How to replace electrolytic capacitor?

Tip1: If a capacitor has long enough leads exposed on the front side of the board, you can cut the capacitor off leaving the old leads and solder the new capacitor to the old leads. This method is even faster. See the last picture for an example. Tip 2: You should replace all the electrolytic capacitors, not just the visibly bad ones.

How do you replace a capacitor?

Hold the new capacitor near the place where it is to go, bend the leads to fit, and then trim the excess wire from the end of each lead with the wire cutters. Leave enough length on the lead to allow for crimping it around the terminal. Again, be sure to avoid leaving stray bits of wire inside the chassis.

How do you replace capacitor jumpers?

Keep the jumpers short as possible and twisted together, it will reduce interference. Strip the ends of the jumpers, solder them to the old capacitor leads and to the new capacitor leads. Hot melt glue the new capacitor to the top of the board, the jumpers should remain twisted.

How do you discharge a capacitor?

Discharge Capacitor: To discharge any stored electrical energy, use an insulated screwdriver to short-circuit the terminals of the capacitor. This step reduces the risk of electric shock during handling. Disconnect Wires: Carefully disconnect the wires attached to the capacitor terminals.

How do I replace the capacitors on a Grundig Radio?

The simplest option is to disconnect the old can and leave it in place for appearance's sake, then wire the new capacitors out of sight underneath the chassis. The radio looks original from above and you will save a lot of time and effort. This method was used in the Grundig radio shown at the beginning of this article.

How do you put a capacitor on a circuit board?

For larger capacitors use thicker wire (lower gauge) or put multiple cat 5 strands in parallel to each lead. Find and mark all the capacitor leads on the back side of the circuit with + and -. Make jumpers that will go from the back side of the board to the front of the board where the new capacitor will be placed.
