Since this PCM had the same symptoms as the original that blew, I'm assuming I can fix it for a spare. An aircraft’s ignition system is the result of careful design and thorough testing. To measure the output voltage, we place the same multimeter set in the DC voltage setting and now place the positive probe of the multimeter on the output pin of the regulator and the negative probe on the ground pin of the regulator. A 30 minute test flight in the pattern reveals no more symptoms like before. Haynes in its cooling section says there should be a sideways deflection in the middle of the longest run of 1/2" on 'early' models, and 1/4" under an applied load of 7. A shorted or old battery can cause premature failure of the charging system so it's a good idea to replace the battery at the same time as the alternator if it is three years or older. Principles of selecting mounted bearing solutions. Well, if you're really paranoid, make your own bridge rectifier but use 8 diodes instead of 4, with 4 series pairs.
