Hey guys,
06 H3 adventure 120k on 37’s
Big cold snap finally killed my battery.
Replaced with no issue but Stereo won’t power on now.

Any ideas. Assuming fuses but wouldn’t seem like battery swap would blow fuses…?

thanks gentlemen

 

Probably got nothing to do with it, but dare I ask if you are still trying to use the crappy azzed OEM Battery Terminal Connectors?

May we assume you connected the battery correctly, Positive first, then Negative? The opposite order on removal. You can do a proper disconnect, wait 15-20 seconds, then proper reconnect.

Yes, a battery swap can blow a fuse/fuse(s) if there is an underlying electrical issue. Check the radio fuse and power to be sure.

 

Is it just the stereo not powering on?
Is it aftermarket? If so, check the fuse on the back of the aftermarket stereo or the inline aftermarket fuses in the wire harness.
