On my 86 Fiero with a 3.1, I mounted my battery up front. As for the cables I used, the positive cable is from a Riviera and runs from the battery back to the alternator. I have the ecm grounds grounded on the spaceframe, a ground running from the engine to the cradle, a ground runnign from the cradle to the spaceframe, and a ground running from the battery to the front crossmember. A few weeks ago, I noticed my positive terminal bolt was very white and corroded, but the negative wasn't. The actual terminal on the battery itself isnt corroded, just the bolt. This is a side post battery, and I haven't ever seen that happen before. Could this be because of a lack of ground straps? I'm thinking about adding a few more to see if it will help, but just wanted to see if anyone else has experienced this. Thanks!

if it's white powdery stuff, it is acid corroding the bolt. you may not have a perfect seal at that post, possibly from wrenching on it too hard. clean it up, and put some bearing grease orund the post where it comes out, and a little on the case right around it. before that you may wans to look carefully for any sign of a crack. while not permenant, the grease will ususally slow it down.
