A friend has s problem with his 05 Rubicon.
Some weeks ago he installed a flex a lite e fan.
But everytime the e fan turns on at idle speed the voltage goes down from 14.4 to about 12.5 V.
Is there another alternator available that puts out more A at idle?
Perhaps from another Dodge or Chrysler?
A mean Green is a bit to expensive...
He has the stock 136 A alternator.
Thanks for your help.
