UNA_06SS Posted May 30, 2018 Report Share Posted May 30, 2018 Okay so I currently have on my ISS a DR44G Alternator that is supposed to produce 145Amp. Not sure if anyone has had this issue, but sometimes when I'm driving I see the voltage drop to around 12v from the usual 14v. It doesn't happen all the time, but I'm wondering if the Alternator is going bad? When I purchased the truck 2 years ago, it came with it. Haven't done any modifications, don't have a sound system other than a Pioneer Double Din Stereo. Has anyone had this issue with their DR44G Alternator? Should I just replace it or would this be normal? Thanks! Quote Link to comment Share on other sites More sharing options...
EXGM Posted May 31, 2018 Report Share Posted May 31, 2018 Its normal. The PCM controls the alternator output once battery is charged it backs output down......... Quote Link to comment Share on other sites More sharing options...
UNA_06SS Posted May 31, 2018 Author Report Share Posted May 31, 2018 okay so I guess I don't need to replace it. I was going to do that later on this month. Thanks! Quote Link to comment Share on other sites More sharing options...
EXGM Posted May 31, 2018 Report Share Posted May 31, 2018 No..... mine with a stock alternator does the same. Totally normal. Its done in the name of fuel economy. Less drag on engine saves petro..... Quote Link to comment Share on other sites More sharing options...

QuickStyle Posted May 31, 2018 Report Share Posted May 31, 2018 when i did my dual electric fan swap, i swapped to the 145amp alternator and the 8 gauge charging wire was getting so hot it would burn my hand and would never go past 13 volts. swapped it out for a 4 gauge and now its only warm to the touch and runs around 14.4 volts.

UNA_06SS Posted June 1, 2018 Author Report Share Posted June 1, 2018 So these trucks never came stock with a dual electric fan? Quote Link to comment Share on other sites More sharing options...
someotherguy Posted June 1, 2018 Report Share Posted June 1, 2018 So these trucks never came stock with a dual electric fan? My '06 Intimidator SS has dual fans, OEM. I don't see any RPO codes in my breakdown that indicate that it's a special equipment option. I'm about 99% sure my wife's '06 SS also has them but it's not here for me to look at right now.
