How do I Bench test 73 Swinger gauge cluster

HI it's been awhile. I'm still working on my Dart. I getting my a$$ kicked with the electrical. Does anyone out there know how to bench test my dash gauge cluster. It was working for awhile then it stopped. I just need the lights. I have after market gauges in the consol. I did rewire the complete car. I got the Ron Francis Bear Bones kit. This harness has 16 wires. Marrying the stock 7 wires to witch of the 16 RF wires. I have 9 wires coming out of the dash cluster. The blue*white Is power. Tried power to it and grounding the back side of the cluster. nothing happened. Once I get dash lights working. I can drive her.. after I put the front seat in.
