So, I replaced the copper wires with the spiral-wound wires last week, and also replaced the condenser and points in the distributor. I re-timed the distributor to #1 TDC, or just slightly after (as per the owner's man), and got the old girl fired off. I had to play around with the carb mix, as she didn't want to rev up, but kept backfiring and burbling through the oil-bath air filter. What a mess that made! I got it going though, and she sounded better and started faster than ever she did when we first got her.
Today I rebuilt the alternator, needing only to replace the regulator. I replaced the diode trio and brushes at the same time, just as a matter of course. Since I had the DVM out for checking the old rectifier and diode trio, I checked the coil's primary resistance. Hold on to your hats: 0.8 ohms!
By comparison, an old can-style coil from one of the Jeeps measured 1.5 ohms on the primary, and the resistor mounted to its bracket also measured 1.5 ohms. Combining them gives 3 ohms, which, at 12v, will net only 4 amps, whereas I'm pulling MORE than 12 amps through the points! Yikes, no wonder the condenser and points were trashed!
So, back in goes the old coil and resistor, and the admonition is reinforced: if it ain't broke, don't fix it. I was just trying to use what was on hand, fie on me for being a cheapskate. I've got the new plug wires, that should help, and with the alternator charging again (presumably; I haven't run the rebuilt unit yet), I'm off and mowing.

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th
