In this test section we're going to make sure that this non-sparking ignition coil is getting an activation signal from your Chevrolet TrailBlazer or GMC Envoy's fuel injection computer. This will fire the coil. share. i have a honda gx 390 that i have no spark. Had one wire to the disributer the other directly to the battery. hide. The coil still receives voltage, but the amount may be reduced by a resistor in the "run" circuit. Make sure all lights and accessories are off. Any break in a conductive material, like a wire, creates an open circuit. Oddly, he also connected the negative terminal first and then positive and I really thought that the positive Disconnect any ground wires or additional connections to the ignition coil. When disconnecting, pull the wire at the boot to prevent damage to the wire. Ignition coils retrieve energy from the battery, which is usually at least 12 volts. Replace the coil with a good quality new one, make sure you attach and tighten the leads correctly, plug in the top cable that goes to the distributor, turn the key and you should be good to go! The voltage source is the normal Grubee magneto rotated by an electric motor to power a Grubee stator coil . Corroded connections can have enough resistance to essentially create an open circuit. Once the engine starts, the switch is released to the "run" position. With the nice weather we are having here I was out trying to start a pending project (46 dodge truck) was not getting any spark from coil. If your vehicle is behaving erratically and you have problems with it running smoothly, it could be showing signs of ignition coil failure. I was tightening the spring on my black right sparking launcher when the coil popped out anyone have an idea on how to fix it? Read: Armature Reaction in DC Motor Problems associated with meeting these requirements can be as simple as a corroded wire or weak battery. The condenser needs to absorb the electric spike, and according to the wiring diagram for this cycle the tach is tied into the black ground wire on the left side coil. You can use a set of wire removal pliers, if the boot is hard to reach. terminals. Yes, arcing and sparking is due to differences of potential, but that doesn't mean there's a problem. still no spark. I didn't have any data loaded to the Tweecer unit. You can replace the secondary coil wire on an engine that uses one with an equal length of vacuum hose and the engine will start and run. – Robert S. Barnes Mar 4 '16 at 14:05 Partial maybe, but I can guarantee I'm sharing in that "title" myself, Coil continually sparks to ground without engine running, http://s154.photobucket.com/albums/s247/patrickmx2/. I found out where i was getting the strange voltages (around 4 volts on the ground wire of one of the coils). Most ignition coils are mounted to the engine by two 3/8″ bolts bolts driven through the laminate. Singing Tesla coil or musical Tesla coil: This is a Tesla coil which can be played like a musical instrument, with its high voltage discharges reproducing simple musical tones. Place the coils a good distance apart and connect their ground connections using a single wire. The coil output takes the path of least resistance so either a carbon track, a cracked coil, or open circuit voltage meaning the coil output is open from the coil to the plug somewhere is happening and not enough voltage to fire the plugs. by 2Shaker » Wed Aug 08, 2007 10:08 pm, Post To check for ground, we're gonna' do a simple multimeter voltage test on the wire labeled with the number 2 in the photo above. Certain requirements must be met for an ignition coil to produce the high-voltage spark that fires an engine. However, coil systems tend to cost more to install as compared to leaf spring systems. Gather the ground leads from the secondary coil, the strike ring, and the Terry filter. An ignition coil is not sparking (TEST 1). Check the voltage. The surge voltage due to arcing ground can remove by using the arc suppression coil or Peterson coil. 5. The article, “A Close Look at Charge Deposition from a Pulsed Tesla Coil System,” by Richard Hull and Scott Fusare, ESJ 35, pp. The test light should light up indicating power on the negative side of the coil with the key on and engine off.
