Took the 1500 out the other day for two up trip to the local coffee shop and noticed that the air compressor was not working. No worries for the short term as there was ample air in the shocks for the ride.
Next day went out first thing for coffee with my other riding friends, and noticed the speedometer was not working. No problem, intended to start the yearly maintenance the same day.
Stripped off the plastics, and looked into the air pump circuit. Have the OEM manual that includes the electrical section. Proved the air pump and solenoids worked. Checked the power to the switch, none. Confirmed power at the relay IAW the schematic; however, power through the relay from fuse #10 is at the relay but not on the downstream side. Bypassed the relay and the air circuit worked as expected, but no dash display when raising or lowering shock air pressure. The pressure indicator button on the switch works and there is a readout on the LCD display of the shock pressure. Plugged in a different relay and grounded the power from fuse #10 to ground and the air circuit worked as expected, but with no dash display of the shock air pressure change, increase or decrease. Stop increasing or decreasing the shock air pressure, push the pressure indicator button and get dash display.
Have perused the forum for info and found two older threads:

The only element that I have not taken apart is the dash, but I'm leaning towards the LCD display being the issue because fuse #10 power through the air pump relay has to go to ground through the LCD display. Any suggestions will be appreciated, and the search is on for the LCD.
The speedometer issue is straight forward. Took the speed cable off the wheel gearbox assembly, disconnected it at the dash, and no turn. After 25 years need new one. Took the front wheel off and disassembled the speedometer gearbox assembly. The plastic gear was stripped clean, and the 2 washers that are supposed to be there are not. Lots of play in the steel gear in the unit. Have new cable and gearbox assembly on order. Decided to bite the bullet and not jury rig the system.
Will be changing the front brake pads. Planning a trip across Canada and back, want to duplicate the trip we did last year to Dawson City and back. No issues and only used 1/2 quart of oil in 7400 Kms. Bike has some 174,000 Kms on it.
Going to paint the meter panel, shelter, rear speaker plastics and such to freshen up the look. Once you start painting pieces gets addictive and you "look" for items to do, go figure.
Always something.
Time to end my rant. Cheers
