I have a 89 jeep wrangler and I cannot use my headlights, turn signals, and stereo at the same time without my electric going crazy and shutting off my engine.
With only the car on and stereo the electric gauge reads about 14. I turn on the head lights and it goes down to 10-11. When all three are on, it goes down to 8 and under then the car starts to shake and dies. There is a brand new 140 amp powermaster alternator and a new red top optima battery.

chilton / haynes manuals should have a full electrical schematic in either.... if you do not want to buy then you can go to almost any local library and make a copy or just check it out.... hope this answers your question.....
Two things I'd look at there...First, though it does not often happen, I'd check all turn signal bulbs to make sure that one of the filaments have not burned and re-connected themselves to the adjacent one inside the bulb. Second, you will need to do a visual check of the switch itself, to make sure the internal contacts have not melted and are not shorting to each other. Only other quick test is to remove the four way flasher and plug it in where the one for the turn signals is. If the one for the signals is burned, it possibly could do that as well. (both flashers are the same) On an 89, there aren't any "modules" so it's a fairly simple system that should not be difficult to diagnose. Most turn out to be the switch under the steering wheel. Always make sure that all bulb sockets have a good ground. Good luck
sounds like a battery or ground connection problem , disconnect and clean the inside of the battery cables and the posts,tighter securely . If that doesn't do it remove the other end of the negative cable and clean the cable end and the metal that it bolts to.
Hello, We used to have this very same problem with our Mini! what you have here or havn't as the case may be is a good Earth to the Engine Starter and Battery so your cables are doing an overload job. Take an extra earth strap from engine/starter direct to battery!
