Title: fluctuationg voltage
Post by: cwilson jr on March 04, 2008, 03:28:15 am

while driving the voltage randomly fluctuates from normal to right at the high end on the orange.  doesn't effect driveability other than at night i basically have no headlights.  i would assume this would be the alt, but the battery always stays charged.  this is on my 85.
