What's the best way to replace the Cluster Voltage regulator?

Ok so I went to check the limiter output to the guages and I found I keep blowing #6 3 amp fuse. I thought it just powered the brake and oil light set but as soon as I replaced it and pugged the limiter in it blew again....ugh.

So I'm guessing I have a short somewhere? Anyone had this happen before?

It just keeps getting better :-(
