wats up yall. My alternator broke down too so I was wondering, I know this guy that has a junked up 2001 ford Explorer with a 4.0 same engine as the the 05 mustang sixer that i drive. You think if i swap alternators it would function properly. would they produce the same amps and sh!T.

Do you know if they are the same part number? If not, I am sure there are a number of online resources that will list part numbers for each and you can compare. Or if you are able, just go look and see if there part numbers on the alternators are the same. If they are they should have the same output.

Autozone or advanced auto can check your batt & alt. Its one of the two.... No big deal, I would put my money on short in batt. Good Luck

Have your alt rebuilt 35/60 dollars.....Get a new batt.

So long as it does as many amps or better, your ok in that respect. As BigDinTexas states you can just look up the alternators via the part #´s and see their rated amperage. Being able to produce more than stock is a bonus. Just don´t want to be under the original.

As for fitting, that someone else will need to chime in, as I´m unsure if the fittings and sizes are standardized in any way.

Its not so much the voltage has how many amps when load testing! Have seen many batteries that are 12.5 volts and once you load test them drop to 5v or less

OK, took mine to the dealer this past Monday and guess what? The alternator was not charging the battery. Duh! I told them that on the first visit. What helped me is that I bought one of those little monitors that you plug into the 12V accessory outlet in the middle of the dash and watched it as I drove. Stopping at red lights and stop signs caused the voltage to drop below 12V. I relayed this information back to my service guy and within 2 hours they had it fixed. I had the extended warranty so I only paid $100 instead of $261 for the alternator. I tried to look online for a replacement voltage regulator for these but did not find any listed. Apparently they don't want you fixing these and would rather have the whole thing replaced.

Good to hear they finally got it resolved for you.
