BATTERY DRAINING

1991 Ford Explorer

Electrical problem
1991 Ford Explorer 6 cyl Two Wheel Drive Automatic 221000 miles

I bought a 1991 ford explorer for my son. When you drive it for a bit it takes all the juice from the battery and will not restart for about a few hours and then will start up. It acts like there is not enough juice to turn it over. I have replaced the battery and had the alternator checked and both are fine.

Do the lights dim as you drive? Get a voltmeter and hook it up to the battery, star the truck, note the voltage at idle, then turn on all your accessories, heater wipers rear defogger, voltage should remain at 13.8 - 14.8. If thats ggod, your starter may be weak, the heat from the engine may be affecting it. Or the timing is advanced a bit too far.
