If you have a for/aft stance, its in the side cover below the Vehicle manager. there is a fuse card with 3 relays. They supply the power, traction and lift amps. Fail often from vibration, spikes. Cause many phanton codes (5G,5J)
By the way, any encoder on Raymonds should be checked with a voltmeter on A/C volts. When unhooked, you can test them by spinning the drive motor by hand. Same for the height encoder, unplug and put leads on each channel. There will a a 2 volt A/C voltage while turning the encoder. these encoders produce voltage. You can do a test in superword for the encoder, but this will fail if the power amp or wiring is bad.
