cleaned everything....just keeps throwing an E1.....should the system be making any sounds at all?

[Discharge Valve]

I sure hope I'm not the first...I'm actually a mechanic this isnt even my bike but I've had it at the shop and have been lost....I guess I should just clean the connections from the CLASS computer all the way to the rear connections with rubbing alc?

thanks!

can anybody tell me what the class system discharge valve looks like? I can see the compressor and all but have NO idea what the discharge valve remotely looks like. My system keeps throwing an E1, it threw E4 before then I soldered it, it worked for about 5 minutes now its throwing E1..

thanksalot

[Class e1]

wondering what the E1 code means?

[Class system]

okay I resoldered the connectors and it fixed the E4 code and worked for about 5 minutes...now it's throwing an E1....any ideas or input?

[Class system]

Yes I have it on ACC and it throws up E4.....kinda confused...

[Class system]

not new system, new class controller

[Class system]

See I ordered a completley new system....so would this still be the cause of the problem?

[Class system]

Hello, I work at a repair shop and had a Yamaha Venture pull in, its an '88. The class system keeps throwing an E4 error message. I looked it up and I guess it means there is no voltage coming out of the air sensor. Now, when i turn the key I imagine I should hear the compressors kick on, but I'm getting nothing. Any idea on where I can get the full class system minus the computer itself?

Thanks!
