Folks,
I just use an old used spark plug for a tester.
I have soldered a smaller battery type, brass spring clamp to the base of it.
Clamp it to a good ground, & then use you're remote start button.
And, coincidentally, I have some old spark plugs for sale !!!! ( p-mail me
for prices :) (kidding)
cheers,
