Has anyone upgraded to a high amp alternator? Im only running a few things and you can see lights dimming under heavy draw. i upgraded to an Optima red top which made a noticeable difference but its still not enough. I have light bar on the way. i dont wanna just slap on a big alternator and fry anything... any info would be appreciated.

 

I would get in touch with Ohio Generator and have them custom make you a H.O.Alty .. had that done for my old Avalanche and their pricing wasn't bad at all ..

 

Here is what I've found, though I am not at home it makes it difficult, but this is what I researched.

hm-did you replace the factory alternator wire and power/ground wire when you added the red top? upgrading that will make a difference. i have experience with the wrangler products as well-they are good. one easy option is to check with your local generator/alternator shop. we have one nearby and they have rebuilt some customers alternators in the past with huge systems to increase the amperage-thats a nice option since you know your alternator will bolt right up without brackets or mods.

 

Thanks for the info. I am gonna get one made from Ohio Gen. and also have the wiring upgraded by themthey seem to have GM pretty well covered... now Im thinkin about upgrading everything to HID . might as well. I appreciate the info From all.

 

Great info for powering large audio systems....keep up the good posts
