can it be done like every other piston engine?

remove a spark plug, get a good ground and start the car?

thanks a lot

I recently was diagnosing my FD ignition system and tested for spark that way. I bought a new set of plugs to use for the spark test. I pulled the green circuit relay so they car didnt start. I got under the car and using one new plug, I unplugged each spark plug wire, plugged in the new plug and using some insulated pliers, held the electrode close to the block while a friend cranked the car.

 

you can actually get a spark plug tester which is like a 12v tester. Goes between the plug and wire. Lights up if there is current going to the plug. Got mine at harbor freight tools for $1.99. You canalso do it the old fashion was like mentioned above. Make sure you uses insulated gloves or pliers. I did it once on my brother's FD and shocked not only my hand but my knee since it was grounded to the fender

 

alex yes we did it like that to check for a strong blue spark

did you get another rx-7

 

thanks guys
