When you polarize a genny on the cutout relay system, youre basically by pass jumping around the relay and applying hot battery voltage to the gennys Armature terminal and Id expect a current discharge out of the battery. You just flash that momentarily to get a spark then youre done polarizing.
A working (i.e. NOT stuck closed) Cutout Relay should normally be an open connection between its BAT and GEN terminals and only latch closed once the gennys voltage exceeds the battery voltage. It requires a good frame ground (usually via the genny) to work properly. If the relays contacts have burned/welded/carboned closed they can easily stick again as once the bright shiny silvery coating is gone they dont last long. Sure yours is wired BAT side to the ammeter and GEN side to the gennys ARM post and it has a good ground??
If the genny is okay and polarized !!! and works on one tractor but NOT another, I suspect a light switch (LHBD) problem or the switch isnt well grounded or the wires bad from FLD on genny up to the switch.
In my procedure below (Para 5) it will tell alot to see if she charges when you dead ground the gennys field ??? If so but NOT otherwise, then again its a bad light switch or its not grounded etc.
