Awesome! Thanks mdjensen22! Can you tell me which transistor and diode to use?

Berkeman, I appreciate you replying and helping me out! So I ran a bench test with a variable AC/DC power supply and found that the relay did not switch at 5.75V, 1.7A, but DID switch ON at 7.65V, 1.65A Couldn't a simple transistor circuit be made to amplify 5V, 0.25A ? I found a transistor...

so according to the seller, there's no data sheet for the relay... How can I test the relay to see what the minimum current to activate the coil would be? Would a variable resistor or something, help?

I found a similar one on ebay. I messaged the seller to see if he has a data sheet... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=370478844324

I'll do some research on that and post it ASAP... thanks!

Here's a pic. thanks for your help!

Hmmmm... I'm not sure... How can I find out? I have the relay...

Greetings E.E. Gurus! I'm a noobie in need of your guidance! Here's the situation: I have a 5V DC, 0.25 amp (1.25W ?) power source from an oil pressure switch wire on an old truck that is activated only when the engine is running. My goal is to activate a 12V DC, 2.5 amp, 30/40W...
