broken motor mount = broken alternator
96' Cherokee sport 4wd 6cyl 4.0 250,000 miles everything under the hood is stock.
So I am leaving for a hunting trip, and wanted to do a check up on the jeep so I could make the journey. While under the hood we noticed that the motor mounts looked worn out. We put it in gear held the brake and rev'd a little. Turns out when its in reverse the passenger side motor mount is completely broken and the engine lifts up. the driver side is worn but still functioning. So in our test of looking where the mount was broken we had to torque the motor a couple times to get it to raise up, not extreme just enough to see the movement. Got the problem figured out and made a plan to fix it. On my way home I noticed the battery gauge was a slowly dropping. I got home and checked for loose or broken wires, possibly from the engine lifting and pulling them loose. I did not see anything. This morning the battery was almost dead, dim lights no power locks etc. I was able to make it to work without lights, but as I pulled in the gauge showed completely dead. So the alt is either not charging the battery or there is a problem with the battery. I just think it is to much of a coincidence there would be an electrical problem, right after we found the broken motor mount.
so my question is, what do I do? I have a solar battery tender on it now while at work, so the battery is charging. I will be able to make it to an auto parts store to check the alt and battery, but I personally don't think it is the problem. What do you recommend I check first?
Any help is appreciated, I leave for an elk hunting trip... as soon as my jeep is drivable.

Yes go to an AutoZone and have them check the electrical system they can do it all from battery to alt. Then you will know exactly what it is and repair it. The mounts affecting this....possible but not likely IMHO.
As far as the motor mounts I would replace them along with the transmissions at the same time, you wait on those and it "WILL" end up costing you a lot more money. Like for a radiator, fan, etc. plus your stranded wherever you may be.
