Follow-up report on previous charging problem

[231LV]

One of the great reasons this forum works so well is follow-ups on previously reported problems. I reported a frustration I was having with my volts on start-up well over a year ago. To recap, I would start up and the volts would hover around 12.3 volts before it would climb to 13.7v. Many opinions were offered from a voltage regulator issue to an alternator. One respondent offered that this was normal and the charging system was designed this way to prevent a voltage spike on start-up. The problem turned out to be a slipping coupler on the alternator. I suspect it had been slipping this whole time and progressively got worse which was verified when my last flight saw voltage sit at 12.0 volts. I now know that after replacing the alternator and using a solid state voltage regulator (either works or it doesn't), the most likely culprit is a slipping coupler. Hope this helps save some time troubleshooting a similar issue.
