does this come complete to plug & play- ie with brackets and connections and wires- Mine is TJ 2003, manual, 4.0L Gas and its right hand drive. Will I need to change the factory stock wiring? Thanks Gill Australia

it is advertised as a 200 amp alternator but the specs say its 140 amp What is the true ratings at idle and at speed please

Asked by Btty Blu from C-bus ohio on

Hi Btty Blue, This high output alternator from Mean Green puts out 140 amp at idle, however it has a built in reserve that kicks in when amp draw is increased (lights, winch, etc) to 200 amp for vehicles with electrical accessories. The original alternator does not have this ability, hope this helps and thanks for the inquiry.

Will this alternator work with the single standard battery? I have an 06 Rubicon Unlimited with a winch. I notice when at idle my lights dim down but when throttle is given they brighten back up. At idle what is the amp's on this alternator vs my stock unit?

Asked by Trailbuster from Easley SC on

Hi Trailbuster The High-Output Alternator will work on your Jeep, at idle the alternator puts out 100 amps. Thanks
