2010 Acura tl shawd 6MT. I push in clutch hold down start button, and it takes about 4 seconds to turn on them displays check starting system. When I disconnect the battery for 10 seconds the problem goes away for about a day. Any ideas? Battery is fine. I’m hoping it’s not the alternator.

 

Does the battery light ever come on when driving around normally? I'd get a multimeter on the battery and alternator to see what's up.

 

what?
