To fully understand this post, I suggest reading Part 1 first!
'B' circuit generators, like what is on Ford products, differ from 'A' circuit generators by the way they are controlled. To test a 'B' circuit generator on the vehicle, remove the field 'F' wire from the generator and set it aside so it won't touch anything, then using a short jumper wire, jump across to the 'ARM' or 'GEN' terminal on the generator or better yet, use a longer wire and jump to the hot side of the battery, which could either be positive or negative depending on which side is grounded. This will kick the generator into full charge which can either be read by the gauge in the dash or using a meter across the battery. Be careful, because I've found that these generators are usually have a higher amp output than the 'A' circuit generators and will really cook!
To polarize a 'B' circuit system, After everything is hooked up and before starting the engine, Remove the field wire from the REGULATOR'S 'F' terminal and touch that wire to the 'BAT' terminal on the regulator. Just hold it on, for only a second and when you remove it there should be a spark. Warning, do not touch the regulators 'F' field terminal to the 'BAT' battery terminal or you will fry the regulator! (As always follow the instructions you receive with the new regulator if they differ with what is written here!)
