What am I doing wrong?

[E30//MAN]

I'm trying to power something that's 12V DC. I've got a switch with 3 poles, supply, load, and groud. I've got the supply, coming from the ignition, load going to the unit I'm trying to power, and ground the chassis. The thing I'm trying to power works fine if I just tap into the ignition ground and power, so I don't know what I'm doing wrong.

Switch POWER: ignition-> supply (Hoped to put a fuse in between)
Switch GROUND: chassis -> ground
Switch LOAD: switch -> chassis
:help

Does it matter if I twist the unit's ground and the switch's ground wires together?

If you are talking about the typical Radio Shack switch, they SUCK! the chassis of the switch deforms, making the contacts distort, thus no contact. Plus, they break! Junky switches are the norm today. If no output, replace.

Good luck!

Just out of curiosity... what is this 'thing' you're trying to power?

electrical drawing diagrams are really helpful... draw one on paint and attach it to the thread, i'd love to see where ur going with this too....

Black lines are what I'm trying to do, blue works right now.

It's top secret right now, because I don't know if I'm going to be able to do the rest fo the job or not.

are you sure you got your ignition wires correct? and not crossed perhaps?
