Ok my problem is this :
I have a 1994 Honda civic cx in which i swapped in a d16y8 . Ever since i have swapped engines when the car is running and i turn on the headlights the lights dimm. The radio and every thing continues to work fine but my cluster and all surrounding lights dimm with no commonality to reving high being at idle or any thing. I have checked all grounds. I am pretty sure the battery is good. the car seems like it should have a good alternator(not 100%) , but it keeps power just fine. Does any one else or has any one else experienced this .
On a side not i removed ac and nothing is plugged in if that matters at all though i would tend to think not .

any input would be appreciated

serach was used nothing came up. ky used were dimming lights dimm electric etc.
