Gen. not charging

[Dave Schindel]

Hi guys, yes,I did polarize the gen. And it is a 3 brush design. My issue seems to be more with the F wire from the gen. and what it should have as far as voltage. This is on a carrier so the switch may be different than on other vehicles. With out the engine running, and with the switch on,the field wire on the gen. should be fed by power from the battery, through a light, and to the F wire,right? As it is now,with the switch on,there is no power going to the F wire.Thanks for all the ideas and discussion.
