Stuff like this is making me want to go experimental...
Over a month ago I had to make an unexpected landing as I was getting low voltage warnings and night was coming soon. Earlier on that same day I wasn't getting a mag drop on my left mag. This has happened quite often previously and we thought tightening up the screws behind the ignition switch was fixing it.
I asked the local mechanic if he could have a look and possibly tighten up those screws. He mentioned all the screws were tight then had an idea. Popped open the oil door and reached way back behind the mags and kinda shook the wires back there a little bit. He gave me the reasoning behind it but I couldn't remember. Something about the frayed wire shielding. Regardless I was now getting a good mag drop.
I probably should have noticed this earlier but into the flight I noticed I was no longer charging and was getting low voltage warnings. I landed at the nearest large-ish airport I saw in hopes of getting decent access to a maintenance shop (I'm still kicking myself in the behind for this.) I explained what happened to the shop and they said they'd check it out when they had time. At the time I was trying to avoid thinking about the logistics of getting all my crap back home commercially or via rental car. When they were troubleshooting it I finally noticed the alternator breaker was popped. I pushed it back in and we all thought I'd be on my way. Well the breaker kept popping and they didn't have time to investigate further so I got a rental and drove home.
They assumed it was the alternator, got a new one ordered, put it on, and now it turns out our original alternator is in fact probably fine and they still have no clue what the issue may be.
I feel like they're ignoring the obvious where the previous mechanic that touched it fumbled with some wires and potentially fixed one issue and caused another. I'm about at my wits end with this. They have had the aircraft over a month and made zero progress from what it sounds like.
Would any of you guys have a clue what may have happened so I can guide them in the right direction? I don't know how much they'll listen to me since they seem to have ignored everything I told them at the very beginning.
