94' F150 new alternator making gauge read backward??

dmiller · Nov 22, 2010

I put a new alternator on tonight. When finished the gauge reads backward. Will not start (assume due to the cold 3 degrees while I was working on it. Have to get it done, have firewood to deliver and need to get more pig feed).
While cranking the gauge reads - amps.???
Any ideas???

thats what its supposed to do. not gonna show a charge till the engine starts!
and its sure not due to -3 either, its -31 here and havent started truck for 2 days and i can go out and fire it up if i need to without being plugged in. must be something with the F in it.reminds me of the commercial on tv a few years ago, the two old guys say "its all ways been ford" are they talking about trucks that dont start?
