It will be hard to tell what amp the gen. is because if it is 12 volt it is not the original gen to the truck. 25 amps would be Sufi chant unless you have added some accessories. Less amps then the gen. was designed for doesn't hurt anything. Don't use the truck till it is fixed like Otto says you can damage the bat. & any thing electrical on the truck.
Now would be a good time to change to an alternator.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
