Ever Since...

I installed my new alternator (200 amp from dbelectrical) I also did big 3. Since I installed it in my 2000 Lincoln LS I noticed when I rev my car to 1500-2000 rpm the lights brighten quite alot. after 2000 rpms they go back to normal. I always thought it was because the increase in amperage to my battery and intern my headlights in internal dials ( they do the same thing ) I have been driving a few months with it like this and no problems with failures. Its just that its almost so noticeble at night that i think someone is going to think i am signalling them to turn or something when at a 4 way stop. So I'm just wondering if i should bring it to canadian tire ( canadian ) to get my alt checked or battery ( its stock ) or if there is a small fix ( adding resister to headlight fuse or internal lights fuses ). Thanks!

I would have the alt diagnosed.

It could be making more juice at certain RPM's which would make me suspicious of the internal regulator.

more importantly the alt is probably putting out very low amperage at lower RPMs which isnt good.

I'm going to get it checked out tomorrow. At my local Canadian Tire lol
