As I'm making a turn and press the throttle to accelerate out of the turn the blower fan for my heater suddenly increases and the lights sometimes get brighter.

What is causing this? Is this an alternator going bad?

Thanks.

 

Could be that it starts to work correct and things work like they should .

Is your charge light on when this happens??

Could be the voltage regulator is causing it to over charge.

Could be you have a wire under the pedal or in the linkage.

A Multimeter is your friend

Say what that tells you.

 

Could just be a loose belt.....check the deflection on the belt to the alternator.....Buckaroo

 

Could even mean the battery is going bad. But I've had trucks that have done this all the time without any problems. See what the multimeter tells you but don't go looking for trouble where there isn't any.

 

Could also be the charge wire from the alt to the battery. Check for loose connection, corrosion up the wire under the connector. That is what supplies the resistance and a bad connection will cause the alt to overcharge.

Does the stereo cut out? Usually an overcharging alt will kick the stereo into protection if it's aftermarket.

 

Does it happen while just revving up the motor in the driveway, or ONLY when making the turn?
