swapped in a new d16y8 into my 00 si (canadian).....motor runs fine, idles a bit high but runs good, problem is the tach and speedo jump all over the place, the lights flicker on and off on there own as well....like they will dim then get brighter, then dim then get brighter....the car runs normal when started until i rev it then the problems with the lights dimming etc starts. took the car around the block today and noticed my stereo shut off and would come on then shut off again, the lights would stop dimming for a bit then dim again and the tach would start going crazy.......brought the car home and it wouldnt start.........no battery light came on or anything.....any ideas?

 

Could be possessed...


Nah jk LOL

 

i checked my grounds, made sure my battery terminals were tight....its weird the lights are fine etc until i rev it and then they start to flicker, and now my deck etc turns right off and my interior lights an headlights dim right out.....

 

did you check the battery and alternator output?

 

did you get the grounds in the fuse box too?

 

checked the fusebox grounds as well

 

im gonna grab a new alt today and put it in and see what happens........soon as i take the negative off the battery with the car running it died.

 

have any good news yet?
