MOTOR RELAY (J&J# 2-70-0033)
General Relay Information ................................................ 3-21
Testing the Relay................................................................. 3-22
Th e 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.
Th is 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 fl ow 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, fi rst verify the voltage at the main power post of motor. Th e voltage should match the battery voltage (same as voltmeter
reading on back of boat).
