Class E-4 error

[Ride2much]

I found the CLASS re-soldering repair steps in the Tech Library. I am not real comfy attempting this repair, so before I tear into it,does this controller control anything other than the Class system, I cannot afford any bike down time right now if I hose something up.

If you are referring to re-soldering the connector pins in the Class controller then the answer is no those connectors only affect the Class. I was in a similar situation to you. My Class only worked if I jammed the controller connector with a piece of cardboard and I was never very successful at soldering. Anyway, I tried it and didn't get it fixed. Turned out my soldering iron wasn't getting hot quick enough probably because it was a cheap one. After a while I got a better soldering iron and the job got done real easy. As is probably mentioned in the Tech article, the solder needs to be re-flowed on the connector pins. That needs to happen fairly quickly or the heat will transfer too far and start to melt the solder farther away from the pin which can lead to cross connecting the traces with dribbles or runs of solder.

You can still ride with the controller out of the bike. If you are not confident then find someone who has electrical soldering experience and smooze them into doing it for you...

i did mine and camos was right your soldering gun cant be the smallest one. big ones too powerfull. bought a pencil type from manerds the size is on package. buy the middle watt one. take you time and use pencil eraser on connections before soldering. cant remember if that was on that controller or cmu instructions. but made a difference for me.

Just a couple of hours ago I also re-soldered the particular circuit board pins as after I took mt recently acquired 89 RSV home on a bumpy road it gave me the E4 message, and I also will chime in and say many many thanks, I was just about ready to buy another CLASS,
