Having problems with your Dodge Ram 1500 ?
How do you check wires leading to coil on a 2006 dodge ram 1500 slt 2wd
The best way to determine if they're good is to:\015\012\015\012-be sure that the grips at each end snap tightly to the cap and to the plugs. If they're loose they may misfire or fire with weakened energy\015\012\015\012-inspect the length of the wire for cracks, dry-rot, or wear marks that could compromise the wire. There should be no splits, cracks, or openings in the jacketing. If there are, the spark could arc through the damage to ground, causing a misfire.\015\012\015\012-at the plug end, look for any blue marks or burns that would indicate arcing inside the cylinder head. You should see no burn marks on the boots (the part that goes over the plug).\015\012\015\012-use a digital meter ($10 at a parts store), set it to impedance settings (the horseshoe-shaped omega symbol), and put a probe at each end of the wire, touching the metal grips. You should see a low number. If it says "OL" on the meter, that means Out of Limits, or that the wire is open/broken. The lower the number, the better the conductivity of the wire.\015\012\015\012Long as these factors check out, you should be fine using the wires.
