Okay before i get jumped on and told to use the search ..
i did and it has helped but still at a bit of loss here ..
My tour has a new alt not a rebuild .. put in by the last ovner ,and the batt is in the trunk and its about a year old .
Any ways in high rpm the batt light comes on and my head lights get very bright ! then dim when the batt light goes off.
Also if i let my car sit for a length of time the batt will die .
now i have checked all the wires best i could .
im getting proper volts at idle and with car off ..
but i did notice that with the car off the volts drop ever so slowly .
comments ideas ?
thanks guys
