What's your voltage at idle? Watch alternator output as engine speed gradually increases.

About 12-13 volt

You should be reading 13.7 to 14.7 for a good alternator, have it tested, most auto parts stores will bench them for free.

Sorry I read it wrong it idles at 13.7, & sorry I just joined this ford forum & still trying to work it out

You're still on the low end, it might be worth having both the alternator and battery checked, it's free and rules out an electrical supply problem.

I just put a brand new battery in it.

Ok, have the alternator bench tested., since they do it for free, having the battery tested is still not a bad idea. I've seen batteries go in 6 months... because of bad alternators.
