I have a 2005 with original altinator. Gauge bouncing around last night while driving (12 amps-14amps) and interior,floor,underhood lights dimming. Today I ran it for 30 mins in the driveway and it held true at 14amps....bad ground,regulator or is altinator getting ready to cash out? Thanks.

First of all it's alternator. Second it's volts, not amps. And third, I'd have the battery load tested first to rule that out.

^This^, then built voltage regulator.

Battery is brand new,but will check it.....and thanks for the non-******** ^^^ response.

Correcting your mistakes is "********"?

It came across belittling...

Most every chain auto parts store, Interstate Battery dealer, etc, will do a free system check for you. I retired from the battery business, so I have the equipment to check it, but it would be a bit of drive. Ground is always a real possibility, but I would start with one of those system checks, if it says the alternator is bad, check it off the car, to confirm.

Batteries are far better than they have ever been, but you never know!

if you have a good rebuilder in your area your just about due for one.the builder I use and the units come back as good as a new one from GM

I have the same issue on my 2006. Took off the belt and spun the pulley and was able to hear the rotor in the alternator nicking the stator or case inside. Getting the alternator remanned this week. Easy to remove belt. Get a socket crank the tensioner over to loosen the belt to slide it off.

I've been planning to upgrade to a "Billit tech" high output unit....but wanted to wait til it's needed.....maybe now is the time! Thanks!

EVRose

Sorry, that wasn't my intention.

C U IN REARVEIW

Check your connection at the starter solenoid.

Also check the ground cable.
