Hi! Guys
I was in the automotive repair business for nearly 40 years I saw some "overcharging" conditions, but none over 18volts. I like protection but some of the solutions mentioned are over the top.

Here here!  And to Jim as well.  I've never heard of anyone having any automotive electronics fried by an alternator failure.  If the regulator fails, it can damage the battery eventually, but you should be monitoring the voltage, and prepared to take action if it gets out of limits.  My plan is to let the EM-2 tell me it's too high, then turn it off.  If it went high, I imagine you could fly a long time even if you didn't have the ability to turn it off, so a stock alt is probably just fine.  
 
Cheers,
Rusty (domesticated today)
