With the battery disconnected, pull the top off of the VR. There will be two coil/relay looking units in there. Reconnect the battery (the cap can violently short out the system as it is removed!!) One will be the cutout relay. It will have a heavy winding around it (probably) and heavy contacts. The other will have smaller contacts. With it running at 1/2 throttle or more, use a small twig, or plastic knife/spoon/fork handle, to push the small set of contacts together more (apply pressure lightly in the close contact direction) The generator should begin to increase out put. If it does, then use a volt meter to assess the battery voltage (across the battery termonals) and adjust the spring, tab, or screw to cause more pressure on the contacts. as you do this watch to be sure you do not short anything to ground (smoke). The voltage should be set to 7.2 to 7.3 volts. Shut it off, disconnect the battery, and put the cover back on the VR. Restart, and check the voltage. The voltage may have changed due to the cover's effect on the magnetism in the vr. IF TOO LOW OR TOO HIGH, ADJUST AS ABOVE TILL GOOD. This can take two or three removals of the cover. If it has no effect when pushing on the contacts, a new (possibly NAPA) VR is needed. JimN

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
