2006 Ford Focus 3.2L with codes P0625 and P0626. When cold out the car won't start?

Question

The car was running fine until last week when the temp reached the low 20's and teens then car wouldn't start or would only start sometimes. Kinda like hit or miss. Took it to a buddy and got p0625 and p0626 codes. Generator field f terminal circuit and generator field f terminal. I am lost with this and have no idea about it. Any help would be appreciated.

Answer 1

you will have to check the battery and the charging system. Its possible the battery is bad/or not of quailty. Expensive batteries like Optima batteries have a higher cold crank amperage

Answer 2

This code really does point to an issue with the alternator. Especially under a load like when you start the engine.
