Just how much does it cost to replace the diode in question? It is probably pretty cheap to just replace it if you feel it is suspect. My father has a tractor that was having intermittent start but not run problem. If the problem didn't exist at the time, then we couldn't figure out the problem. Sometimes, the tractor just drop dead in the middle of the field. Never been able to figure out the problem and then the tractor would just start right up and run! Crazy! My father had done quite a bit of research online and was narrowing down to 4 different diodes in various places on the green tractor. Trouble was, which one of the diodes was intermittently failing? And where were they on the tractor? (These diodes were hard to find, pig-tailed to the wiring harness buried under something). Until one day the tractor just would not run (not an intermittent problem now, just constant)..... then we able to find the diodes and test them until we found one open both ways. Replaced that diode and tractor runs. For next time, we now know where are all them damn diodes! Spares on hand @ 9 bucks a piece.

Diodes inline in a dc circuit as used to block AC from the charging circuit since the stator/voltage regulator don't have a large capacitor incorporated to filter the AC out.
