Need Help Again...Im going out of my mind!! PLEASE HELP ME! 200 1986

the problems are coming from one of these 3 things:
or battery
or voltage regulator
or alternator

or together (less probability)

The number of electrical consumers you put on together is not to the point!
whatever a mechanic may say (mechanic <> electrician -)° )

Point is that the battery has to keep it charge and that it is proper charged though the alternator, which seems OK, (because of the 14,8 voltage reading of the voltage regulator)

so only thing that remains is your battery: very bad state probably or premature wear, too less acid/water inside

================================
I suppose you have the bosch alternator = 55 amps
and your battery is around 60 Ah;

soo with the alternator running at full charging power it will take at least 1 hour of complete charging from no charge at all

but wehn car is running there some other electrical consumers which will drawn some of the charging current

================================

At 10 A charge; it will take 60/10 = 6 hours to charge your empty battery
================================


================================
My advice: try to borrow a battery of donor car and compare the behaviour...
