Hello! First post from an H3 owner here in Tennessee! My H3 has an aftermarket audio/video system with 5 monitors and recently a battery was connected with reversed terminals My alternator was replaced along with a new connection from the battery to the alternator. Before and after the new alternator my audio is out! My doors and seat belt chimes can still be heard in the vehicle! I've had my dealership look at the vehicle with no solution...does anyone have any ideas on how to get my audio back? My receiver seems to still be fine, lights up, can turn the volume up, but no sound! Is there a fuse that could be responsible? or a blown amp? Any help would be greatly appreciated, looks like i'll be fixing this issue myself hopefully!! Thanks for reading! Glad I found the forum, I have a lot of improvements to make with my H3!!

 

Does it have aftermarket amp or amps? If so, they have their own fuses that are toasted. Possible the power wire to them is toast too.
