Sorry again guys...didn't know what an OP was, but do now. I was watching for an answer til monday and then called the dealer. You were almost all right on. The dealer said when I pulled the jumper off there could have been a spike, but he also told me to clean all the battery posts and where the ground bolts to chassis. I did it all and have had no problems since. Thanks again, and sorry for not getting back to forum sooner. Seems like everything is crazy getting ready for the rainy season. scott
