(IMG:style_emoticons/default/WTF.gif) I complete the rebuild on the rear suspension and now the starter does not work. It does not make a sound...dead. I even installed the replacement starter I had laying around (high torque unit from pelican), and it does not work. What did I screw up this time? (IMG:style_emoticons/default/hissyfit.gif)

Andy is so right, but there is more! Batteries store a lot of energy and can be very dangerous.
Say you are removing the positive battery terminal with the negative hooked up still, and already have the bolt broken loose, but not quite loose enough. As you go to remove the wrench, it slips and moves over to contact ground. You now have the perfect storm. The wrench has about 400-500 amps running through it. Next you grab the wrench to remove it. It is welded and now you have a very serious burn to your hand. All of those amps have produced some serious heat! ALWAYS, ALWAYS remove the negative battery terminal first. I have witnessed this happening twice. Once the guy broke the wrench loose and saved the battery but received a nasty burn that took weeks to heal. Second time the wrench was welded so well to the chassis it could not be removed and the battery exploded. This was when I was a child and knew no better or I would have informed them to stop. I go even further. I have a special fully insulated wrench ( except for the end that fits the bolt) dedicated only for removing the battery terminals. Tom |

Tom I had this happen when I owned my first Karmann Ghia.....just barely brushed the wrench across the terminals while loosening the positive side.....I've never dropped a wrench so damn fast! Ever since that, I always remove ground side first and almost always remove positive also. I also watched in horror as an idiot friend of mine spot welded his meter probes to a live 220 line that was hanging bare in a building we were working in.....he got really lucky that he didn't get fried! |
