You can test the primary and secondary resistance of the coil. Primary being lead to lead and secondary being the same. that does not necessarily tell you whether it is good or bad with out a dynamic tester. secondary is the spark plug cap side. Primary side is the side with the wires

Coil is relitively cheap..like 20 bucks and that includes plug wires..A faulty coil will give you a weak spark and/or no spark in one cylinder.

motul is it possible for the coil to only fire on side until way into the powerband when the r's are high enough for the stator to be putting out a fiery hot current? cause it only idles and runs on one (the right) side until deep into the power. and where can i find a $20 coil, cause the local stealership wanted like $55.
