Its possible you bought a bad battery, make sure your connections are good at the battery and starter. Make sure the battery is grounded. With the lights acting funny sounds like you have a bad ground.

Van wont start .checked alternator. fuses and brand new battery still wont start. van started acting u when fuse to rad fan went out. engine light came on but since we live in cold area never heated up....


I think you're over your head here. Take it to a professional mechanic and let her sort it out. Sounds like your alternator isn't putting out the correct voltage.

No power and batt is good


My first guess would be a dead cell inside the battery, or a blown fuseable link between the battery and the fuse box.
Someone would need to check the battery connections and fuse box with a meter.

We have a 2002 Grand Cherokee that we have just bought. Dealer installed a brand new battery because of sluggish starts. In a week the battery is acting weak again, sometimes it starts fine, other times...


I was having the same issue with my 95 GMC. I replaced the battery and alternator. It would start fine at times, at other times it would be sluggish. I finally took the starter off and had it checked. Turns out the starter was bad. When it would get hot, it would act as though the battery was dead. Replaced the starter and it has not acted up again. Have the starter checked. Replace if bad.

Im having trouble starting my jeep when it starts i have to give a little starter fluid and it will run fine but acts like it starts loosing power truck eventually dies and when i try to start it turns...


I'm sending you a wiring diagram so you can get an idea of what your wiring routing is like. What I think you have is a regulator not inside the alternator but inside the computer. Therefore replacing the alternator will not help.
Charge the battery and have it load tested, then check the charging system. You should have at least 13.5 volts running. if not, check the wire between the battery and the alt for power. The computer sends a ground signal to the alternator through the black and white wire (check that on diagram...I'm doing this from memory) If you ground that wire the alt should charge the battery. DO NOT leave that wire grounded as a fix or it will boil all the water from the battery and turn it into a brick! If you find that works, and the wiring is intact, replace the computer. Usually you can find one at a reasonable price in a scrapyard. find the diagram at: http://www.scribd.com/doc/18999822
