Jim,

You say only 8.75 volts at the red wire. Did you try a different ground? A dirty or lose ground can cause this issue. Once you get this problem fixed, the lift should start and run without any issues. The code will no longer show on the dash, but it will be stored in the VSM. The technician service code is always five numbers. Also, need to check CPS55, the red wire goes from the VSM through this connector. Good Luck.
