Wife's 2006 Focus ZX5 automatic died yesterday on the road without warning. No Battery or Check Engine lights appeared(both working) beforehand. Strangely saw ABS light before all this happened. Tach died just before car stopped. Took six month old Walmart battery back to store for test and charge. Battery tested sat and was recharged. Reinstalled in car and measured 12.6 volts engine off at terminals. Started car and measured 12.3 volts at battery terminals. I'm used to seeing over 14 volts. Still no battery light. Jumped in and drove car home. Even though there was no CEL on, I ran a scan anyway which showed zero codes. The car is super clean with around 80k miles and has been garage kept since new. I checked all connections topside and then got underneath and all connections seem tight with no corrosion. Belt and tensioner seem fine. Everything seems to point to alternator going south which looks like a real PITA to replace, but doable. Folks, I'm just an amateur here so would like to know if there is anything else to check before I pull the alternator out. Am concerned that battery light didn't come on prior to this happening and not coming on now with battery obviously not charging. Thanks in advance for any ideas.
