If the alternators are getting hot, Suspect.....

1. Battery has a dead cell, Charge the battery with a charger, Remove the charger & monitor the voltage with a meter, A fully charged battery will have at least 12.6 volts, (a surface charge of 12.6-13 volts will linger for a while on a good battery) If it drops below 12 volts.....The battery is bad & is overworking the hell out the alternator.

2. Bad Connections, Disassemble both battery cable terminals & clean them, Remove the Nut, Then the Rubber end will slide off the Cable, Clean the Nuts & Cable ends & reassemble. A Radiator Hose Pick is the perfect tool for this.
