well, last night i had my truck parked at a friend's house for about an hour and a half. i come back out to get on my way and it's completely dead, no light, no radio, nothing. it took us about an hour and a half to jump it and once i was driving it would completely shut off, headlights, no power steering, etc. all of the sudden it would kick back on and did this 4 or 5 times within 2 miles. i get about 3 blocks from another friend's house and it dies and won't kick back on. after about 30 minutes of trying to jump it, it kicks back on. once it gets started the needle in the speedometer fluxuates between 5 and 30 mph until i start going. the abs light also blinks the entire time. all of this happened again this morning except for the losing power and regaining it while i'm actually driving. i do sort of have a bad positive terminal but i can't see that being the entire problem. could it be that or alternator or what? any advice or input would be appreciated.

'01 2wd edge, 3.0 auto just in case.

 

make sure all connections-including bad battery terminals- are tight and free of corrosion because this may have alot to do with it. After you eliminate this problem then try, but yes it sounds as though it could be a bad alternator. How many volts does it put out while driving-if its between 14-15 then you should be alright-if much lower than that than the alternator is not charging while you are driving

 

Yes if it has a bad connection or your intermittently loosing connection it can. It can also cause your Alt regulator to blow. You can try checking for Volt drop (bad connections) If you have a volt meter (with the engine off and Bat charged) hook the Pos lead to the Pos terminal of the Bat and the Neg lead to the Pos cable connection at the BJB block and then at the B+ term of the Alt. Anything over .5volts is an indication of a bad connection. Do the same at the Bat Neg post except switching the leads so the Neg lead is on the Bat neg terminal and the Pos lead is on the Alt housing. Again anything over .5 volts indicates a bad connection. You might also try wiggling the cables while doing this check.

 

when i pulled into my driveway today and turned her off, it was completely dead. and when i drive my volts read right in the middle(not sure how many that is) but are good. i had my door open replacing the terminals and as soon as i got them both hooked up the light came right on. hopefully this does the trick and thanks for the input guys.
