Yea^. I cleaned and added grounds myself. I guess if you have a big blue wire going to the big lug on your starter relay. That's the fused link where the alternator power comes into the system. I've never had trouble there, but if that were getting hot and or not connection well, of course you would end up with low power. Here's some diagrams...for what it's worth! > http://www.scribd.com/doc/11033020/Jeep-Cherokee-1989
You are sure your belt is good and tight? Voltage is the first place it shows when mine is loose.

I have an 88 as well mine does the same thing but no loss in power, I checked all electrical connections, battery and alt is new, it's just the gauge, if you replaced or saw that it was has good charge I wouldn't worry about it

Yea, that ground cable from the battery to the block if supper important. (as well as the braided cable from the back of the head to the firewall)
Besides following Cruisers info, I was pointing out that that Positive power wire from the alternator, goes to the big terminal on the starter relay. There it meets the wire to the battery and fans out all over the place. While you are there you might put your meter between that and the block, and see that that connection is good as well as the grounds. (what I meant is meter the VOLTAGE, from there to the block)
