I recently bought a grid power supply, this is made by CAL DC for Grid, input
is 110-220 volt, output 16VDC @4 A, I would like to modify this as a battery 
charger & want to set the voltage at 13.2 V, any info on which resistor to ad
just is appreciated, It uses unitrode 3842 type IC, i tried adjusting res on 
pin 2 of 3842 but no luck
