You must be sure your alternators working. Check AC input it's the three yellow wires. Check volts between 2 wires an shoul be 35 + volts. Check between all three.

If the battery is charged, its charged..... redpoint5 is right, check the battery when hot... If the battery was not charging i would then look into the charging system, rectifier, etc.... Is it an air cooled engine? Sometimes engines can get a little warped when hot... My grandfather had Corvair vans as taxis that somehow always got overheated, after that they would never start hot. So, he had to leave them running all day.... If your battery is OK you may want to have a look at your starter.... Or, bypass the selenoid with a jumper cable and see if the starter kicks over fine when jumped directly...... That would indicate a bad or worn selenoid.

Replace your battery when its being tested there not testing it under a heavy enough load. A battery could have a dead cell in it and still show good on the charger. I've had that problem a few times.

Sounds like you need to monitor what's going on at the battery. Hook up a volt meter to see if it's charging. Check and clean all connections / plugs. Check connections at key switch. Look over all wiring for shorts or broken wire. Disconnect everything but motor wiring to narrow down the problem. Starter drains battery faster than it can recharge.........
A dead battery will mess up a charging system and a bad charging system will kill a battery.

hav the charging system inspected-it may be a failin alternator too--make sure batt cables are tite--buy a clymer manual and learn maintenance
