Nov 7, 2009. I have a Subaru Robins engine that runs great and I got the same output when I tested it. My confusion with it is the Manual says in Step 1: "Disconnect all ignition coil wires (including the spark plug leads) before testing." Than it says to test the primary circuit. Secondary test with caps on -26.5 ohms. I then added a additional ground wire from the frame to pin 3 still no voltage to the coil. They cut the coil wire from the wiring harness that go to the cdi, and ran them straight to the cdi. Question my positive wire on starter is grounded, I can take ignition switch from key and touch it to the frame and motor turns over. Second link gives detailed instructions for testing and diagnosing coil pack. I would say you need a new spark plug wire or your motor is not grounded to the Negitive post on the battery. Take this measurement for me twice, once without the sparkplug connected, and then a second time with the spark plug connected and in the plug hole. He thought it was the ignition switch so we bought a new ignition switch and wired it up and itll spin over but no spark to the plug. I know they mentioned the kill switch and mine was fine.

A new CDI and coil only cost less than 15 so I will order them. Plugs are 14 mm (0.55 in). Which wires are left over? Sometimes the cap itself can add extra resistance to the results. brought new cdi basic model, regulator ,coil, measured all AC voltages 80v from stator out put, 0.3v from stator trigger, 30v from cdi out to coil. The principle of operation of the ignition coil is relatively simple. Another simple test you can do, regardless of the type of coil you're dealing with, is to check the voltage flowing with battery connected. remove the wire from pin 5 on the CDI and see it it will start. Im thinking this means a switch, correct? I need help plaease. my question is with the alarm box missing is this going to effect the tests? Dont forget to ground back the pickup coil to the frame.

Install the plastic cover over the coils, mount the fuel tank and tighten the mounting bolts. Now before when it did fire I had the stator red/blk wire going into the Voltage regulator on the red wire pin ( normally the red pin is the battery input to the voltage regulator) So I had a Y connection on the red/blk stator wire one to the CDI and the other to the Voltage Regulator but it would spark and run. Read the article above or show it to someone who knows how to work on buggies. I ask because if you are using an analog type, the very small amount of voltage from the trigger wire may not be noticeable. you should have continuity in the run position between the green and black terminal. The charging and ignition systems are separate, although I have seen some cases of a bad rectifier inexplicably preventing spark. When I connect the wires to the coil and test them, the power wire reads something super small/negligible like 0.1vAC 4. and i have no spark. The fuse blowing problem is most likely related to the regulator rectifier and also likely a separate issue from what is preventing spark. my dad has a cater talon 150cc dune buggy that has bad wiring.
