My son has a 2003 CRV and every couple of months I get the call "dad, the car won't start". Battery was replaced about a yr ago, and exchanged for a new one about 3 months ago. Got the call again yesterday. Got to it, jump started right away and got it home. It sat all night, this am checked voltage and battery tested fine, and car started right up and voltage went up running so gotta assume alternator is fine too. What else am I missing??
