6.7.3. Colour Coding by Märklin®
Märklin® uses a different colour coding system compared to the
DCC colours. Please refer to fig. 8 for more information.

6.7.4. Motor and Track Connections

Firstly, please cut all wires installed in the locomotive. Take special
care to remove any connections to the chassis (ground): the motor
leads must be positively potential-free, in other words they may
not have any contact to the chassis or body or the wheels and
wheel contacts.
It is particularly easy to overlook such connections in Fleis-
chmann® locomotives.
Make notes of which motor lead connects the motor with the
right and the left wheel contact.
This avoids mistakes and assures that your locomotive runs in the
right direction.
Please check all connections with an Ohmmeter. Search for
short circuits, particularly between the motor leads and the
wheel contacts.

Figure 8: Colour coding by Märklin® in contrast to the DCC wiring code
• Connect the red wire to the right rail pickup or the centre pick up
in AC models.
• Connect the black wire to the left rail pickup or the chassis in AC
models.
• Connect the orange wire with the motor terminal, which originally
lead to the right wheel pick up (centre pick up in AC models).
• The grey wire goes to the terminal, which originally connected to
the left rail (chassis for AC models).

6.7.4.1. Connecting DC and Coreless Motors

You may use all DC motors commonly used for model trains pro-
vided they do not exceed the current limit of the decoder.
In some cases with the 5-pole High Performance Drive by Märk-
lin®, you may find three anti-interference capacitors.
The two capacitors connected directly to the motor leads and the
motor housing MUST be removed (also refer to Fig. 9 on the fol-
lowing page).
