baron_of_bass Posted November 8, 2016 Report Share Posted November 8, 2016 I was having the same issues. I ended up trading my core for a autozone battery and stopping having issues, hmmmm weird. Good luck big Quote Team Bass-Hz Link to comment Share on other sites More sharing options...
ToNasty Posted November 8, 2016 Report Share Posted November 8, 2016 It's fine. My pcm controlled vehicles run at 12.4 to 12.8 all dsy. Turn your lights on and your charging voltage will go up to mid 14 1 Quote ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
bsneon98 Posted November 8, 2016 Report Share Posted November 8, 2016 probably a pcm controlled alt.This is why I absolutely despise new cars. too many damn computers 1 Quote Build Log: http://www.stevemeadedesigns.com/board/topic/152954-1998-plymouth-neon-updates/ Link to comment Share on other sites More sharing options...
Keith77 Posted November 8, 2016 Report Share Posted November 8, 2016 The PCM controlled. It will let the voltage get into the 11's before it will kick on the alt at times. Quote Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born. My penis is bigger than your penis I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle.

kickass audio Posted November 8, 2016 Report Share Posted November 8, 2016 like everyone is saying it's probably your PCM doing it. If your car has it did you make sure that any power wire you ran between the alternator and battery was inserted in the battery current sensor? If you have another wire running from the alt to battery and it isn't in the sensor (if your car has one) it can cause erratic voltages since it can't sense what amperage is being drawn to kick the alternator on. If your car doesn't have an current sensor on the OEM battery leads then your PCM is controlling the voltage and the only workaround is to either try and see if turning on your headlights manually will trick the alternator to be forced into a 14v output otherwise you can get something like an Mechman voltage boost module or even the xs power VCM but the problem with that is it would get your battery light to come on in the dash as the car won't sense the alternator to see what it is working at and think it is dead when it is actually working.

bigp88 Posted December 20, 2016 Report Share Posted December 20, 2016 pcm does that to save gas mileage or some shit from the factoryI had mine unplugged for a long time but here lately it's doing better plugged in Quote Link to comment Share on other sites More sharing options...
