I checked the output of my alternator with a REAL meter and it is putting out around 18.25 volts?
Damn! That seems high!
Is it possible to be too high?
Isn't 15.5 V about right?

Best to measure at bat terminals. Engine off should read 12.5 volts, engine on 13.5-14.5 volts. Under 13 or over 15 on the latter readings indicate alt problem.

Hmm, this is eerie, I was just thinking of my car, and it's voltage. I had another sparkplug crack, and how could it crack ? The parts guy said I broke them or there was something wrong with the car. The service manager said no way the car could break insulators on a sparkplug so it was the parts guy or me who had dropped them. I spent another $130 having the car go to the dianostic machine at the Ford dealer to be told there was absolutely nothing wrong with it. But something is cracking those insulators, could it be too much voltage ? You have had broken plugs too. I very, very carefully put new plugs in 5 days ago. 2 days later the car is missing again, and I have a broken plug. There's no freekin way I broke the plug while installing it. Or why would the first set of Motorcrafts last 1 whole month, THEN break. No, no, no, no, something is breaking them, and I'm thinking it's too much voltage, not insufficient voltage like I originally suspected. Before I pick the car up I'm going to have Ford check the voltage, because I bet like yours, mine is too high.

I'll say this...
When I pull the plug wire while the engine is idling the SOUND of the spark before I pull the pull too far for the spark to "make" is LOUD!
It isn't a puny spark voltage!
I am going to check all of this out further.
I'll update you when I get results.
