hehe..yea, i just want to make sure everything is problem free..but then, how many years could a cap become bad? sometimes bad cap could actually drain battery charge rite?
but when i turn my key to ACC-ON (engine not running), i went to check the voltage it became from 12.3V drop to 11.7V, i dunno if this is normal...however no problem start the engine lah, 1 fast crank can dy..
when u turn to ign on, some electrical are running...ur ecu, tcu, bcm, sensors and ignition coil, meter lights..etc....they draw currents. but when i turn my key to ACC-ON (engine not running), i went to check the voltage it became from 12.3V drop to 11.7V, i dunno if this is normal...however no problem start the engine lah, 1 fast crank can dy..
as long as ur battery is >12 when not in use, and >13.5 after start, ur system is still ok...
Added on October 31, 2011, 2:20 pmu need a multimeter with capacitance reading to know whether a cap is good or bad. :>
