Electrical Problems

So can't seem to figure out my 04's light dimming issue
Has new this year, Dual-battery set up, Both batteries 1100CCA, 250A alt. 0/1 Wire upgrades on battery to chassis, chassis to engine, battery to engine, and cab to chassis.
So problem is whenever I use anything that draws large amounts of power (Windows/plow/Defrost) my headlights, in cab roof light, and dash lights all dim.
Thoughts on what the issue is?

Somewhere you may have a super high resistance on something. Start metering your ground returns. Seen a bad ground on a firewall of a Ranger cause all sorts of havoc on a electrical system. Are you at idle when the voltage drop is happening? Does it still happen at highway speed?

Use the search function on the gray line above.
Search : Charging, Low Power, Lights Dim, Duel Batteries -- etc. There is hours of reading there. It's an issue beat to death every year. When you say dim is it really dim or just dim a little? Any change from what you had before? Any high amp drain will drop the voltage a little and cause dimming. An alternator only puts out 1/3 of it's rated amps at idle.

Sorry, forgot to respond
Checked all the wires I installed for resistance and came up with a 0 on every one.
So I took the extra 18ft. of 2ga I had laying around and added some more grounds, seemed to clear up the issue.
Guess you never can have to many grounds.
