Fitting the Battery Bracket

Steps 1-2

Retrieve your framework from the previous issue and fit the Battery Box Bracket into the bottom of the framework, as shown. Make sure the wires for the Main Switch and Charging Socket are out of the way:

Steps 3-4

Ensure the four ‘inner’ holes of the Battery Box Bracket fit onto the matching pins of the two Bottom Plates, as shown:

Steps 4-5

Secure the Battery Box Bracket into place with four (4) 2.5×4 mm silver screws.

There are two screws on each side, as shown:

Fitting the Circuit Board

Steps 1-2

Fit the Sensor Control Board (received back in Issue 52 and frequently used for testing thus far) onto the two pins of the Circuit Board Base, as shown:

Steps 3-5

Align the Circuit Board Cover over the base, aligning the socket holes to the board below, and press it into place:

Step 5

Secure the cover to the base with four (4) 2.3×6 mm black screws:

Step 6

Align the two pins on this case assembly with the matching holes in the Circuit Board Bracket, as shown:

Step 7

Secure this bracket into place with two (2) 2.3×6 mm black screws:

Steps 8-9

Fit this entire assembly down inside the framework structure, aligning it as shown:

Make sure these two small tabs are resting inside the ring, as shown:
