mega stim testing (question#2)

[thedude]

hello out there_im powering my megastim with a 9V battery only and i have power everywhere im suppose to but i have no ground at the db37 connector will i get a different result if i use a p5 wall wart power source?

will i get a different result if i use a p5 wall wart power source?

Not likely, but I would use the wall wart anyway.

Just one mans preference of course...........

Some clarification: your voltage reading will probably be different because of the difference between the output voltage of the battery and the wall wart, but otherwise your results should be the same.

i should see system voltage between pin 1-2 of the "megastim" with the use of a dvom right. do you know of a different wiring schematic other then the one illustrated on the "megastim" assembly page. the ground path that is described looks kinda strange to me.
