I have been reading archives for days and trying to figure out the charging system problem. My BN has a magneto and lights with a 6 volt pos ground. Am using the 4 post VR. When it runs shows slight discharge. Turn on lights and discharges to almost 15. Lights don't change with throttle change for dim or brightness. Voltage across battery shows 6 with tractor running 3/4 throttle. This is what I did:
1. Belt is nice and snug
2. Grounds cleaned with sandpaper. Jumper wire to ground made no difference. Ohm meter between VR and Gen and frame reads 0.
3. Wiring is all new and according to John's instructions. I am confident that it is correct.
4. Gen 3rd brush is already set 3 bars from the other one.
5. Ground F terminal on gen while running and no charge.
6. With F term grounded ran jumper from A to Bat and it DID CHARGE to almost 15 on the meter.
7. Remove VR cap and tried to adjust spring to hold set of points closed (made spring tighter) with no change.
8. Layed screwdriver across the coil and points and it DID Charge again.
9. Bought a new VR from tractor supply. Connect battery and polarized it and still no charge I even read about the guys who said there system didn't charge until running it for awhile then worked. Let it run for awhile with no change. One note: the VR I bought had been opened and I think returned. Could it be bad? Or am I missing something? I am super frustrated. Please help. Thanks

Measuring with Calipers - by Staff. The legs of inside calipers are curved outward at the extremities to facilitate measuring small holes, while outside caliper legs have a large curve inward to increase their capacity for large work. Firm-joint calipers are adjusted approximately by the hands and then set to the feel of the work by tapping them on a metal surface. It is a common practice when opening calipers by this means to tap the top of the joint. It is better, if possible, to tap the inside of the legs, as repeated blo
