Battery light
2005 Mazda 3, 2.3 litre auto.
My battery light has been on quite a bit in the past week and a voltage measurement on the battery when the engine is off and when running confirms a no charge condition when the light is on and the odd time it's off, it is charging. It does go off at times while driving but is mainly on. Battery checks good, cables, connections are good so I've picked up an alternator and will install that in the next day or so. Before I install it I'm going to take resistance measurements between all terminals which may or may not help someone diagnose a faulty alternator but any info is good to have. I'm hoping it's the alternator because if it's not, I'm looking at the pcm or worse. Anyone else have any ideas, experiences, common issues with the charging system?
