3 Important information When testing this Dual Power Trim system, take special note of the following: 1. Control box harness connectors must be disconnected and key switch must be OFF. 2. Make certain that the jumper lead used between terminal 3 and 5 is used only when specified. The tests, listed following, are in a sequence according to probability of component failure. It is recommended, however, that all tests be performed even if a faulty component is detected early in the sequence. This precaution will guard against repeat failure if there is more than one failed component. Testing Dual Power Trim System Dual Trim Control Panel Wiring Diagram a - Relay No. 1 b - Relay No. 2 c - Diode Module d - Terminal Block e - Control Panel Relay Test Testing Relay No. 1 a. Test for 12 volts at terminal 2, using only terminal 4 as a ground. Voltage Indicated: proceed to b. No Voltage Indicated: replace relay. b. Connect a jumper wire between terminals 3 and 5. Test for 12 volts at terminal 2, using only terminal 4 as a ground. No Voltage Indicated: relay ok. Voltage Indicated: replace relay. 2. Testing Relay No. 2 a. Test for continuity between terminals 13 and 9. Continuity Indicated: proceed to b. No Continuity Indicated: replace relay. b. Connect a jumper wire between terminals 3 and 5. Test for continuity between terminals 13 and 9. No Continuity Indicated: relay ok. Continuity Indicated: replace relay. Diode Module Test Perform the following diode tests using an ohmmeter set on Rx1 scale. When testing diodes, take 2 readings. Note first reading; then, reverse meter leads again noting reading. If diode is good, meter should indicate a high or infinite resistance (no meter movement) when connected one way and a low reading (below 60 ohms) when connected the other way. If both readings are high or infinite, diode is open. Replace diode module. If both readings are low, diode is shorted. Replace diode module. Diode No. 1 Connect a jumper wire between terminals 3 and 5. Test diode between terminals 9 and 10. Diode No. 2 Connect a jumper between terminals 3 and 5. Test diode between terminals 10 and 13.! CAUTION Before proceeding with further diode testing, remove fuse from red/purple harness lead so that it will not be possible to short either control box or VOA meter. Diode No. 3 Test diode between terminals 6 and 12. Diode No. 4 Test diode between terminals 12 and 7. Diode No. 5 Test diode between terminals 8 and 11. Diode No. 6 Test diode between terminals 14 and 15. Diode No. 7 Test diode between terminals 8 and 5. Diode No. 8 Test diode between terminals 5 and 15. DUAL POWER TRIM CONTROL - 5E-1

4 Trailer Switch Test! CAUTION Remove fuse from red/purple harness lead before proceeding with test. 1. Set ohmmeter on Rx1 scale. 2. Push down on TRAILER switch and check for continuity between terminals 10 and 3. Continuity Indicated: proceed to step Push up on TRAILER switch and check for continuity between terminals 2 and 12. Continuity Indicated: switch ok. Dual Power Trim System Component Repair Important Information Use care when removing and installing components. Do not force or pull wiring during replacement. Use care to prevent wiring from stretching, pinching or chafing. Coat all terminal connections with Liquid Neoprene. Relay Replacement 1. Remove control box cover. Starboard Trim Switch Test 1. Set ohmmeter on Rx1 scale. 2. Push down on STBD TRIM switch and check for continuity between terminals 1 and 9. Continuity Indicated: proceed to step Push up on STBD TRIM switch and check for continuity between terminals 11 and 6. Continuity Indicated: switch ok. Port Trim Switch Test 1. Set ohmmeter on Rx1 scale. 2. Push down on PORT TRIM switch and check for continuity between terminals 2 and 13. Continuity Indicated: proceed to step Push up on PORT TRIM switch and check for continuity between terminals 14 and 7. Continuity Indicated: switch ok. a - Screws b - Cover 2.
