Step 9: Wiring the Relays For Motor A

Step 2: Wiring the relays for Motor A

You should have 8 relays and 4 dual sockets. Put each relay in its designated socket.

The following steps are only for two dual sockets ( four relays). The other two remaining dual sockets will get a different wiring which will be detailed in step number three.

By the way whenever I say to connect the wires , I mean to solder them together. Also, the wheelchair motors should have four wires coming out. There are two thick ones and two skinny ones. Leave the skinny ones alone for now. The thick ones should also be different colors, usually blue and red. If its different colors then just know that I refer to one of the wires as the blue wire and the other one as the red wire.

You can either follow the steps below or just read this schematic and follow it. Make sure you follow the shematic by color code.
Schematic

A. First Dual Socket:

1. One of the relays in the dual socket

Here is the color code key for the wires for the one of the relays on the socket , do this for only ONE of the relays:

BLUE- Connect to power( the positive ) of the motor's batteries. This is the motor's battery's , not the batteries for the relays.

BLACK- Connect to the ground(negative) of the relay's battery

YELLOW- Connect to the blue wire of the motor

WHITE- Leave alone for now

RED - Not used in this project so you could just rip it out or whatever

2. The other relay in the dual socket

Now for the OTHER relay thats in the same dual socket as the other one we just did:

BLUE- Connect to ground( the negative) of the motor's batteries. This is the motor's battery's , not the batteries for the relays.

BLACK- Connect to the ground(negative) of the relay's battery

YELLOW- Connect to the red wire of the same motor used above

WHITE- Connect to the white wire of the other relay in the same dual socket

RED - Not used in this project so you could just rip it out or whatever

Now that we are done with that dual socket , so set it aside. Pickup the second dual socket.

B. Second Dual Socket:

1. One of the relays in the dual socket

Here is the color code key for the wires for the one of the relays on the socket , do this for only ONE of the relays:

BLUE- Connect to power( the positive ) of the motor's batteries. This is the motor's battery's , not the batteries for the relays.

BLACK- Connect to the ground(negative) of the relay's battery

YELLOW- Connect to the red wire of the motor

WHITE- Leave alone for now

RED - Not used in this project so you could just rip it out or whatever

2. The other relay in the dual socket

Now for the OTHER relay thats in the same dual socket as the other one we just did:

BLUE- Connect to ground( the negative) of the motor's batteries. This is the motor's battery's , not the batteries for the relays.

BLACK- Connect to the ground(negative) of the relay's battery

YELLOW- Connect to the blue wire of the same motor used above

WHITE- Connect to the white wire of the other relay in the same dual socket

RED - Not used in this project so you could just rip it out or whatever
