all you need to do is listen to hear the tank switching valve is working. It will make a soft noise under the rear cab section with the key on with the engine off. zif you do hear it sounding the switch your tank unit for that one tank you try to switch to is a fault. Sorry no illustrated diagrams are on hand, just knowledge

not hard at all, remove the driveshaft, undo the holding nut(impact tool helps a lot) you may need a peuuer to remove the yoke, pry the old seal out and gently tap the new one in, the refill the diff

Below is your wiring diagram. So does the battery run down or not? At 12 volts, the battery should run down. Here are a couple things to check. The grey 20 gage fusible link from the battery to the alternator runs the stator coil. You could try jumping that with a regular 14 gage wire to see if the voltage will jump up (should be at least 14 volts). The other thing is with dual batteries (which I think you have), if one battery is bad, it could pull down your voltage. Try unhooking the negative terminal on one battery at a time to see if the voltage increases. Let me know if you have any questions.
