I have a 1978 C182 Q. I recently experienced my alternator turning off and the
high voltage light coming on. I cycled the switch (1/2 master) and got it to
reset every time, however, the interval between episodes varied. I had the
Voltage Regulator and the Alternator replaced (new) and flew a couple of
flights since with no problem... until my last flight. Last flight it happened
again. The Alternator switched off and the high voltage light came on. I
cycled the switch and it reset.

What else is causing this? Is it a bad switch? Loose connection at the bus?

I had loose ground connections under the panel and on the breaker buss...

Has anyone else experienced this and what was your solution?

Tighened the above and replaced the battery - it was weak and wouldn't
turn over the engine if it didn't crank almost immediately...

Any feedback is appreciated.

I'm good at that...
