Engines without interface
3.1.3 Engines without interface
Not every engine has a digital interface and thus the
wiring becomes more elaborate:
Disconnect any existing wires within the engine and
any connection to the chassis. Both motor contacts
must be isolated, make sure there isn’t any connection
to the chassis, the wheels or the pantographs. This
may easily be overlooked particularly in Fleischmann®
models!
After installing the decoder please check all
connections with an Ohmmeter and look out
for any short circuits between motor- and current
pick-ups.
How to proceed depends on how the headlights and
other functions are wired in the engine:
a) If headlights and functions are isolated from the
engine chassis (free of any voltage) proceed as per
figure 2.
