(Figure 1, Items 1 and 5) Replace damaged wires if applicable. If there are no damaged wires, continue to step 6.3. Step 6.3 Pressure Switch Failure Unplug Weather Pack connector to High Pressure Switch and check the two terminals in the connector for continuity. There should be no continuity. Switch T-Dolly to MANUAL mode. Fully retract drawbar. If motor will not run skip to step 6.4. While holding down the RETRACT switch and bottoming out the cylinder, check the High Pressure Switch for continuity between the two terminals on Weather Pack connector. There should be continuity while the cylinder is bottoming out. If this is the case, continue to step 6.4. If this is not the case, adjust the High Pressure Switch by removing the rubber plug from the center of the pressure switch between the two wire leads. Insert a 5/32 hex key into the center hole and rotate counter-clockwise by a ½ turn. Repeat previous steps until you are able to get continuity at the correct time. If you are unable to get continuity after 4 times of repeating these steps (2 turns max.), replace the High Pressure Switch. Step 6.4 Motor Failure Switch T-Dolly to MANUAL mode and push the RETRACT switch to retract the drawbar. If the drawbar begins to retract, continue to step 6.5. Check voltage across positive and negative posts on motor while holding down RETRACT switch. (Figure 2, Item 9 and 10) If voltage is present and motor is not running, replace motor. Step 6.5 O-Ring Failure Verify if any O-rings are extruding from the face of the aluminum manifold. (Figure 1, Item 12) Replace any O-rings that are extruded. T-Dolly Troubleshooting Guide, Rev. D, Firmware 1.14 Page 14 of 48

Remove Cartridge Valve from the manifold. Have something available to plug the port once the Cartridge Valve is removed. Check for any torn, ripped, missing O-rings or backer rings. (Figure 1, Item 7. Figure 8) Replace any torn, ripped, or missing O-rings or backer rings. Reinstall the Cartridge Valve back into the aluminum manifold. If all O-rings and backer rings look good, continue to step 6.6. Step 6.6 Cartridge Valve Coil Failure Check the 5-amp fuse to the Cartridge Valve Coil. If the fuse is blown, replace the fuse with a new 5-amp fuse. Check the resistance of the Cartridge Valve Coil. (Figure 1, Item 7) To do this, unplug the Weather Pack connector. Plug one of the leads of the multimeter into the Weather Pack terminal that leads to the coil. The other lead will go onto the grounding post of the motor. The resistance should be between 3.5-4.5 ohms for Unit numbers 899277, 899546-899745, and 937990. If there was less than 3.5 ohms, replace the coil. The resistance should be between 5.4-6.4 ohms for Unit numbers 899746-899835. If there is less than 5.4 ohms, replace the coil. Verify the T-Dolly will retract by switching the T-Dolly to MANUAL mode and holding down the RETRACT switch. If T-Dolly retracts, return the T-Dolly to service. If T-Dolly does not retract, contact technical support. If all of these steps were completed and nothing was found, contact technical support. ERROR CODE 7: LOW OIL Step 7.1 Low Oil Switch T-Dolly to MANUAL mode and retract drawbar completely. Unscrew breather cap on reservoir and check oil level. (Figure 1, Item 13 and 14) The oil should be ½ inch from the top of the reservoir. If the oil is lower than a ½ inch from the top, fill the reservoir with Dexron-III (or higher) ATF fluid until this measurement is reached. If the fluid level does not need to be adjusted, continue to step 7.2. Step 7.2 Loose/Damaged Connector Disconnect Weather Pack connector that is attached to float switch. (Figure 6, Item 1) Inspect both sides of Weather Pack connector for corrosion and/or loose pins. (Appendix D) If corrosion and/or loose pins are found, repair as necessary. If there is no corrosion and no loose pins, continue to Step 7.3. T-Dolly Troubleshooting Guide, Rev. D, Firmware 1.14 Page 15 of 48

Step 7.3 Damaged Wires Check wires leading to float switch from controller. (Figure 1, Items 1 and 6) Replace any damaged wires. If there are no damaged wires, continue to step 7.4. Step 7.4 Oil Level Sensor Failure Check for continuity at the weather pack connector that is attached to float switch. (Figure 6, Item 1) If there is continuity, clear the error code and return the T-Dolly to service. If there is no continuity, remove float switch from reservoir. (Figure 6, Item 1) Check that the float is still attached. If missing, remove float from reservoir and replace with brand new float switch. (Figure 6, Item 4) Check the C-clip underneath the float and verify it is not damaged. If damaged, replace it. (Figure 6, Item 5) Check for float switch to change state. Check continuity at the Weather Pack plug of the float switch. When the float is resting on top of the C-clip, there should be no continuity. When the float is raised off the C-Clip as far as possible, there should be continuity. If there is continuity while the float is resting on the C-clip, then the C-clip needs to be removed and the float needs to be flipped over. Once the float is flipped, reinstall the C-clip. Recheck the continuity in the float switch. If there is no continuity when float is raised, replace the float switch. ERROR CODE 8: LOW BATTERY Step 8.1 Battery Voltage Low DO T CLEAR CODE. Check voltage of the battery. (Figure 1, Item 9) If battery is below 12.1 volts, connect T-Dolly to a power supply using the 7-way cable. The error code should clear on its own. Continue to step 8.2. Step 8.2 30-Amp Circuit Breaker If the T-Dolly has a 30-amp circuit breaker, contact Silver Eagle Manufacturing for a fuse kit replacement. Part number 37026. Continue to step 8.3. Step 8.3 Battery Connection Remove positive ring terminal from battery. T-Dolly Troubleshooting Guide, Rev. D, Firmware 1.14 Page 16 of 48

