So i need to set my timing and i got a timing gun yesterday, and i dont know if im using it right cause the gun isnot working. and i cant find the reciept to take it back. i followed the instructions but i dont know if it is just me or if the thing is broke. i hooked the red cable to the battery and the black ground on the engine, then i put the other thing over the #1 spark wire and it isnt lighting up. i even changed wires to the stock one to see if it would work and it didnt.
