Volvo cold start after 6 years
My peeps at The forum forgive me for my absence. I come to you my friends with a serious charging issue. Misty was cruising along last week and all of a sudden the power started to dwindle and I got to my destination and went to turn the car on afterwards and it would not start. The first diagnosis called for an alternator so I replaced the alternator then the alternator was not charging the battery and that's still is the problem. I have a brand new alternator and a brand new battery and she will start right up but the alternator is not charging the battery and I've had a mobile mechanic look at it today and we can't get to the bottom of it. There was a severed wire between the battery and the starter cell solenoid which has been repaired but we can't figure out what's wrong with Misty. Please I beg of you my peeps, my tribe help me.
firstly don't think the wire from the battery + side to the starter would be the culprit. look elsewhere. the ones going underneath the radiator maybe...
hope you kept the old alternator.. just sayin..

does the dashboard 'batt' light come on when you turn on the ignition key, and go out when you start the engine ?
that light is a crucial part of the charging circuit, it provides the D+ 'bootstrap' current the alternator needs to start making juice.
the circuit goes from the ignition key to the light to the alternator D+ lead (skinny red(?) wire).
the other thing I've seen fail is the alternator GROUND wire going bad. start the engine, take a digital volt meter set for DC Volts, put one probe on the metal body of the alternator, and the other probe on the battery - terminal, if you read more than a few 10ths of a volt, the alternator ground isn't good. check from the engine block ground to battery -, if thats near zero, check from alternator body to engine block ground.... which ever one shows the bulk of the volts is where the ground isn't working.
