Good fix

I hope you used a fusible link when you "jumped" the old link. If not you don't have the protection of a link - the next weakest component will be your "fuse".

Hi folks, i just picked up a multimeter and have about 12.7 at the battery after trickle charging all night. start the motor, then one side on the alternator and i get about 11.6, which i believe should be about 14.4. Belt is tight, and it appears to be spinning. Is my best bet a new alternator?

Ford Technical Service Bulletin 04-14-9 says:

DCT Code P0320 with possible drivability concerns and/or charging system warning indicator on with possible DTC P0620 -

Corrosion or damage to the 14305 harness or interaction of the PCM with the charging system.

*Reprogram PCB to latest calibration ($85)
*Replace 14305 harness (alternator to battery harness with fuseable link) ($57)


I replaced the alternator as well since I was only seeing 11 volts at the top of the battery and 11 volts at the top of the alternator.

I also replaced the battery in case there was a bad cell.

Everything runs fine.
