in Dec my dad passed away

Im now working on his heavy equipment so that we can sell it, his 1981 dump truck has a problem with the charging system. the alternator is working as I get 14V out but its not reaching the battery's. I was wondering if someone here would have an idea where the fuse/breaker would be that is interrupting the flow of power. the truck starts just fine. so its just the charging
also I looked this up on autocheck and got this info - is the truck a C7d042?
Im asking so I know what to look up later

VIN: 1GDM7D1Y0BV58XXXX
Year: 1981
Make: GMC
Model: Topkick C Series / C7D042
Style / Body: Conventional Cab
Engine: 10.4L V8 Diesel

Thanks
