I have a 86 Jeep 2.8 V-6. I have noticed electrical problems. When the motors running if I plug in the cig. Lighter or turn on the heater fan sometimes my volt gage in the Jeep drops just below 12v sometimes it dosen't, other than that it runs above 12v to around 13+v. What would cause it to do that off and on? This problem has killed one battery and working on another. Alternator?
Thank You, CRITTER
