Duster should have been a DEMON! Cranking issues!

Replaced battery as it dropped to10 volts when cranking. Replaced lug end on cable from battery to starter relay and rerouted ground from k-framE to left framE rail. Had it out only once since these corrections were made and so-far-so-good! Now to figure why I have no power to hot side of dash light fuse! Thanks for everyone's help!
