How can I tell if a spark plug boot is good? Can I run a continuity test on it. If I use a test light using 12 volts on one end, won't it run through to the other end?
I'm not sure, the plug fires so fast That the light might not pick it up?...have you laid the plug against the jug to see if it is firing?I actually had the plug in the socket and held it to 12 volts and stuck my test light in the other end to check, and i got nothing. This would prove the socket is bad right?
I don't know, but it's possible. Do you have any friends that ride that would let you borrow their spark plug cap to try on your ATV? Since, they just screw off and screw back on, that would be a quick, easy way to tell if it's bad or not.It is a trx450. I know the volts are higher but wouldn't it still register from one end to the other. Just to let me know that there are no breaks or shorts in the boot. It wouldn't reduce the 12 volts enough to not even light up would it?
