Troubleshooting can be difficult. The Troubleshooting Index gives a list of possible problems. To make a repair to a problem, make reference to the cause and correction on the pages that follow.This list of problems, causes, and corrections will only give an indication of where a possible problem can be, and what repairs are needed. Normally, more or other repair work is needed beyond the recommendations in the list.Remember that a problem is not normally caused only by one part, but by the relation of one part with other parts. This list is only a guide and can not give all possible problems and corrections. The service personnel must find the problem and its source, then make the necessary repairs.1.

Problem 1: Contactor Switch For Water Temperature Does Not Activate Shutoff Solenoid Probable Cause:1. Wrong Connections Connect battery to Common Terminal (C) and shutoff solenoid to Normally Open (NO) connections. Check connections to other components or make installation of new wiring.2. Failure Of Shutoff Solenoid Check the shutoff solenoid.3. Low Water Level In Cooling System Fill the cooling system.4. Wrong Setting Of Switch Make a test of temperature setting and if necessary install new contactor switch with correct setting. See specifications. Problem 2: Contactor Switch For Water Temperature Activates Shutoff Solenoid At Wrong Temperature Probable Cause:1. Wrong Setting Of Switch Make a test of temperature setting and if necessary install new contactor switch with correct setting. See specifications. Problem 3: Contactor Switch For Oil Pressure Fails To Activates Shutoff Solenoid Probable Cause:1. Wrong Connections Check connections, wiring and correct where necessary.2. Wrong Setting Of Switch Test contactor
