cleaning GL1500 Air compressor switches

Post by sweptwing »



Hey everyone. I have found numerous articles regarding the air compressor control switch bank on the 1200 but cant seem to find any on the 1500. I have an 88 and a 90 and both have the same issues. The switches (most particularly the P.Check button) are very sticky. In fact most of the time you have to push the p.check button about 20 times and hold it with the correct amount of pressure in the correct spot to get it to read. Is there a safe way to disassemble the switch bank and clean them all out? Spraying contact cleaner in the front of them seems to do no good. Thank you all for any input you may have.

I had the same problem with my 88. I tried to take the assembly apart, but the plastic is old enough and brittle, the holding tabs broke. I ended up getting a used one off E Bay and sprayed a bunch of CRC electrical contact cleaner in there to prevent the problem. So far so good. I would still try the CRC and just work the switches a bunch of times to try and clean them up.

Thank you for that. Ya I wondered about trying to disassemble it with it being so brittle. I have contact cleaner but maybe will go try some CRC brand next and see what happens. Thank again.

They can come apart but the older the plastic the more brittle. I have a '96 Aspencade and I used small screwdrivers to bend the plastic just enough to let the tabs clear the slots in the housing. I used Triflo and WD40 and it made the switches work normal again. You might first try sliding the spray nozzle straw between the rocker and the housing to see if you could get enough lube or cleaner to the contacts without pulling them apart.

I will give that a try prior to ordering a replacement set of switches. I need to search for directions on how to remove the switches next. Thanks guys.

I would NOT use WD40. It is lube but it does attract dirt and dust. Spray with contact cleaner and work them several times

Joe beat me to it. WD-40 tends to clean really well as it flushes out all the dirt and dust. However, it leaves behind an oily film designed to prevent corrosion. That's great for steel parts, but it's terrible for electrical contacts, where it quickly collects more dust and grime, and causes the switch to stop working even faster.

Use a dedicated contact cleaner that leaves behind no residue, CRC is the brand I have used for years.

I understand the good advice about the WD-40. And I have used the contact cleaner but it just doesn’t seem like there’s much lubricant involved so wouldn’t the parts wear out faster?

Went out and got some crc and started with the cruise switch. Ended up taking it completely apart along with the 3 little springs and completely cleaning it because spraying the cleaner in the closed switch just wouldn’t quite do it. Allot of work but it now works great. A agree with the wd 40 statement. It works great but will more than likely have issues sooner than later bs using contact cleaner. Will let you know how it goes. Has anyone removed the compressor switches? Not as clear cut as the handlebar switches.
