Electrical Circuit Tests; Relay Testing; Trim And Tilt Motor Current Draw Tests - BRP EVINRUDE E-TEC 115 HP 2011 Service Manual

Remove the manual release valve. Install pres-
sure gauge and adapter "B" to check problems in
the DOWN circuit. Cycle the unit down and up
several times to purge air. With all rods fully
extended, run the unit down momentarily to
reduce pressure. Check fluid level again, and add
fluid if necessary. Remember that all rods must be
completely extended to check fluid level.
Starting with the tilt cylinder fully extended, run the
unit DOWN.
•
The gauge should show 0 to 200 psi (0 to 1379
kPa) as the tilt cylinder is retracting.
•
The gauge should show approximately 800 psi
(5516 kPa) as the unit stalls.
•
Release the switch and watch for a pressure
drop. The stall pressure reading must not drop
more than 200 psi (1379 kPa) after motor stops.
If results vary from the above limits, there is a
problem in the DOWN circuit. Refer to MODES
OF OPERATION (Three Piston System) on
p. 329 for circuit description.
CAUTION
After tests are complete, run the unit up,
then down momentarily. Cycle the unit
down and up several times to purge air.
With all rods fully extended, run the unit
down momentarily to reduce pressure.
Check fluid level again and add fluid, if necessary.

Relay Testing

When the trim-UP button is pressed, the UP relay
is energized and connects the blue trim motor wire
to the battery positive (+) terminal. The green trim
motor wire remains grounded. When the button is
released, the blue trim motor wire returns to a
grounded position.
When the trim-DOWN button is pressed, the
DOWN relay is energized and connects the green
trim motor wire to the battery positive (+) terminal.
The blue motor wire remains grounded. When the
button is released, the green trim motor wire
returns to a grounded position.
Refer to TILT/TRIM RELAY TEST on p. 104 for
relay testing procedure.
Trim and Tilt Motor Current Draw
Tests
Careful analysis of the electric motor's current
draw and trim/tilt unit operating speed aids evalu-
ation of the electric motor and certain mechanical
components.
Use a battery rated at 360 CCA (50 Ah) or higher
that is in good condition and fully charged to per-
form this test.
