SPECIFIC TEST PROCEDURE FOR FUEL GAUGE USED BY CATALINA YACHTS

(Other systems may use a different procedure.)

There are FOUR components in the fuel gauge system on Catalina Yachts and therefore four possible sources of fuel gauge problems.

This article will explain the testing procedure for this system.

 

 

 

1 - The FUEL GAUGE in the engine control panel may be defective.

TEST PROCEDURE :

2 - The PINK SENDER WIRE may be DISCONNECTED from the sending unit at the tank or SHORTED TO GROUND.

TEST PROCEDURE:

3 - The BLACK GROUND WIRE may be DISCONNECTED from the sending unit at the tank or NOT GROUNDED at the other end.

TEST PROCEDURE:

4 - The SENDING UNIT in the tank may be defective or the wrong unit may have been installed.

TEST PROCEDURE:

STEWART WARNER, 240 TO 33 OHMS RESISTANCE

There are several other resistance specifications available but those sending units WILL NOT WORK in this application.
