New Alternator. Electrical Problems?

[RensoreK]

I don't know if this is normal, but during low RPMs my headlights will dim temporarily while the RPMs increase, I have a 93 Accord LX Sedan and I know its alternator is 80A and the battery is getting a bit old (even though it has enough power). I am replacing the battery with an optima and a new alternator...

My Question is:

The new alternator outputs 135A, will this type of output damage any electronic s or electronic sensors? Everything is fused with the proper default fuse, and the reason for changing the battery and alternator is because of high drain audio and electronic equipment in the vehicle. If anyone can help me out I *do* appreciate it

135A won't damage anything. The electrical components will only draw what they need. I have a 140A alt and everything's fine.

Be warned though, the alt and battery might not fix your problem. I have a Yellowtop and installing the HO alt actually made things a little worse at idle. Some HO alts have lower voltages and current at idle than the stock alternator.

Upgrade your "big 3" wires with some hefty 4ga or 0ga wire and it should make a difference.
