Starter Relay - What am I missing???

Got home from work and only had a few minutes to tinker before going out. I disconnected the NSS wire and ran a jumper wire with alligator clips from the G (nss) terminal on the starter relay to where the battery ground wire is bolted to the engine and bingo - starts right up every time with the key.
So just to make sure I wasn't seeing things I probed the brown wire from the NSS again (disconnected from the starter relay) with my multi meter back to the + post on the battery, and I do see 11.5 volts. Gonna tinker with it again tomorrow or Sunday. Could it be that the ground is not sufficient and it's not getting enough amperage? Was thinking of testing the nss wire back to the positive battery post using a light as Killer6 suggested. I guess I should also check the technical service manual I bought (RTFM) to see what it says about testing the neutral safety switch. Any other ideas? My best one right now is to order a second margarita. Thanks for all your responses!
