Question about 1993 GMC Sierra K1500
My Sierra doesn't charge the battery when its cold. If its above about thirty outside its fine. Any colder,15 to 20, then it doesn't charge until the truck warms up. It charges fine once the truck is warmed up.
Sounds like the alternator/regulator assembly is getting weak. The cold wreaks havoc with electrical equipment. Probably need to replace it prior to failure. Hope this helps.
