Check the main fuse(s) in the under hood fuse box. Possibly when they were cutting the positive cable an arc occurred and blew the main fuse. HTH. -Jim

You'll see some large (maxi style) fuses. It'll be one of them. The main is usually a 100 ampere. It'll have the number "100" stamped on it. HTH. -Jim

Check the wiring down by the starter and your ground cable connections first. A catastrophic failure such as this is almost always in this area. That's where power from the battery comes in at. HTH. -Jim
