Chrome FORD Mustang GT High Output Alternator 140A I keep getting the P0340 code ,used the search function and it seems my alternator is going to go on me, anyone think this is 1) worth the $$$, and 2) would it fix my problem or should I get the PA performance one. my car has stock radio/speakers, so no need for the 200 amp for me . thanks for the thoughts on this.:thumb2:

If you can park the car for a few days, you could consider getting your stock alternator rebuilt. Apparently the regulators are known to fail and are easily replaced. I chose to go the PA Performance route, though.

If you can take the back off of your alternator, you can replace your regulator if you think that is the problem. Here I show how to install the new one (the old one has been taken off).

Position the voltage regulator/brush holder like this:

Use your finger to depress the two brushes like this:

Put the unit on top of the bearing and start it down the shaft while keeping each brush pushed in until you can let go.

Position the voltage regulator/brush holder over the 3 screw holes.

Re-install the three T-20 torx screws:

This is in the DIY section under my user name.
