03 Mustang GT (Parasitic) Battery Drain Fix

Hello,
I am seeing a lot of mustangs are having battery draining issues and I wish to share some simple solutions found while working on a friends 03 GT 4.6ltr.

In a quiet area, key switched off, hood up, Listen carefully close to alternator. I heard a high pitched hissing/whistle sound at low volume, came from back of alternator. This sound was the voltage regulator/rectifier staying on when key is off due to faulty diodes inside the voltage regulator/rectifier circuit, can cause battery to go dead after car not ran in about 2-7 days.

After having the alternator tested free at a parts store, test showed alternator was good because the faulty diodes in the alternator did not show up on the test, the machine did not test for faulty drain back issues that were present.
Alternator on-car-fix:

There was battery voltage running at all times through the two-wire connector on back of alternator. Disconnect the battery first for safety and to reduce chance of short circuit. The yellow wire/with white stripe is hot while car is off so I traced this from the 2-wire connector on the alternator then closer towards driver side front fender. Next I cut the Yellow/White Stripe wire, spliced a good connection wire to it and ran it through a hole in the fire-wall to the fusebox(under dash), connected it to a 15a fuse that does not get used but has power when key is turned on but no power when key is off.

The purpose for re-routing the hot wire to the alternator, is to turn off the alternator charging circuit when the key is turned off so it may not run down the battery. I am seeing good results with this fix(or patch) so far. No More Parasitic Battery Drain!

Another fix can be to change the small pulley on the alternator to a larger pulley so the alternator does not spin too fast, putting too much energy through the diodes can cause a charging system to act a fool. So if you have charging issues and have an alternator changed, putting a larger pulley on can make sense turn into saved dollars(especially on high revving engines).

I hope this info helps to solve some draining battery and/or alternator issues.

There's 2 fuses.
Fuse 5 is the right side
Fuse 7 is the left side
Both are 30 amp and are located in the fuse block inside the car. (drivers side kick panel)

The fuse block diagram is on page 167 in the owners manual.

it sounds like the speedo head in the instrument cluster is bad.
buy a used cluster on ebay

VSS only affects speedo when car is moving.

The problem may be due to poor grounds between the negative battery post and the alternator. The floating ground will cause the field voltage to be too low at times which will then not charge the battery and at times will also cause the voltage output to high (18 to 20 volts) which will damage the battery check the voltage between the negative battery post and the alternator. if this is not close to zero you will be in the same position shortly. by adding a ground strap between the battery post and the alternator bracket Poor grounds can lead to early failure of other things such as wheel bearings which are damaged by small arcing from the voltage differences between the drive train and the body while you are at it check all the grounds for poor connections remove clean and refit

I suggest that you visit the autozone.com website and register the car information. It doesn't cost anything and will give you access to an online repair manual for the car. The steps for replacing the alternator should be available there. Hope this helped and best wishes.

You know, I have a 2005 Mustang GT that honks randomly. MAKE SURE you troubleshoot it now. I waited and now my alternator is fried. About 95% of voltage disturbances can be contributed to the alternator, and from what I understand the alternators on our cars are notorious for crapping out. -Amanda
