Dick - There's (2) relays inside early 6 volt regulators. One is the "cutout" and the other is the "voltage regulator". The cutout has a set of normally open contacts - i.e. the contacts are held in the open position by the spring. The cutout relay coil senses generator output voltage. When generator output exceeds about 7.0 volts the relay closes and completes the circuit between the generator and the battery, and the battery begins to charge. But if the generator voltage drops to about 6.o volts or so, the relay opens back up, preventing current from flowing from the battery back thru the generator and draining the battery. Thus as you suspected, if cutout points fail to open when the motor shuts down, the battery will run down thru the generator. The voltage regulator relay works similarly, only it OPENS on rising voltage (about 7.5 volts), and it's contacts control the generator field current which controls the generator voltage output. Hope this helps...

Fabricating Sidesheets - by Chris Pratt. The easiest and best first-time project for wanna-be sheet-metal workers like myself is flat or nearly flat metal cut and drilled to be a tractor's sidesheet. A sidesheet is sheetmetal to cover either the engine as in the case of early Oliver's, Massey-Harris' and many crawlers or the wiring and electrical components as in the case of the Massey-Harris Pony, Allis Chalmers' D Series (D-14, D-15, D-12, D-10, D-17, and D-19). The need for fabricating becomes obvious when you go to buy any of these
