Dashboard/Headlights dimming...
So after swapping the engine in my car I've noticed the infamous headlight/dash light dimming problem. Lights are fine at idle but will dim under power. I've read tons of other threads with the exact same problem but none with a solution.

This guy cut the altc wire and the dimming went away but that seems " rigged. "
I have a new battery that's been tested, tryed two different alternators, and checked all the major grounds.
Any input would be awesome
2000 civic ex w/ 97 spec b18c itr swap.

I cleaned and sanded the connections for the 3 major grounds on the engine and the ones in the fuse box under the hood.

The current alt was at 14.2v no load and 14.01v under load. I have the regular "small" civic battery. No electrical modifications at all, and no CEL's. The cel does work for sure.

Re: Dashboard/Headlights dimming...
So, to update the thread...
The car in question was totaled, (hit and run, some ******* in a minivan,) so I never got a chance to fix the dimming issue. This past week I swapped the engine/trans/harness to a new shell. I also bought a high output 140 amp alternator to go with.
Moral of the story, new car with same swap and same problem. This leads me to believe that my problem is somewhere in my harness. I plan on pulling the harness, stripping all the loom and inspecting it.
Meanwhile if anyone has any other ideas, let me know.
