The negative cable is only about a foot long and is connected directly from the upper post to the negative post on the battery.

Next , remove the positive cable from the battery . Finally, remove the battery hold down . This is usually a long bolt and metal plate, or it may be a strap , and the battery should lift straight out of the storage compartment. Be careful not to tip the battery over, or make contact between the battery terminals. Installing the new battery is the reverse process. Make sure to install the positive cable before the negative . This helps to prevent grounding out the positive cable .

I had this problem in the past, and only later found that the battery ground wasn't good.

Only one possibility though.
