Been nearly a week since the new Alternator and the Mrs emailed me a photo today of the engine management light on again?! Not going to get home until tomorrow now to check it out but after fitting the replacement alternator I was getting a healthy 14v across the battery with a Multimeter. Battery fitted is a 100AH battery now YUASA so not a cheap one but I'm not ruling it out until I get home, previous battery was a 97AH but I can't see the extra 3AH being an issue right? Frustrating not having the OBD kit to plugin and I refuse to pay for a garage to charge me for 'diagnostics' as I think its a rip off. Wifes work sell OBD readers but the last one I plugged in wasnt of the correct variant so it was no help. Any pointers to begin fault finding this one much appreciated.
