In Reply to: Alternator Conversion Wiring Diagram posted by Bob G. on January 27, 2000 at 05:26:41:
Hey Bob G - I adapted that schematic directly from a GM car shop manual (an '80 Chevy Citation I think...) The Delco alternator has internal diodes, plus logic in the regulator chip that prevents the engine from running on and prevents the battery from drawing current with the ignition switch off. What DOES happen when the ignition switch is turned off is the warning light flickers until the engine stops turning - same as in a GM car. But the lamp does not pass enough current to fire the plugs. And once the engine (and alternator) stop turning, the light goes out and no current gets drawn from the battery. I've used this circuit for 20+ years on all sorts of farm and industrial engines. Trust me on this - as long as you wire it as shown in the diagram, it works great! Bob M PS - Someplace I have a schematic for the internal wiring of the Delco alternator. It's complex - fills an 8-1/2 x 11 page. I think only an electrical eng'r could understand it. But if I can find the schematic I'll take a digital picture of it and e-mail it to you. (One of my kids at college has "borrowed" my scanner...)

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.
