1. Tilt and trim module
The tilt and trim switch provides B+ input to
green/white or blue/white wire of the TNT module.
Operation
The relay activates when B+ input from the switch
is supplied to terminal 86 of the internal relays.
Terminal 87a connects to ground (B–).
Terminal 87 connects to B+.
Terminal 30 connects TNT motor.
Terminals 87a and 30 are connected when relay is
not activated. This supplies ground (B–) connec-
tion to TNT motor.
Terminals 87 and 30 are normally open. B+ is
applied to terminal 30 when relay is activated.
This supplies ground B+ connection to TNT motor.
Refer to Tilt and Trim Module Diagram.
