purplesyrup Posted April 6, 2013 Report Posted April 6, 2013 Check out what the voltage does on this thing. I will also add that the resting voltage is staying high after a charge until i run something on it for a about 10 minutes, then it goes down to about 13.5 on my meter, or about 13v true resting voltage. My meter has prooven to be 1/2 volt off. Also, it was funny when i uploaded this because youtube slapped a copyright claim on it 1:21 is where they claim to hear a song called "Day Or Night Muical composition" LOL I disputed it, my reply was "How the hell do you get that song out of a running vacuum? LOL
SnowDrifter Posted April 6, 2013 Report Posted April 6, 2013 The motor isn't working harder - quite the opposite actually. When plugging up the end, you are creating a vacuum then the motor just swirls around the air that's inside it. Swirling around the air takes less energy than actually moving it from A to B - hence why the motor's RPMs go up instead of down. I'm assuming you have the battery hooked up to a charger of some sort? ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444

I'm assuming you have the battery hooked up to a charger of some sort? no, it was not on a charger, it was sitting on the floor, jumper cables hooked up to that vaccum, but i see what you mean, that makes sense, it just sounds like its working harder. I was wondering if the battery somehow was compensating for a higher load some how lol, I was just confused
SnowDrifter Posted April 6, 2013 Report Posted April 6, 2013 Perhaps your multimeter is picking up some sort of AC ripple created by the vaccuum and that's why it starts to read high? ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444

purplesyrup Posted April 6, 2013 Author Report Posted April 6, 2013 Perhaps your multimeter is picking up some sort of AC ripple created by the vaccuum and that's why it starts to read high? Yea maybe, I also noticed that vacuum's wire got pretty hot. I was originally like hell, if this thing spikes 16 volts on a burp, WIN lol

knowledge Posted April 6, 2013 Report Posted April 6, 2013 the meter is pretty accurate, surprisingly. i was just testing something the other day with that same one, then did the same with a fluke it was 90% spot on. and im still waiting in a pm on them batteries fool REFF'SMy linkEBAYhttp://feedback.ebay...ck&myworld=trueI love car audio so much because I will never be done. I can never win, and I will never get it finished or perfect. It always has me coming back for more, I can never get my fill of it, but I get what I need.

I do have a clamp meter, LOL good Idea snow, I will retest and use the clamp this time after i get done changing my oil
