Got my tags and went for my first drive! and broke down

[ufbugman]

Got my tag for my 71,c10 and went for a ride, 1st stop 2 new lower ball joints pressed in, 2 stop wash at the car wash, 3rd new wiper blades, and then 4th stop got some gas, And then she would not start. dead battery, got jumped and drive home.

I pulled the alternator off had it checked and they say it fine, battery is good also. I hooked up a volt meter to alternator and with the truck idling I had 14 volts. when I deconnect the neg cable from the battery truck stalls.

any ideas?

2nd problem is shift linkage can't get it in park...

specs on truck... 71 c-10 327 with th400 till cpp column
