Iraggi Alternator Posted May 7, 2012 Report Share Posted May 7, 2012 Sounds like what he said... when you put it in drive and sit there your rpms are too low for the alt to turn on... If it just started doing this but didnt before... One of two things.. Either your rectifier is going out or you have some batteries pulling more current than they used to before. Like they are going bad or need to be charged overnite. What could cause the rectifier to go out? Especially this fast, it's only been about a year and the car gets used like 1 a month if that. I already tried having the batts on a charger over night, I'll try it again though. Usually bad or weak batteries... or very poor connections. Check your battery resting voltage after you charge them overnite. Check them every 3 hours or so and see how they hold the charge. Quote Link to comment Share on other sites More sharing options...

Iraggi Alternator Posted May 8, 2012 Report Share Posted May 8, 2012 No. thats not enough current to get them charged. I would do between 5-10 amps per battery..overnite Quote Link to comment Share on other sites More sharing options...
Berto Posted May 9, 2012 Author Report Share Posted May 9, 2012 Seems like there was an issue with one of the rear batts, cuz now that I removed all 3 rear batts it doesn't do it anymore. I'm still gonna charge the 3 batts one by one and see how that goes. Quote TEAM FLEX ISSUES Car: 1985 Oldsmobile Delta 88 Royal 24" Rims HU: 7" Carputer, Planet Audio EQ, iPhone.

Iraggi Alternator Posted May 9, 2012 Report Share Posted May 9, 2012 Each batt will pull between 10 and 50 amps of charging current depending on good they are and if they are fully charged or not. If your alt makes lets say 75 amps at idle and you have 4 batteries... your voltage may be in the 12's with the car running at idle. You may or may not have a problem with the batteries.. do like you said and charge them all and have them load tested to make sure. If all else fails get an alt that has better output at idle.

falcons03079313 Posted May 9, 2012 Report Share Posted May 9, 2012 I had that problem too. Like everyone said adjust the rpm's and you'll be good Quote Link to comment Share on other sites More sharing options...

I would hope it does more than that at idle. It's a 250a alt. Never got the idle output though. But yeah I'm still gonna charge and check the battery.

Like everyone said adjust the rpm's and you'll be good I'm gonna see if the batteries were the problem and if it's not this will be my next step.

Iraggi Alternator Posted May 10, 2012 Report Share Posted May 10, 2012 Depends on the case style. If its a small case then output at idle will be very low. If its a large case and it has low output at idle than its not a very good design. Each batt will pull between 10 and 50 amps of charging current depending on good they are and if they are fully charged or not. If your alt makes lets say 75 amps at idle and you have 4 batteries... your voltage may be in the 12's with the car running at idle.

Berto Posted May 10, 2012 Author Report Share Posted May 10, 2012 Would AutoZone's battery test be good enough to see if the batts are good?
