hey i have a 2005 ford 6.0 dually i have a 1200 wat amp 42 inch light bar touch deck a cs tuner for gauges and a few other little lights im running a 130 amp alternator right now but im pretty sure i need a bigger one what size should i go to ? i can get a good duel on a 185 amp one right now is that big enough ? im going to be adding another light bar to. i heard something about upgrading the wring for the alternator? and i also could get a dual alternator set up for a good price ? thanks guys

 

I have 220 amp from DC Power engineering in Cali. Designed for over 300 amp output and destined for longevity. Check them out if you want a great alternator instead of a modded stocker! And it looks cool too!

 

what did you do for the wiring ? and how many volts is it putting out? how long have you had it ?

thanks man

 

The stock unit is definitely too small for you.

DC Power alternators will charge at around 14 volts.

You can not change to a dual alternator setup without a PCM change.

Lots of sources on the internet about the size of wiring to use - depends on the amp load you have. I have a 270W alternator and went with 2/0 wiring - don't forget upgrading the ground wire also.

 

DC power included an adaptor. Plug and play. Just over one year, so far very happy! Mine is just 220 unit but all I need. I figured its destined, so less strain on it versus a modded stock unit pushing more than it was designed for. I'm expecting a great long term experience with this unit!

It's detuned, not destined, sry!

 

bismic1 do you leave the stock wiring it to just put a bigger one over the other one thats in there from stock ? and where do you upgrade your ground
