[QUOTE="Drillerguy, post: 431016, member: 19788"] I have a 1990 YJ with the 4.2L inline 6 cylinder engine. I installed a shiny new 3 row aluminum radiator with electric fan, the fan burned up in about 15 minutes. The company that i got the electric fan from replaced it. This one also burned up in the same time frame. After checking around, the alternator is putting out 15.3 volts. Thinking the internal regulator was bad, I replaced the alternator with a "new" rebuilt one, this one also is putting out over 15 volts. No other electrical issues. What am I missing? Thanks [/QUOTE]
