Introduction: Charging Problem in Electronic Scale (500kg)
this is a scale having charging problem
Step 1:
First Open the box
disconnect the all jacks
Step 2: Checking the Circuit
check the secondary winding of transformer
there is no reading against secondary winding of transformer
but It have reading of primary winding
and in circuit have a bad capacitor (1000uf/25v)
Step 3: Changing the Capacitor
Step 4: Replacing the Transformer
it have 10v transformer
I replaced with 9v transformer
after this I connect the circuit
Step 5: Finished
after connecting the circuit
I connect it to the AC
now it show 7.66 volts on battery terminal
after connecting the battery is now on and charging the battery
