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.

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.
