Lights dim when electrics used.

FYR where did you pick up your higher output alternator?

American made. New not refurbished. California based. 100% reputation report. warranty. Free expedited shipping.

Wow that's not a bad price! I may consider one of those with all the lights I have installed on the rack and elsewhere.

True!!.......Even with all the lights you do have on yours, you could even go to a 250 amp. I stayed with the 200 amp because I wasn't running as many lights as you have. It seems to be fine so far with no issues. Install was a breeze!!

All I did was get the part number of my stock alternator and made sure that the new one that I was going to get was a direct plug n play replacement with my part number. Their site provided this info and combined with the other factors that I listed earlier, I decided to get it.

Funny you mention that. I was making my rounds on Ebay looking for any deals and actually found a new 250amp alternator for $179. Definitely something I'm going to look into at some point.
