    Went out to fire up the mighty K5 for the afternoon road trip and it's dead - popped the hood to check the battery, and it's swollen up to the size of a basketball, and the positive cable is missing about 4" of insulation - but it's not touching anything - anywhere. So anyone have any idea where to start looking for this @#*&ing short?

    Sorry man, that's a bummer. I would start down by the starter, where the positive cable runs from the battery down to it...Looking for bad insulation, wire rub etc etc....

    It may not be a short at all. I used to work for a forklift battery company. Is is very possible that either the insulators between the plates has worn thin and grounded the plates together, or that during the process of constant charging and dis charging it has shorted its self out. Everytime that the battery is charged it dis spells some og the lead in the plates, when it charges the electolite is absorbed into the lead like a sponge. After a while there will be a sediment that forms in the bottom, and over time it cin build up to "connect" 2 or more of the plates togerther. I would start there first. I always have to remind myself....KISS...Keep It Simple Stupid! I often times over think something and overlook the obvious. You also might want to check the Battery cables, and make sure there is not a short or a hight resistance in the cables.
    Let me know what you find.

    Pugs,

    I'm with these other guys....it may just be a spent battery. BUT this does give you the opportunity to upgrade the "flimsy" cables that may have been on your battery to something big and beefy, and also a chance to clean up the frame grounds that are probably rusty and in need of some attention.

    Remember, the negative side goes to the block, and then to the frame....I've seen plenty of older vehicles where part of that ground system was missing or improperly attached.

    BTW-&gt; It probably wouldn't be a bad idea to add an in-line fuse to the positive lead if only temporarily to confirm that you DON'T have some kind of major short in the system. Once everything is checked out you could decide if you want to leave that fuse there or not.

    Good luck and let us know what you find.

    Found it!![​IMG] Big time cable resistance - It's just broken and corroded all throughout. Don't know why it waited till now to quit though - It's been working fine for the last 2 months. Oh well, I guess I needed an excuse to convert to 2AWG top mounted cables, and an XP31 battery, and now I've got one. Thanks guys!![​IMG]

    Only trouble I've got left is the logistics of carrying a 75lb battery, and a set of cables the 2 mile walk home from Napa - got 2 trucks here, and neither of them runs[​IMG]

    Most NAPA stores have delivery trucks. I'll bet if you asked them really nice they would bring the parts to your house. [​IMG]

    If you get two batteries it is easier to carry them because you will be balanced much better. You can drape the battery cables (for your new DUAL battery set up) over your shoulder or around your neck. The new battery tray for the second battery comes in a box and is fairly stong so you can play a game, like kick the can with it and get it home in one smooth trip and have fun doing it!!!!!!

    Ya know, I actually thought of that!![​IMG] I ended up coughing up the $10 to get Napa to deliver everything, and after waiting around on them to deliver a ground cable that was actually the length I ordered, got it all up and running and it's great!! Now all I've got to do is find some heat shield sort of stuff to keep the hot cable from getting baked by the header. $122.85 for the battery and #2 cables total - not a bad deal if I do say so myself[​IMG]

    ......And knowing is half the battle
