wiring for 12-volt conversion 1940 Farmall B

Posted by Jimmy on February 16, 2004 at 11:14:14 from (209.247.222.48):

I have just finished putting my 1940 Farmall B back together. I used Robert Melville's wiring diagram #11, "Generic Delco 'single wire' Alternator Conversion" to wire the tractor. I bought a rebuilt alternator. The sticker says NAPA Power remanufactured alternator 213-4013 12V 63A rated. Stamped on the alternator - 110 062 8129 12V NEG. On the back of the alternator there is one stud marked battery, one stud marked GND, two small plugs - the left marked 'R' and the right marked 'F'. When I turned the push-pull switch on the amp gage showed a slight charge. After cranking it still showed a slight charge. I thought it should show a slight discharge when the switch is turned on and then a plus charge after cranking. I changed the wires on the amp gage then when I turned the switch on it showed a slight discharge, but when I cranked it, it still showed a slight discharge. I changed the amp gage wires back to where it shows a slight charge when switch is turned on and after cranking.

Question is: is it wired up right?
