Well first off, I get NO continuity buzzer when I connect the wires, but at 20 Ohms, it reads 7.0 on the shortest wire. They have 180,000 and I think they are origionals. But they look pretty good.
Not sure what that means though. Anyone good on this electrical?
Regardless of what they test or should test out, I'll give you a bit of advice. Change them every 60k miles. The wires breakdown and start allowing spark to leak through the insulation. This will lead to a misfire situation eventually.
Right, but I don't know when they were last changed. Got it used. They do say '1999' on them, and its a '99 truck, so its probably time but I think at least the first wire Ohms are good, at around 7.00 at 20K Ohm
