When testing your Harley Davidson ignition coil you will be testing ohms resistance. Damage to the coil and ignition will result and will NOT be warranted. Install the 19368 spark tester between the high-tension lead and a good engine ground. Measure resistance between coil tower and each terminal of distributor 2-pin connector. the incorrect type of HT coil, IE one that does not have the metal frame around the coil body this maybe the cause of poor starting. A Q45 forum / Cima forum for the President of Infiniti's lineup. Primary resistance is the measure of how hard it is for current to flow through the primary windings. A working ignition coil will give a reading of between 2.5 – 5 k ohms. Coil Warning: DO NOT use a low-resistance or an HEI-style coil. Ignition Coil: The ignition coil is probably the easiest thing to check and therefore the first thing to check when embarking upon ignition system troubleshooting. Step 2. Decided to leave the group of brown wires on that post instead of letting them hang loose in the engine compartment like I found them. How to Tell if an Ignition Coil is Bad. 2000 Y33 q45 Ignition coil Ohm test explained bad good. Spin the engine over (at least 250 RPM) and watch for spark in the tester window. If the coil fires when you cause a momentary ground, then the ignition would be suspect. Set the multi-meter to the 20 k ohms setting. Ignition coil’s primary resistance should be ranging between 0.4 and 2 ohms. However, for experts, identifying the problem is quite easy; but, it can be brain-racking for newbies or who isn’t familiar with motorbike mechanical issues. Recommended - DC1-1. Step 1. It’s advisable to check at the manufacturer’s specifications for correct readings. The coil is probably the easiest thing to check and therefore the first thing to check when embarking upon ignition system troubleshooting. Many threads point to possible ignition coils going bad. If resistance is not .6-.8 ohm, replace ignition coil. (4- and 6-cylinder) engines: Use a coil that has resistance, measured between the + and - terminals of the coil, of at least 3.0 Ohms (Ω). So, I'm testing the primary windings on both ignition coils to find resistance around 3.2 - 4.2. I have about 2 ohms on the primary I was able to find the spec for that and it is good. so if the pick-up coil is suppose to be 130-190 ohms and i get a reading of 145.6 k-ohms then this is out of range and the part is bad… no?? Incorrect or low quality HT coils should be replaced for the correct sort. If you own a Harley Davidson bike, one of the things that might bother you is the ignition coil. Since the coil is the center of the system, it has to be working right or the car will not run right. I think (correct me if I'm wrong) the stock coils are 5.8 Ohms. Ive ruled out Flooding and it does have spark, but I'm wondering about the ignition coil that once it heats up it fails. Canister Coils are designed for those stock or street/strip applications while E-Coils are engineered to suit high-vibration, high-performance applications and Direct OEM replacement FORD COP and GM LS Coils round out the line.
