Starting Problems
I have a '75 f250 with a 460. The only way I can get it to start is with a strong battery AND a booster pack. I have had the starter tested, changed the selinoid. and installed new cables. The only change was that now it will crank slowly with just it's own battery, but not fast enough to turn over. Last time I tried it boiled the battery!
Any Ideas?

It sounds like your battery is dead to me, but I can't be sure because I'm not there to hear it try to turn over on its own power.
If the truck is making a "whhhhommmmp...whhhhhommmmp....whhhhhommmp" sound when you try to start it on its own power, then it's most likely your battery.
I would also be aware of loose/frayed wires. Something may be interupting your truck trying to start.
Also, if you have had the truck start, but with the charger connected to the battery, try checking your alternator wires and alternator itself. A bad alternator may be killing the battery, forcing you to charge it or use the charger.

Measure the battery voltage with the truck shut off, then measure the battery voltage while a buddy cranks the engine over. Post back with both numbers.
You can't measure length without a ruler - in the same way, you can't solve electrical problems without a multimeter. If you don't have one, you'll need to get one.

What about digits, handbredths and Cubits?
J/k a DMM is one of the most powerfull tools a mechanic will ever have. And decent ones can be hand reasonably at Harbor Freight.
For a few more bucks the Craftsman multi-meters are worth a look. I have one over 20 years old and another that is 6 that gets beat on nearly every day.
