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.

My 97 accord has always ran with no problems. I recently replaced the battery and it started and drove fine for 3 months. After not driving it for 1 week, the car is dead, not even an inside light and...


If the battery is completely dead, you'll need to slow charge it for a few hours before trying to use a jumper battery. And you could have something shorted to ground in the car that drained the battery in the first place.
Try disconnecting the battery cables and using a battery charger to bring the battery back to life first.

If i keep the negitive connecter on the battery it will go dead in a hour there is not a wire hooked up on the alternator but i dont know where it might go?


Even with the wire removed, are you saying it goes dead while driving or just sitting . if it goes dead wile driving then the alternator may not be charging the battery as you drive but if it goes dead while the car sits then there is a draw some where.
if you sent me the year make and model with the engine size and also let me know when it goes dead in 1 hour, while driving or car just sitting and i will help you solve the problem. good day

While driving, successive loss of power culminating in the engine dying. Lights still working but engine would not start. After 5 minutes everyhing dead. 1 hour later engine starts and works for less...


Sounds like it could possibly be a bad alternator if all the cables are tight and started out with a good battery. Do you have a battery or red charge light? Or, alternatively, is there an absence of this light when the car ignition is on, but the car has not yet been started?

Good luck on this repair.

Battery going dead 2001 BMW 330i


Whenever a car has this type of a problem, it is normally because of poor connections, belt slippage *severe*, or - very possibly, something is putting an excessive drain on the battery when it is not running.

My experiences have been to first check that ALL the connections are totally clean - especially check your battery posts and make sure they are tight with very good - surface-to-surface contact. Remove BOTH connectors on the posts and clean with battery post cleaning tool *wire brush* and then use the spray that stops / limits corrosion.

Are you sure that battery IS OK? Take it in for a load test - old batteries often deteriorate over time *sealed or not* and it just might be time for a new one. Get the biggest 1 that will fit in where it is held. More amperage *rating* is always better.

Poor connections often happen during cold weather season *expansion and contraction cause this*.

BAck to connections again - VISUALLY inspect ALL your cables/wires for discoloration. Connections need to be tight - end-to-end in the charging system. I am not sure if the car has a starting relay or not - and if so - where it IS located. THAT TOO is a problematic area due to poor connections that quite often, just may need to be cleaned.

Are you sure your alternator IS good --- are it's belt nice and tight- but not too tight? Speaking of the belt ... look on the inside track of the belt - has it been replaced recently or is the rubber in poor shape *splits, showing sign of extreme heat from slipping etc*. When you have a load test - that test alone will indicate whether it IS charging even if everything is running like A/C, radio, light, wipers. Check you gauge inside the car - IF it has one - and no matter what RPM ~ it should still be charging *showing positive charging - NOT discharging*. Lastly - the alternator OUTPUT -- is it the right one for that car - correct rating???

There are even more areas worthwhile checking ... but unless you have the correct tools and diagnostic equipment - it can be tough to nail-down the right specific problem. A lot of places *like Sears* will have that - and used to not charge for the diagnostic - because they wanted to sell you THEIR battery.

One more thing .... most cars will have some minor drain due to clocks running, alarm working and so on. HOWEVER - if a light *like an interior or truck light* remains on, that will give you a larger drain.

A battery should never go dead while driving - and your light *running lights* should always be bright .. are yours??????

Hope this helps!
