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
