I'm wanting to clean out the boost solonoid on my Classic, as several posts suggest this may be the cause of my low boost.
I know you have to connect green wires under the dash, then clean the solonoid out, but is it obvious which the green wire is - is it the same as the one to reset the ECU?
Also, exactly which part is the solonoid?

Why don't Haynes do a manual!!!

cheers

From my prev posts




Pipes off
Sol. unbolted (bottom nut likes to go for a walk under the air filter assy.)
Connect green wires under dash
Get can of brake cleaner ready
Hold sol. in large rag
Turn on ign. DO NOT START THE ENGINE
All valves, sol. etc and fan start to cycle, so lots of clicking / whooshing going on.
At this point Sol. should be pulsing away, so holding it in the rag give it hell with the brake cleaner up both ports. Really give it a good internal soaking until you
A- get tired
B - Get completely covered in dirty fluid
C - fluid running clear out of sol. (and up arm / side of car) is clear.
Once satisfied give it a blast for luck then turn off ignition and let valve drain / dry out whilst turning your attention to the pipes.
Remove pipes one at a time (remember which one goes where!! think the bent ended one goes to the back ) and again give them hell with the brake cleaner, Let them dry out for a couple of minutes and then re-fit.
I also cleaned out the small Dia. hoses that run from the T piece to the actuator. If you have a look you will see bloody little clips that shred your fingers!!

Refit sol. (retrieve bottom nut from under air filter assy)
Complain about the ridiculous size of hand required to fit bottom nut (retrieve bottom nut from under air filter assy again) (remove air filter assy as an option - its a lot easier to get at the little bugg@r)
Re-fit pipes after routing back through adjustable cable ties

Start her up, and go for a bit of a run

And that’s about it!!!

Hope this helps
