procedure. POLARIZE THE GENNY FIRST BEFORE STARTING IT REMEMEBR.... Also if you reverse a tractors polarity that uses an ammeter its leads need swapped so it dont register backwards...Also put a voltmeter on the batery and setting it ought to read around 12.6 volts but then once rinning at fast RPM it should rise to the 13 to 14 and over range IFFFFFFF shes charging...

a) VOLTAGE REGULATOR SYSTEM: With the tractor running, temporarily ground the Gens Field post to case. If she charges then but NOT otherwise, the VR may be bad, or a wires missing from VR's Field post to the Field terminal on the VR, or the VR isn’t well grounded.

b) IF IT’S A CUTOUT RELAY SYSTEM and she charges only if you dead ground the Field but NOT otherwise, its either a bad switch or the switch isn’t well grounded or else the wires bad or open from the Gens Field post up to the switch. INSURE THAT GOOD SWITCH GROUND AND WIRING

If she still don’t charge, leave the Field grounded and jump a wire across from the VR or Cutout Relays BAT terminal over to its GEN terminal (jump by passes the cutout relay) and see if she charges. If then but not otherwise, a VR's cutout relay isn’t working correct (maybe points burned/carboned) or a Cutout Relays NOT working or not wired correct.

7. With the 2 steps above, you have basically by passed the VR or Cutout relays functions, so if she still don’t charge, you're left with a bad battery or wiring or the Gen itself.

If polarizing and a good ground on the Genny and VR dont help, go here and these simple tests can help diagnose the problem......

I don't understand what you are trying to do. If keeping your tractor original, it's supposed to be positive ground - not negative. You can buy a new regulator on this website for $42. If you want to change things and not stay original, why bother with a generator that has very low charge capacity? It puts out 11 amps max at 1700 RPM which isn't much. Yes, you can find "convertible" regulators to run it, but doing so will cost more than installing a 12 volt alternator with a built in regulator - and the alternator will work much better. B-275s and B-414s came originally with positive ground Lucas regulators #s RB108, NCB1008 22703, 22785, 22756,RB37365, RB398, RB405, RB408, RB418, RB448, LRC107, NCB118, NCB120, Perkins: 2872508.
