So I got my alternator rebuilt and now its putting too much current past around 2500rpm... im guessing voltage regulator right? The dash gets super bright every light comes on.. abs,airbag etc.. Oh btw this is a v6 5spd tour. Im just wondering cause the job was already all done and they told me everything perfect... who should pay for this. The company that rebuilt the laternator or the dealership.. or me?

Has anyone figured out this problem cause i just put an alternator in a few weeks ago and im having the exact same problem.

Check to see if it is really overcharging with a voltmeter. It shouldn't be getting above 14.6 or so. If it is hitting 15 volts or more when you rev the engine up it definitely has a problem. The voltage regulator is the most likely culprit. A flakey battery (sometimes hard to confirm) or a wiring problem is possible, but highly unlikely.

Doesn't your new alternator have a warranty?

So, did you have it rebuilt at an outside company and then have the dealer install it? Or did the dealer have it rebuilt and install it?

It also depends on what the problem is to see who is responsible to have it repaired. And, I would imagine that your rebuilt alternator would come with a 12 month / 12,000 mile warranty, but I reserve the right to be wrong...
