hello i have an 06 zx3 with a five speed and a powerful system. i did the big 3 in this car and installed an optima red top. I installed a detroit reman h/o alternator and now when my car comes to an idle it stalls everytime i sent it back and they rebuilt it and put the smallest pulley they have on it and it does the same thing does anybody have an idea also when you turn the wheel all the way does anybody else get a clunking noise like it hits something
Thanks in advance

i'd check to see if anything is binding when you turn the wheel. jack the car up and turn the wheel. You could have a bad battery connection or ground. are you getting any error codes?

thank you i will check the steering saturday and there are no codes it almost seems like its being draged to a stall idle dips low plus it shows negative amp output i checked the grounds they are all good it ran with the old alternator but ive killed it 3 times now i am so mad at this thing ive ben fighting this for 3 months now i am thinking about selling the car if i cant solve this and keeping the stereo but i would rather solve this

The steering I wouldn't worry about. More than likely it's just the noise of hitting the steering stops, if they are still there (I broke mine off thinking they where something else).

Negative amperage? So wouldn't that mean that the alt may be spinning to fast at idle? Maybe you want to put a bigger pulley on and see the result.

Maybe the regulator is all screwy and took the battery out then, not really sure, can happen though and it can be more common if it's overcharging at higher RPM's.

I do have to mention this also. You mentioned you have a large stereo, but you're only running 1 battery. If that is the case I am finding the alternator as being overkill. It could be that the demand the stereo puts on that single battery and the reaction time for the alternator to up the amperage to the demand is sub par. Meaning that the battery is being heavily discharged before the alternator can kick it up, hence slowly killing the battery, and if it's a newer Optima ('04ish and newer) they have lost the great quality they once had and are now just a fancy name.

Also if this stereo is that large and the alternator is capable of keeping up, the power wire to the alternator should be up-sized. I wouldn't doubt if the fusible link is on its last leg and maybe causing a problem, it's the first 8" or so of the power wire from the alt to the battery.

i sized up the wire to 4 gauge and i havent even used my stereo in 2 weeks because of this problem so that aint it the car runs fine with the old alternator but i kill them left and right due to overworking them (thats what the guy who rebuilt mine said anyhow) o and now I have power steering problems think the pump is going i don't know if that gould be an effect of the H.O. alternator or not. also the car always starts right back up so i dont believe the battery is being drained man this is getting really annoying[chair] [?|]
