Here's the link http://www.800-airwolf.com/pdffiles/ARTICLES/part33.pdf Go to page 3, at the top of the page where it discusses "Full Wave Bridge Rectifier". I've used this method with my 503 Rotax with a Hobbs for several years and it is foolproof, reliable, and accurate. Around $2 from Radio Shack. As I recall, the part number 276-1171 has been superseded but the new part number is standard stock.

In the end I just decided to attach the Hobbs positive lead to the ALT switch. I only activate it when the motor is running and always shut it off before turning the Master switch off. Works fine for me and eliminated oil pressure and other complicated parts.

For example on Rotax 912 engines, using this technique (see http://ch701.com/Builders%20Resources/electrical/912engine/jon_wiring.htm) even if you accidently leave the alternator switch on, the red alternator lamp will light up when the engine is shutdown. No special parts needed!

Verify that your inner and outer diameters match these parts. I have the Matco wheel that takes a 5"x5" tire. Matco told me that they use tapered bearings with a 3/4 inch axle, and the same wheel for some applications. So the wheel was set up for tapered bearings. The wheel needs a ridge on the inner side of the bearing cup to hold the cup in place. The front axle already had spacers that hold the cones in place. I did have to use shorter spacers. I cut a variety of sizes at home so that I didn't have to struggle on the tarmac. I like the design of the tapered bearings. Even if they fail the wheel can remain aligned with the axle. (I've seen failed tapered bearings, on heavy equipment, in the field, that we found during preventive maintenance. Didn't know until we looked.) When my ball bearings failed, as I was turning for a runup, the front wheel flopped over. If that had happened during a landing I may have cartwheeled. I feel lucky.
