The other day i get in the ridgeline to leave for work and I see the battery light is on. No noticeable loss of power when starting or driving the truck. I then drive to work but take it to Advanced Auto on lunch to test the battery and Alternator, with both coming back good at around 14v. They advised to clean my terminal (it was a little corroded) and offered no other info as to why the dash light it illuminated. I clean the posts/terminals and re-connect, no change. I take it to my family mechanic who also confirms good battery and alternator plus check all other connections and fuses.He doesn't know why the light is on.

Has anyone had this situation and if so how did you resolve it? I've driven it like this for a few days without issue however i dont want to get stuck somewhere if there is an underlying issue. 132k on the odometer 2006 RTL

 

Check all the fuses.
Then check the wiring from alternator.
Could be wiring is rubbing against something which causes this issue???

 

Just for giggles pull codes and see what you get.
