What is the average price to replace an alternator in a '91 Acura
While I was driving my car yesterday the battery light went on. So I drove it straight to the shop, and they said that it was likely that the alternator needed to be replaced. I'm curious how much this would normally cost so that they don't try and take advantage of me. He guessed just off the top of his head that it might be somewhere between $300-$400. That sounds like a lot to me......

Re: What is the average price to replace an alternator in...
The Part itself is from around $89.00 to $159.00. It just depends on the parts store and brand of part.
It sould not take a good mechanic more than 3 hours to fix. So I hope this helps you make your choice. $400 is definitely high. 1.5 to 3 hours labor.
Socket wrench set
Step 1:Determine that the new alternator is compatible with your Integra engine. Models built from 1985 to 1988 have a 1.6 L engine, 1989 to 1993 models may have a 1.7 or 1.8 L engine and models manufactured after 1993 will have a 1.8 L engine.
Step 2:Disconnect both battery cables with a socket wrench. Remove the four-prong connector and black wire located in the back of the alternator.
Step 3:Remove the adjusting bolt and mounting bolts from the alternator with a socket wrench. Remove the eight locking nuts and bolts with a socket wrench so that you can disconnect the alternator belt. This will allow you to remove the alternator assembly.
Step 4:Install the new alternator assembly and tighten the mounting bolts to 33 ft. lbs. with a torque wrench. Install the alternator belt and adjust it to the proper tension before you torque the locking nuts and bolts to 16 ft. lbs. Connect the four-prong connector and both battery cables.
Step 5:Reset the Powertrain Control Module idle memory. Start the engine and maintain 3,000 revolutions per minute until the cooling fan starts running. Let the engine idle normally in neutral for about five minutes with all of the electrical accessories off.
The brake master cylinder may need to be removed on some models pushing labor to the 3 hour side.

did you check that battery is charging with a multi meter ? could be that your alternator has a fault . Icheck battery voltage with engine off and running , voltage should be approx. 12.48v with engine off and around 14v running . if no increase in voltage when running brushes in alternator will need replacing .
Lead acid batteries can "die" catastrophically. This is actually not all that uncommon. If the battery is new, it should be under warranty. I would take it back, and have them test it. It it fails, which I believe it will, then there is the problem. If it passes, then your alternator is probably bad. The chances of it being your alternator are slim as you did jump the car off, and drive it for a while. If the battery is too weak to start the car, it will not maintain vehicle operation very long without help from the alternator.
