I swapped the battery connectors, went with military grade, crimped ends, clean job, grounds are clean. Southern car, nothing corroded (that I can locate).

I had one reboot of the radio/HVAC right after the battery connector installation, and none since. I suspect, I have a gremlin or the app radio I installed (Boss app unit) may be an issue, it does reboot, and lock more than I care.

Thank you for the great suggestions, I will keep an eye out for further issues and the gremlin.

 

Did you use a plug and play adapter or hard wire each connection?
Plus, Boss Audio is about the lowest grade car audio you can buy and have been known to cause electrical issues and drains in many, many vehicles.

 

I hear that, thought this Boss would be ok, my primary requirement was hands free phone and backup camera. I used the recommended adapter, Crux SOCGM-17C with Solder Seal Heat Shrink Butt Connectors.
