Figure 6.12 Connections To Vehicle DC Supply
To connect the diode, push the male connector on the diode assembly into the
female connector on the positive (red) lead of the power cable. If the fuse
assembly is already installed, connect the diode assembly to the fuse assembly
as described in the previous sentence. Connect the red wire from the diode
assembly to a fused power source on the vehicle.
It is recommended that all connections be secured with electrical tape or heat
shrink to prevent contaminants from degrading the connection.

Note: When installing the 8515 on vehicles operating on 24 Volts and above, the
diode assembly (supplied with the extension power cable 13985) should be
used to reduce the AC ripple produced by the SCR traction motor controller
on the vehicle.
