COUNTERWEIGHT AS 1400327 - Caterpillar

A. The TILT lever is not held in the TILT BACK position.For the TILT lever to be held in the TILT BACK position: Connect a jumper wire across the oil pressure switch.1. Check for power to the solid state switch. a. Disconnect the P/W wire from the connection on the solid state switch marked FUSE.b. Check this wire for machine voltage (12 volts) with a 5P7277 Voltage Tester. Connect the clip of the tester to the wire connector and touch the point to machine ground. 2. Check for correct operation of the solid state switch. a. Disconnect the P/DK BL wire from the connection on the solid state switch marked SWITCH.b. Pull the bullet connectors apart a small amount on the harnesses between the solid state switch and the electromagnet.c. Fasten the clip of the 5P7277 Voltage Tester to machine ground and touch the point of the tester to the pin connection of the solid state switch plug. There must be voltage. d. Put a jumper wire from the connection marked SWITCH on the solid state switch to machine ground.e. Again put the point of the tester to the pin connection of the solid state switch plug. There must not be voltage. 3. Check for continuity through the electromagnet. a. Disconnect the solid state switch harness plug from the electromagnet harness plug.b. Check for continuity between the pin and receptacle in the electromagnet harness plug. There must be continuity. 4. The solid state switch and the electromagnet work correctly. The problem must be either in the alignment of the electromagnet and the plates on the lever, or in the external control circuit for the solid state switch. Check for the alignment of the electromagnet and the plate.a. Put a jumper wire from the connection marked SWITCH on the solid state switch, to machine ground.b. Move the lever to the TILT BACK position. The lever must stay in the TILT BACK position. 5. Adjust the position of the magnet or change the length of the linkage rod so that the plate on the TILT lever is in complete contact with the electromagnet.6. With the tilt
