MOTOR RELAY (J&J# 2-70-0033)
General Relay Information.........................................3-21
Testing the Relay .......................................................3-22
Relay - Removal & Replacement ...............................3-23
The relay (J&J# 2-70-0033) is a simple 24VDC marine-style unit. It consists of a spring-loaded plunger that is moved via
an electromagnet. This magnet is created when the control circuit (two small contact posts) is energized via the micro/
solid state switch circuit. When the control circuit is energized, the plunger moves up and a large contact washer
makes the connection between the input and output (large) terminals, thus allowing high amperage current to flow to
the motor.
To verify that the relay is functioning properly (without replacing it with a unit that is known to be so), perform the
following simple tests. Before beginning, first verify the voltage at the main power post of motor. The voltage should
match the battery voltage (same as voltmeter reading on back of boat).
