Alan..... ...as a general rule the 6 volt 5-nipple sidemount roundcan ignition coil is fairly bulletproof. And yes, yer replacement coil (+) should be connected to distributor terminal, iff'n yer still 6 volt POSITIVE GROUND. Rule is (+) to (+). Usually, most ignition system failures occure in the first hour of operation. Common failures include "bad coil"; broken points; slipped points gap; shorted/leaky condenser; sparkie wires slippin' back outta nipples and loosing contact; cracked 5-nipple cap; broken rotor; Your report of 6 volts outta BOTH sides of yer coil, tells me yer coil primary is continious (good) and yer points are open. And iff'n ya was to stick yer voltmeter probe down the coil center nipple, you should read 6 volts down there too. (points open) and I'd consider the coil secondary good too. I'm assuming that yer tractor ain't runnin' at this time, so I'd pull the cap and check that you have 6 volts to the moving side of your points. (points open) And obviously, points gap 0.025" while yer inthere. The #8x3/16" points screw threads wear out (visually look good) but won't keep the points gap tight. Check that. New screw p/n 355047-S7 is also used in many Ford automobile distributors..... ....Dell, the self-appointed sparkie-meister
