ScreamingSkulls Posted November 12, 2010 Report Share Posted November 12, 2010 So this is a 220 Amp High Output Alternator, new, installed in a 2005 Ford F150. My old alternator gave me a solid 14.3-14.4 on idle but due to new system being installed I needed a new alternator. I'm getting 13.3-13.6 at idle and sometime as low as 13.0 while driving. This is WITH the system turned off. Now I contacted the company at which time they suggested a smaller belt because of the smaller pulley. My old belt was only about 9 months old and was a goodyear gator so I ordered another belt 1 inch smaller (what a bitch to put on). Anyways, I haven't measured the amps, well I tried but had the wrong tool. I know amps and volts are different but I'm not feeling good about my choice. Can anyone give me their opinion on this situation? Link to comment Share on other sites More sharing options...

ScreamingSkulls Posted November 12, 2010 Author Report Share Posted November 12, 2010 Without throwing the name of the company out I'll try to contact them again. I'm one of those guys that don't like to trash a company until they get a chance to fix the issue HOWEVER I can say it's not from an ebay company. It came from a reputable provider, I think...lol. btw loganberry, My system is: Pioneer AVH-P4200DVD, RE SXX 12 in 2.45 Custom Port Box, Power Bass Components Front, Powerbass 5x8 rear, Powerbass ATM 900.1D Wired 1 ohm for sub, Powerbass XAX 4160FD for front and rear speakers, Stinger PRO 50F Digital Hybrid Capacitor all wired using KnuKonceptz KCA Kable 1/0 with the big 4 power/ground Pictures: http://www.xperties.net/photos/v/cars/f150/trucksystem/ Link to comment Share on other sites More sharing options...
AMI CUSTOMS Posted November 12, 2010 Report Share Posted November 12, 2010 What does the voltage do when you turn the system on? And you are sure your battery is "good"?

fr34kout Posted November 12, 2010 Report Share Posted November 12, 2010 Not all companies regulate their alts at 14.4, just saying. The real question is how is your voltage at full tilt? I'd take 13.6 idle and 13.2 full tilt over 15.0 idle and 12.9 full tilt any day. Link to comment Share on other sites More sharing options...
