pipes, compressor, bags, fuse and a relay!

[onetwentie]

Having looked at the pump/compressor again, I realised that there is only one rubber pipe, which comes out vertically (though yes it is connected twice to the pump). I don't understand the schematic if i'm honest, so a bit stumped there.

Anyway another update:

took the pump down to a local guy who repairs gas systems for refridgerators and the like. He offered to put a gauge to it, and initially it looked like the needle on the gauge was pulling back, as if to show suction as opposed to pumping air out? he also suggested something to do with a one way valve, but I'm already confused!

Anyway, after a little while the pump decides not to work again! (and this is consistent with when I tried to give it a 12V feed whilst it was still on the car, I could swear it didn't actuate). So me and him both baffled we tested the wire further down the pump by piercing it with the probes from his multimeter, and yes there was power/current there.

The guy then concluded that the motor must be duff and suggested that I look at it. He actually encouraged me to open it and showed me what I would need to do.. so guess what? I did:





So as can be seen, most of the inside of the motor is a mess. The bushes (I believe that's what they're called? the 2 spring mounted metal things? seem to be okay.

I'm thinking to open the other side where the riveted panel is (the side with the crankshaft?) to see if I can open it more?

what do you think Del/Others?
