polarity

1) to change from pos to neg ground is there anything else to change besides the coil?
2) how do you polarize the generator. I find conflicting information on google. Thankyou
 
Indeed change coil polarity (and battery DUH), you nailed it.......PLUS Change
ammeter polarity if so equipped.

To Polarize the generator BEFORE !!! starting, I use a jumper wire or other
conductor to momentarily flash/jump FROM BAT on the Voltage Regulator or Cutout Relay
over TO the VR's GEN/ARM terminal (or Gennys ARM terminal see below) and you should
get a small spark...

On some VR's where perhaps the BAT or GEN/ARM terminals may be hard to get to, I
Polarize by momentarily flash jumping FROM the hot ungrounded battery post (OR BAT on
a VR) direct TO the generators ARM terminal......

Its BEST if the VR is matched/suited for your POS or NEG Ground system

Im talking about Generators here not Alternators WELL DUH

Those are the two methods I used to Polarize a generator, there could be others...I
have at times on Class A systems had the Generators FLD terminal grounded when
polarizing, but it seems to still polarize okay if not..

(quoted from post at 16:46:27 08/15/23) PS I forgot to mention this is my method for Class A Charging Systems

ame procedure is also fine for Class/Type B.. I don't ground the field in either A or B, but it will be damaging in B.

Polarizing is simply momentarily running current thru the Field Coils of the generator to magnetize the pole pieces, so that correct polarity exist at start up. John knows, but I added this for others.
 
Case used a B type system at one time and we were instructed to remove the field terminal wire from the generator before polarizing so as to not shoot heavy current back through the Regulator VR reed to ground. that worked well for us.
