hey guys im new to this site. ive used your forums to answer some of my problems in the past, so i was hoping you can help me out with this one.

i have a 92 f350 dually. 7.3 non-turbo, auto 2wd

i just recently installed a new alternator and ever since then when i start my truck my wif and wts lights glow at about 50% brightness and my amp/volt gauge stays high. (at the "a" or "l")

the truck starts fine as usual in warm days and really cold days (35-70 degress)

any help would be great, thanks.

 

Maybe a short or moisture in the computer?
