Bigger Alternator?

[scott_s]

Hi,

I notice when I have the car lights on, the laptop plugged in, the scanner going, the invertor starts to beep about low voltage when I am at idle. It really does not like it when the heated seats get turned on too. Of course I have the underdrive pulley on.

Would a bigger alternator help with this? How about a bigger pulley for the alternator?

Thanks
Scott S

A bigger alternator will help.
A bigger pulley will make things worse, it will cause the alternator to spin slower.

Get the Nippendenso 90 amp that is a direct bolt in replacement.

You can also raise the idle RPM slightly with the set screw in the TB.
