I just put a new engine into my 2006 Pilot. A new alternator was installed along with it. New engine runs great, but my battery warning light just came on. I went to auto parts store and they checked battery and alternator. They said alternator was fine (not surprised) but battery failed. I replaced battery and warning light is still on. I've driven it for 20 miles or so since the warning light came on, no signs of bad alternator, battery is new, what else could it be? Any advice is appreciated. I did notice a corroded engine ground strap which I plan to replace. Not sure where else to look.

Check all you cables for rust, looseness or corrosion, including at both ends.

Check cables from battery positive, battery negative, and connections to chassis from the engine block. Beyond what has already been mentioned by others it could be loose or corroded wiring.

If necessary, you can get pretty good ones for not too much at Walmart.

Just picked up the $3.96 19” six gauge cable to replace my broken ground cable that never triggered an issue ;) View attachment 137171

After engine replacement, this is very likely the cause. Ground cables could be disconnected or missing.
  1. Battery to frame
  2. Engine/starter to frame
  3. Transmission to frame

So if the OP comes back and says that's not it. What are we going to suggest then? 🤔

Their sacrifice was not in vain. Their legacy lives on.

I reckon ya done scared him away for good. Happy Halloween.


But if he be so brave and courageous that he dareth come back, checking connections and checking the voltage would be the tricks that might do him a treat.
I'm completely knackered working these treats. Lol

I hope I didn't scare them away. Maybe we didn't respond fast enough and he got the answer somewheres else?
