Identifying field terminal on generator

Actually, you need to connect the field terminal to ground, this will force the genny to full output voltage so you don't want to run it that way very long.

No wire should go to the starter, they should all go to the regulator, one wire is the "armature" or "A" which is the genny output/regulator input , the field wire, as you stated, controls the genny's output & there's a ground wire to make sure the regulator "sees" the same ground potential as the genny does, without this the charging voltage may do funny things. There's a forth wire on the regulator, that goes to the battery although for sake of simplified wiring it may go to the battery terminal of the starter solenoid.

If you clean the crud off the genny you'll find the terminals are marked for what's what.




I *think* the green in the above pic is the field, that matches with the wiring diagram in the tech section.

Hopefully the genny ground & in-general ground are functionally equivalent

Anywhere should work.

The reason they tie the genny & VR grounds together is that smetimes the regulator, which are held to the firewall with sheet metal screws, vibrate loose giving them an iffy ground connection through their base, that blue wire eliminates that problem.
