Ummm O.K.
If it's a 12 V relay, you'll need a 12V source (car battery, or charger). Energize the coil (if it's a mechanical relay, you'll hear it click), check the pole(s) for continuity with a meter.

Clicking isn't enough.
I test one that clicked but the clicker had bad contacts in it. Obviously, electricity was going no where.

I bought a 12 V battery from radioshack to test my water injection kit harnesses. For about 28 bucks you can get a rechargeable lead acid 12 V battery. They are very small and convenient.
you can hook your relay up to that, apply power to the 30/51 and 86 source, hook your ground to 85 (maybe connected to a switch and then your devices to 87/87A. It works great.
Just make sure your 30/51 and 87/87A are fused.

Damn it I shouldn't have thrown my old one away. I would have taken a pic of it.
