speedball1978 Posted July 6, 2010 Report Share Posted July 6, 2010 whats a good voltage reading at idle before the system is on and after it has played...trying to get a good general idea if my charging system is in good standing, found out i can't get a high output alt for my car, there's not one made for it yet at this time Quote Link to comment Share on other sites More sharing options...

killallblue Posted July 6, 2010 Report Share Posted July 6, 2010 That's decent but I think they make a alt for that what motor is in that Quote Link to comment Share on other sites More sharing options...
chapo123 Posted July 6, 2010 Report Share Posted July 6, 2010 that voltage drop is not bad at all bro. if it was in the 12's then i would start to worry Quote Steve I don't know why but everytime I see your new paint I want a Dr. Pepper...... is this normal? heres an analogy for you. running a high power stereo without a fuse is like having unprotected sex with that hot chick at the bar with the sketchy sexual history. Sure you may be fine and nothing happens but that one time something does happen you're fucked. i dont want woofer broke like bass sound clip clip and voice coil overheat 2 sa12s, saz1500 build log http://www.stevemeadedesigns.com/board/topic/91183-chapo123s-sundown-build-log/page__gopid__1250604entry1250604 Link to comment Share on other sites More sharing options...

Noob_On_Droid Posted July 6, 2010 Report Share Posted July 6, 2010 (edited) That's a good size alt for a four Banger! A charged battery should sit approx 12.8v +/-.2v depending on battery and charging condition. Car on 14.4v is the standard. With your system playing anything 13 or above is fine for just driving around beating. Lastly, don't trust your epic BS take a DMM and get a good reading at the amp to know exactly what it is seeing.

finkster Posted July 6, 2010 Report Share Posted July 6, 2010 agreed. Everything above 13 means your alt is still working. Quote DAT 4125------>RE XXX comps active Eclipse cd7000 I serve drunks for a living Link to comment Share on other sites More sharing options...
speedball1978 Posted July 6, 2010 Author Report Share Posted July 6, 2010 agreed. Everything above 13 means your alt is still working. yea i've already checked with a dmm, the epic is pretty close to what the dmm reads... well in that case if i'm reading above 13v then i'm good, thanks guys for your input, i was mostly concerned with the voltage drop, i haven't done the big 3 yet.. don't know if i really wanna mess with doing the big 3, specially a 4 banger , freakin motor cramped in sideways, but oh well i'll deal with it later.
