The regulator is inside the alternator. Get a new alternator or disassemble the alternator and install a new one. My option is get another alternator.

After driving long enough to get to operating temp if I shut it off and then try to start it ithin 10 minutes it acts as if the battery is dead. won't turn the starter but battery shows full charge an


To recharge the current taken out of the battery during start up requires at least 10 -15 miles driving. Driving less than that, progressively drains the battery available power until it has not enough power for another start. Such a battery "resting" for more than 10 minute might regain enough power for a start but is inherently flat. Put it on a battery charger for at least 12 hours or go on a 2 hour or more drive. It should be OK for quite a number of starts even when doing short distance driving. If it is showing the same symptoms directly after to 12 hour charge/drive get the battery tested at a garage or battery dealer who will be able to tell if the battery needs replacement. If the battery test OK there might be bigger problems like a blown top gasket or problems with the starter motor.

A red light on the dashboard can mean you should stop driving right away, or you may have a little time before you have to bring your car into the shop. Know what's what so you don't get stuck.
  1. Critical Warning Lights
    • 1 Brake Light. Make sure you are not driving with hand brake on. Check brake-fluid level. Top off brake fluid if low and make appointment to check brakes. Driving with brake light can be dangerous; deal with this soon. Call tow truck or drive carefully and slowly to shop.
    • 2 ABS (antilock brake system) Light. Indicates either low brake-fluid level, stuck brake caliper or faulty ABS. Check brake fluid and make appointment to get brakes checked. Call tow truck or drive carefully and slowly to shop.
    • 3 Oil Light. Either engine is very low on oil or there is no oil pressure. Pull over and turn off engine immediately. Check oil level and add oil if low. Turn engine back on to see if light has gone off. If oil light is still on, bad oil pump (no oil pressure) is likely. Call tow truck.
    Maintenance Lights
    • 1 Check Engine Light. Car's computer senses engine problem. Difference in performance may not be noticeable, but make appointment to have car diagnosed. This usually cost around $65-$75 to do. OK to drive. If problem is serious, computer may switch to limp-home (low-power) mode and you won't have option of waiting to bring car into shop.
    • 2 Air Bag Light. Get air bags checked. Problem could prevent them from activating in accident. OK to drive, but not safe in accident.
    • 3 Battery Charge Light. Alternator is not charging. OK to drive, but turn off any unneeded electrical devices (radio, heater, defroster) and avoid starting engine more than necessary. Bring car into shop soon to avoid getting stranded. When alternator is not charging, battery loses charge and car stops working.
    • 4 Emissions Lights (O2 sensor, EGR, check emissions). Depending on car model, these lights may indicate problem with emissions sensor or may light up at certain mileage, usually 60,000 miles (100,000 km). Get sensors checked. OK to drive. If problem exists, car might get poor gas mileage.

My spouse had to get out 1996 ford explorer boosted while i was at work,so that evening i tested the battery it had a charge of 12.4 and is about 5 years old so i bought a new battery ,i put the new...


A new battery should have approx 12.62 fully charged
It could be slightly more
If you ever see 13 volts, on an old battery, it is gone

You need a min of 12.5, to do any testing of your vehicle, or you charge it
It should hold 12.5 or more for 3 or 4 weeks,then charge, if you let the truck sit
unused.

The battery, which is new drains and does not charge during each use of the vehicle.


you need to check the charging system with a multimeter ,start the vehicle and turn on the high beams and the heater fan to high,and put four ways on,now check what voltage reading you have at the battery post,it should not even be lower than 12.5 volts.

Starts with boost then car dies after 1 km and won't start


once the car is started it runs off the alternator .. so even if your battery is bad the alternator will still run the car .. so it looks lilke your alternator is bad .. when you jumped the car you charged the battery a little but not enough to keep it going since the alternator is not charging . if you hook up a charger overnight then you might be able to run it long enough to get somewhere (garage) .. try to drive when you dont need lights .. those will run down the battery in a short time .. if you have a volt meter then the battery should read about 13.8 to 14.2 volts when the alternator is working properly (car running) .. if it reads lower (like 12volts or less) then the alternator is not charging .. some auto parts stores will test your system free ..
