Question about onboard air compressor

Post by wingpilot08 »



I previously owned a 96 1500 SE, but am currently working on my brothers 88 1500. Since I no longer have the service manual or owners manual I need a question answered.

The onboard compressor for the air shocks may be having an issue and I just need to confirm if to use the compressor is it necessary to have the engine running or just have power on? Currently I have the wing apart to work on it, saddle bags will be removed to do more inspection.

Over the next couple months I will be doing all fluids, check timing belts, brakes and other assorted maintenance.

I know there is tons of info on this site, so no doubt I will be doing searches as needed.

Thanks for any info or help in advance!

I’m currently riding a 2008 HPNA.

I believe you must have the engine running, in neutral.
If you have it apart, remove the compressor, open it and take out the desiccant beads and dry them out until they turn blue again. You'll probably find that they are pink when you remove them.
Good luck with it.

On the later bikes you can fill the suspension in ON, P or ACC. The bike should be on the center stand when doing this.
However, the outlet function requires it be in P.
The 88-89 are odd ducks so they might be different.

Yeah..it’s apart. Just extracted a lot of PO wiring that was a real cluster f$@k!! Waiting on additional parts. Going to replace brake fluids, need to replace rear pads. Will also be digging into the timing belts. It has over 120k miles and unfortunately PO didn’t keep records.

Thanks for the quick responses!!👍🏻
