Find the norton equivalent with respect to terminals a and b

[PLAIN]http://img821.imageshack.us/img821/7177/nortonequivalent.jpg [Broken]

2. Relevant equations

KVL, KCL

3. The attempt at a solution

I set i1 = .008 A

Then I found the rest of the currents.

KVL@ loop i2:

2000(i2-i1)+30=0

i2 = .0065 A

KVL@ loop i3:

-30+15000i3=0

i3=.002 A

KCL@ node D

i3-i4-.010=0

(.002)-i4-.010=0

i4= -.008 A

KVL@ loop iab:

30000(iab-i4)=0

iab= -.008A

I got the same current for i4 and iab, unless I did my math wrong.

Can someone check my equations and set up to make sure I'm even finding the right current for the norton equivalent circuit?

EDIT. I redid i4 by doing (i4-i3)=.010 A

I got i4 = .012 A so I'm not sure which current to o use.
