Question type: Maintenance & Repair

Fully charged battery, truck will start daily. Drive it for 15 min or more and wont start. Slow cranks like the battery is dead. did the alternator test by pulling both cables off while running and it still ran. jumped solenoid with screwdriver...started up fine. But if you drive it for a period of 15 or more min it wont start. draining the battery.

I would charge the battery again and have a load test done on it. It may be on the way out. Not dead but not strong enough either.

I have tried 3 different batteries. one was new.

could it possibly be the voltage regulator?
