bobonit Posted January 30, 2009 Report Share Posted January 30, 2009 Check to see if your belt is slipping. That could explain why the voltage goes down with more demand. Its harder to turn the pulley when the demand is higher. 97 Maxima SE Bunch of shit going in, check out the build Build Log Link to comment Share on other sites More sharing options...

One more time go andtake you car to a shop and tell them to put your idle above 800 rpm and trust me problem solve how many more times do i have to say it, read before you buy a product it tells you what to do with that product trust me that was the same thing even in a red light or stop sign when below 12v so good luck. what bat are you using.

AH.. sorry i have no idea what you are talking about buddy...i said in my original post that i have 3 yellow tops..i only know of one company making yellow tops...optima..maybe you should read the post before telling me to "read before i buying the product"..and the voltage is 13.2 driving down the road at higher RPMs not idle ..at idle it is like 13.0..it drops lower when i am bumping the system further more it was idling at 14.6 when i got it so adjusting the idle is not the problem..not trying to start stuff just trying to see if anybody else had this issue and what might have fixed it before i contact the builder..peace..