Plug T-Dolly into power supply using the 7-way cable. Check voltage of the smaller gauge wire at LOOSE positive ring terminal that connects to the battery. The voltage should be between 14-14.5 volts. Disconnect the 7-way cable from the power supply. Reconnect the wires to the battery. Check that screws are torqued to 50 in-lb. on the battery. (Figure 1, Item 9) Once screws are torqued properly, and if voltage was in the correct range, release the T-Dolly back into service. If the voltage was outside the range given, continue to step 8.4. Step 8.3 DC-DC Converter Connections Disconnect plug from DC-DC Converter. (Figure 1, Item 11) Check for corrosion and/or loose pins on connector and where connector seats. If no corrosion or loose pins are found, plug connector back into DC-DC Converter. If corrosion and/or loose pins are found, repair components as necessary. (Appendix B) Remove A and B connectors from Controller. (Figure 1, Item 1) Check for corrosion and/or loose pins on connectors and where connectors seats. If corrosion and/or loose pins are found, repair components as necessary. (Appendix C) If no problem was found in any of the above steps, contact Technical Support. ERROR CODE 9: WEAK BATTERY Step 9.1 Battery Failed Measure the resting battery voltage. If the resting battery voltage is below 12.6 volts, connect the 7-way cable to a power supply and charge for two hours or until the battery is accepting less than one amp from the charger. TE: Charging time depends on the battery s state charge. Two hours is the most a battery would need. Disconnect the 7-way cable from the power supply. Once the resting battery voltage is above 12.6 volts, connect a multimeter to the battery terminals. Note the end of test voltage (ETV) on the battery while running the pump. ETV is measured while the pump is running, and after 10 seconds. To run the pump, flip the Mode switch to MANUAL. On the direction switch press EXTEND, while monitoring the battery voltage. The end of test voltage (ETV) should be equal to or greater than 9.60V @ 70 F or above. See Table I for temperature adjusted ETV values. If the ETV is below the required value, remove the battery for further load testing. (Appendix A) T-Dolly Troubleshooting Guide, Rev. D, Firmware 1.14 Page 17 of 48

Check voltage at LOOSE positive ring terminal that connects to the battery. The voltage should be between 14-14.5 volts. If the voltage is within this range, continue to step 9.4. If the voltage is out of this range, check DC-DC Converter connector and controller A and B connectors for corrosion and/or loose pins. (Figure 1, Item 11) If there is no corrosion and no loose pins, continue to step 9.3. If corrosion and/or loose pins are found, repair as necessary. (Appendix B and C) Check voltage again after repairing pins. The voltage should now read out between 14-14.5, if it does not, continue to step 9.3. Step 9.3 30-Amp Circuit Breaker If the T-Dolly has a 30-amp circuit breaker, contact Silver Eagle Manufacturing for a fuse kit replacement. Part number 37026. Continue to step 9.4. Step 9.4 O-Ring Failure Check all internal O-rings of the valves on the aluminum manifold. (Figure 1, Item 12) If there are any torn or broken O-rings, this could allow oil to flow through ports in the manifold where it should not be flowing. This can cause the drawbar to take longer to fully retract or extend causing the battery to work harder than it should normally. Replace any torn or missing O-rings or backer rings.

If the motor is not running, skip to step 13.8. If the motor is running, continue to step 13.2. Step 13.2 Broken Wires Check to verify there are no broken or damaged wires going to the Proximity sensor for the lock hoop. (Figure 3, Item 2) If there are broken or damaged wires, repair as necessary. If there are no broken or damaged wires, continue through the rest of this step. Check the 5-amp fuse to the Cartridge Valve Coil. If the fuse is blown, replace the fuse and go to step 13.3. If the fuse is fine, continue through the rest of this step. Check to see if there are any broken or damaged wires leading to the Cartridge Valve Coil. (Figure 1, Item 7) If there are broken or damaged wires, repair as necessary. If there are no broken or damaged wires, continue to step 13.3. Step 13.3 Cartridge Valve Coil Check the 5-amp fuse to the Cartridge Valve Coil. If the fuse is blown, replace the fuse with a new 5-amp fuse. Check the resistance of the Cartridge Valve Coil. (Figure 1, Item 7) To do this, unplug the Weather Pack connector. Plug one of the leads of the multimeter into the Weather Pack terminal that leads to the coil. The other lead will go onto the grounding post of the motor. T-Dolly Troubleshooting Guide, Rev. D, Firmware 1.14 Page 21 of 48

The resistance should be between 3.5-4.5 ohms for Unit numbers 899277, 899546-899745, and 937990. If there was less than 3.5 ohms, replace the coil. The resistance should be between 5.4-6.4 ohms for Unit numbers 899746-899835. If there is less than 5.4 ohms, replace the coil. Verify the T-Dolly will retract by switching the T-Dolly to MANUAL mode and holding down the RETRACT switch. Continue to step 13.4. Step 13.4 Oil Flow Extend Disconnect the hydraulic hose from the base end of the cylinder. (Figure 9) Place the open end of the hydraulic hose into the reservoir and hit the EXTEND switch for a couple seconds. You should see oil flow out of the hose. Reconnect the hydraulic hose to the cylinder. If there was no oil flow, skip to step 13.6. If there was oil flow, continue to 13.5. Step 13.5 Oil Flow Retract Disconnect the hydraulic hose from the rod end of the cylinder. (Figure 9) Place the open end of the hydraulic hose into the reservoir and hit the RETRACT switch for a couple seconds. You should see oil flow out of the hose.
