TILT/TRIM RELAY TEST
TILT/TRIM RELAY TEST
The tilt and trim (TNT) module contains the cir-
cuitry and relays required for power trim and tilt
operation.
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 considered “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 .
Test Procedure
Make sure red and black wires are connected to
12 V battery power supply.
Set voltmeter to 12 VDC scale. Connect test leads
to terminals “A” and “B” of TNT motor connector.
Use a wire jumper to alternately connect B+ to ter-
minals “1” and “2” of tilt and trim switch connector.
The meter must indicate battery voltage (12 V)
with B+ connected to either terminal.
