How to Make an Electric Fence Charger How to Make an Electric Fence Charger
An electric fence charger will power up your electric fence to keep your animals where they should be and out of your vegetable garden. Build a simple housing shaped like a bird house but with a clear Plexiglas front to hold the circuit board.
Step 1 – Wire the Circuit Board
Use the 5 lengths of wire to fasten to the holes in circuit board for both of the coil terminals, ground wire, power wire and earth wire.
Step 2 – Cut the Lumber
Using the miter saw, cut the corner molding in half so you have 2-9 inch pieces with a 45-degree angle at the top end. From the 1x5 lumber, cut 2 pieces that are 8 3/4 inches with a 45-degree angle at the top end for the roof. From the same boards cut 2 pieces 10 1/4 inches long with a 45-degree angle on one end for the sides and one piece 7 1/2 inches long for the base. From the 3/4 inch plywood and cut a piece 4 inches by 7 1/4 inches for the back.
Step 3 – Assemble the Housing
Using flathead wood screws screw the sides into the base. Screw the back onto the sides. Put the roof pieces on and screw those into. Countersink the nails and weatherproof the joints with silicone.
Step 4- Drill the Holes
Drill one hole in each of the walls of the housing with the 1/4 inch bit. Drill 4 more holes in the back. Next paint a sealer on the housing.
Step 5 – Mount the Circuit Board
Screw the circuit board to the Plexiglas with the machine screws. Affix the toggle switch. Run the wires to the negative battery terminal and the earth terminals. Mount the coil with a machine screw. Run the wires through the back of the box. Cut the Plexiglas to fit in the open front of the housing. Put the molding on the front over the Plexiglas and screw it in.
Step 6 – Hook up the Battery
Put claw clips on the wires and affix the battery cables. Put the battery just off the ground underneath the post where the housing will be mounted. Clip on the positive and negative leads to the matching terminals of the battery.
Step 7 – Mount the Charger
Hammer a nail into the post and hang the charger. Make a grounding post by driving a steel rod into the ground near the box. Attach the earth terminal to the steel rod with insulated wire. Clip the high voltage lead to the fence.
This charger will power the fence that will keep your animals in, making you a good neighbor, and keep them out of your garden, making you a happy gardener.
