How do I do this? Do the fuel pumps require the full 12 volts? I hooked up the pump to a 12v spower source, it pumped. I hooked it up to a 6v source, nothing. Checked the voltage it is recieving incircuit... 8.4 volts. Relay has a resistance ov 1 ohm I believe... checked with an ohmmeter. I didnt know it was supposed to have resistance... or is it? please help!
