Are you are talking about a dual terminal battery? This battery can be used in a side mount or top mount configuration whichever applies.
You replaced the battery, is it good?? You really haven't given sufficient info. Check the Battery, Cables, Solenoid, Starter. The way I read this is that you put in a new battery and the truck's engine will not turn over when you turn the key. When you jump the truck, it turns over, starts, and runs. Are you jumping from positive to positive and negative to negative on the batteries OR are you going battery post negative on the vehicle giving the jump to a frame, engine bracket, or body metal point on your F150? If you are going positive to positive/negative to negative on the batteries, then I suspect your new battery. If you are hooking the negative jumper up to a ground other than the negative post on your battery, then I would suspect a bad negative cable. Speaking of cables, did you clean any corrosion off of the terminals when you replaced the battery? Corrosion does funny things. If in doubt, replace the battery cables.
To change the battery in a Ford (2005) F150 pickup truck - one needs to open the hood and identify where the battery is. It should be on the passenger side, right next to the chassi. You need to disconnect the positive and negative leads and unscrew the bolts holding the battery. You then can replace the battery using the same setup.
its connected to your positive battery cable.
Follow the positive battery cable from the battery, it will lead you right to the starter.
on the positive battery cable
It depends on what year and engine you have but, if you follow the positive battery cable from the battery, it will lead you right to the starter.
remove the negative battery cable for about 30 minutes
passenger side, on fender well by positive side of battery. ;)
Using a 5/16" 6 point box wrench or socket remove the negative battery cable first then the positive cable. Using a 13mm socket with a 10" extension remove the battery hold down bolt and remove clamp wedge. Remove the battery, clean up battery tray and cable ends with water and baking soda and wire brush. Install new battery, reinstall battery clamp and bolt. Attach positive battery cable first then negative cable. You will need to reset clock and radio settings.
Try jumping it off. If it cranks remove the + side on the battery. If it shuts off the alternator is bad .If it does not shut off clean the battery terminals . Have the battery checked at the Auto Zone.
follow the wire from the positive side of the battery it will lead you to it
Look at the battery cables, if the positive goes to the frame, then the entire sytem is a positive grounding sytem ,including the charging system. Mark Great simple answer Mark. This will also be of great help to you. An online 1941 Chevy Shop Manual. http://chevy.tocmp.com/1941shop/index.htm
