Need Hepl Please!

Friend tried to jump my H3 usin a battery charger and accidentally had it on the 24v boost setting! Nothin is working now and car won't start! :( I figure I have damaged the PCM and probably blown my speakers among other things. Any Hummer mechanics/afficionados out there that can tell me more about what damage I'm probably lookin at and cost to fix? :confused: Thanks.

First thin to do is scan all modues for codes and see if you can communicate with them all, if not check power and grounds to modules, if ok you need to replace any modules that wont communicxate. also check all your fuses and replace any that are open.

Have you tried a new battery?
