2002 trailblazer. ..why am I not getting power after replacing wiring harness
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
Which one is the main fuse. .and to I am heading out now to look
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
I checked. My TB has a 125 ..my 05 Colorado has a 100..I removed the 125 and put the 100 I. It's place and put the 125 in Colorado. .Colorado started right up. TO still no sign of life. I used a old harness. .should I buy a brand new one
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
