The alternator in my '91 4.0 has been giving me some trouble lately. Whenever I start the Jeep, and sometimes going down the road, the volt gague drops to 10-12 volts. While wheeling last weekend it got lower than that and the vehicle died. But, if I get out and use a bar and a hammer to smack it, it starts charging again. I have also had it jump back up after I hit bumps on the road. Has anyone else had this problem. I'm thinking voltage regulator. These are internally regulated, right? Is there something else I'm overlooking. I don't want to drop the $$ to replace it before I persue other options.
