Yes I charged it fully which is why I am still somewhat worried that changing the alt didnt fix the problem.
It was only maybe 2 miles to the parts store. I'll write back if it dies again. Thanks

I really think you should invest in a cheap voltage meter and just periodically check your battery voltage just so you know what's actually going on in there.. I would still be weary at this point if it was fully charged and it died even with the new alternator in it.

Or better yet spend the extra $4 and get a digital one:

I bought one today and it showed the battery at around 12 volts. I'll keep checking it.

 

It should be above 12.5 after about 30 min running and between 13.9 and 14.8 running.

 

I'll be keeping an eye on it. I sure don't want to get stranded again.

 

This is a rough chart of voltage vs charge level:

12.66V - 100%
12.35V - 75%
12.10V - 50%
11.95V - 25%
11.70V - 0%

You may get all the way up to 13v after a full charge, for a short period and then it will drop down to 12.66 or so.
