Wrong jumper cable intallation

Motor Vehicle Maintenance & Repair Asked by Augusto bantatua on December 5, 2020

I have a chevrolet captiva 2010 diesel model. The mechanic installed the jumper cables backward. My suv doesn’t start anymore.(it doesn’t crank) What could be the problem? What should I check? Thanks

@Paulster2 is right in that more information would be helpful, but first of all, the problem is that you have a terrible mechanic. No proper mechanic should get the connections wrong for jumping a cap.

That aside, wiring your battery wrong is likely to kill the battery (essentially, you've shorted the battery, and it likely hydrolyzed the water in the battery). Simplest check is to swap the battery, or try jumping correctly from another vehicle. If it still doesn't start, you may have a bigger problem.

cars/trucks have a main fuse, if you trace the positive cable it will lead to the fuse box. you will probably see it going into two 50amp fuses or a 100amp fuse. if the fuse is not blown, then the wire going to it probably is... a simple volt meter continuity(beeping thing) test between positive battery terminal and the fuses will reveal where the wire is broken.
