Okay, Just got this jeep. and some times this will happen, it starts after cranking it for about 10-15 seconds, the alt is dead or not working, but the batt is fully charged. (i charged it) well as soon as i turn the key off from running it, the tach will climb to 1,000 - 1500 prm also i have noticed the emergency flashers are VERY slow unless you play with the switch, if you only push it in a little then they flash normaly. and also if you have the park lights on, the left hand turn signal light comes on Very dim (you can only see it at night with the guage lights turn off or way down. any ideas? it's an |6 4WD. snow is comeing and it will by my only way to get down our mountan to work.

Okay, the first thing to check is to turn on the signal on one side and see if the outside signal light comes on. if the light comes on then try replacing the flasher. Also see if your 4way flashers work or if they are also out. if they are out then check your fuse first. If the fuses are good then try the flasher, if the flasher does not solve the problem then you may need to replace the turn signal switch. I have worked on a few of these and most of the time it was a flasher or the turn signal switch. good day.
You will find that there are two flasher units on the fuse panel. Turn on the four ways to identify which flasher serves that circuit. Then, move the flasher to the other position (where the signal flasher is) Your directionals should then work. You then can buy another flasher and install it when you have a chance, putting it in the 4 way position. The 4 ways get used so infrequently, you always have a reliable spare signal flasher there!
OUCH!!! If there was no previous wiring problem, first check that you did not inadvertently ground a hot wire somewhere. Then check the starter & solenoid for internal shorts. (Ive seen some wierd stuff along the way, including a brush assembly that broke and the spring shorted out an entire starting system). Unfortunately, you will have to cut open the wiring harness and replace all burned wiring. Be careful to seperate any fused together wires without breaking them. Use the same gauge wire when repairing, to avoid overheating of new stuff after repair.Wrap wire ends together, then solder all connections. Squeze type junctions do not work all the time. good luck
