As with all conversions remove the body retaining screws and lift off the body.
This circuit board has the resistors for the lights. As I would not be using the lights I removed the resistors and the wires.
Remove the four small screws to release the motor. The right hand mounting plate is fixed to the motor but the left hand mounting plate is free.
This small circuit board
carries the two contacts
that tranfer the power to the motor.
THEY MUST BE INSULATED.
I know this is not the best picture but at the bottom
- as you look at the picture - is in contact
with the metal frame.
As I had no intention of reverting to dc I removed
most of the two contacts and the covered the remainder
with insulating tape.
This is the motor showing the
two terminals.
Attach the orange and grey wires.
For this conversion I used a Digitrax DZ121 which
I had spare in my decoder box. To save space I
removed the function wires from the decoder.
With the small circuit board removed the contacts attached the bogies can be seen. These wipe on the on the metal H on the reverse of the small circuit board (see the picture below).
This is the reverse of the
small circuit board which
has the suppression components. I removed these
It goes without saying but clean up the H shaped
metal as this is where the power gets transferred
from the bogie pickups.
At the top edge of the
board it the pickup which touches the body frame
for power transfer. So connect the Red to H and
the Black to the body pickup, or vice versa.
To finish cut two notches in the large circuit board
to enable the wires freedom of movement.
Re assemble and test.
