johnarias15 Posted January 15, 2013 Report Posted January 15, 2013 Hi, Recently got my VM-1 Voltmeter and noticed that the voltage is a little high. I do have subs but I can't get the voltage to go down with some hard-hitting bass. Is this the first sign of the battery dying. The battery and alternator I currently have are original parts. 2010 GMC Sierra.

CoritaAlterado Posted January 15, 2013 Report Posted January 15, 2013 It could possibly be the voltage regulator in your alternator.
Guest Posted January 15, 2013 Report Posted January 15, 2013 It could possibly be the voltage regulator in your alternator. i'm fairly sure that the alt is pcm controlled.

RCP Audio Posted January 15, 2013 Report Posted January 15, 2013 my guess is that there is a dial on the back that your turn? not to sure, but thats what alot of them have PSN: Rcp_soundz Good rule of thump is go by what fuse size is being used in these amps. The higher the more amperage it pulls, this is what I look at. I'll stick a 300 amp fuse in a potato and sell it to you for $2k. 1991 Mazda 323VERY small build thread here: http://www.stevemead...23-small-build/
LoudPursuit Posted January 15, 2013 Report Posted January 15, 2013 did you calibrate the VM-1? how do you calibrate the VM-1? Dont know if you can....I know with the stinger gauges they come with a little screw that helps you correct the voltage reading.

johnarias15 Posted January 15, 2013 Author Report Posted January 15, 2013 You don't have to calibrate the VM-1, since it's analog. 2010 GMC Sierra SLE Texas Edition Sky High 2/0 OFC Wiring 2 Digital Designs 1508's Supercharged Digital Designs Door Speakers Rockford Fosgate T1500-1bdcp Rockford Fosgate Prime 300x4 Rockford Fosgate 3Sixty.3 SMD VM-1 XS Power D3400

CoritaAlterado Posted January 15, 2013 Report Posted January 15, 2013 i'm fairly sure that the alt is pcm controlled. Never thought of that, I looked it up. He's correct, disregard what I said about the voltage regulator.
