HELP! Stranded!

Dirty cables to the battery and carroted or a bad corrosion at the battery wire to the post clamps.
If the key was left on and did not get turned off and you have points it will drain your battery if the points was closed.
If not, sounds like an alternator or :idea1: could the voltage regulator on the fire wall went bad :scratch: I think that will keep it from charging :-k:-k
Another tech will jump in here soon to let us know
