The typical winter by pass wont cure a totally shot VR, it only slightly increases the rate of charge....... (but your VR may just not be well grounded!!!!)
On many 4 terminal VR's, BAT LOAD FLD are together while GEN/ARM is by itself or underneath, sure youre wired right????????
If theres no spark when polarizing, youre not passing current through the gennys Field windings, either cuz the VR dont have a good ground (try a jumper wire from the VR to a good clean ground n see what happens),,,,,,,Or the wires open from FLD on VR to the FLD terminal on the VR,,,,,,,, Or theres an open in the circuit somewhere....Or the Field windings (input) inside arent electrically connected to the gennys ARM post or if its a 3 brush genny the third brush may not be contacting the commutator........
Try a good hot voltage source jump (like should be present on the VR's BAT terminal) direct to the Gennys ARM post n see if she sparks n polarizes???????? If so there but NOT via ARM on the VR, the VR is bad or not well grounded
To Polarize use a jumper and momentarily flash jump from BAT on VR to GEN/ARM or direct down to the gennys ARM post
NOTE this if for an A charging system NOT a B!!!! An A VR and A wired genny dont mix with a B system !!!!!!!!!

Today's Featured Article - Tractor Hydraulics - The Basics - by Curtis Von Fange. Hydraulics was one of the greatest inventions for helping man compound the work he can do. It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
