I have replaced the battery, all wiring, voltage regulator, alternator, points/condensor, main battery cables.....truck has been running fine, and now I have a dead battery. All swithces are turned off, truck runs fine when jumped...will re start fine. Come back out in morning and the battery is dead. Could the ignition possibly be going bad? Im stumped as everything has been replaced, and I have had the battery and alternator rechecked. They operate fine.
