500 RPM
all this while im using this method, stepping on throttle during idle in traffic, voltage getting low until 12.4 v @ 800 rpm. so tekan till 1.2k ish rpm to get 13.8v..hahaStepping on the throttle is what i have been doing when the fan comes on, to keep the voltage high. The rational behind downsizing the pulley is to allow it to spin at faster rate at low RPM to generate high electricity at low rev range, i don't see how that will add more load to engine ?
Thanks,
Ken
alternator change once, the one come with halfcut kaput, and replace with another halfcut part, just recently found that evo3 uses 75A rated alternator. So swapped in perdana alternator 90A and solve everything. 130A RA alternator ada around 4xx...tempted to buy but not sure wiring can support that output..haha
