Wiring help please

[r_mcrobie]

I just bought a MP-1 from ebay and open opening it to clean it out I notice that the green wire from the power input to the unit is not connected anywhere. Can anyone help me to find where I need to connect it?

What Version is your mp-1?You can find it on the eprom or does the unit has a topswitch?

If you're not sure post a pic of the inside so i can have a look myself.

It is v1.38. It has a top switch. I can take a photo of it tomorrow if it is needed.

Okay no pic needed then.The green wire needs to be soldered on the starground connection.It's located near the big caps.It's a big pad where all the ground connections will go to.
