Of course it's just as likely both electrodes will glow, just one brighter than the other which indicates an asymmetrical AC waveform. If both electrodes glow, it's certainly AC but if only one electrode glows, it's definitely DC. Try connecting a neon lamp to the output of the ignition. Unless there's something to prevent the reverse current flow, the output voltage will oscillate a bit, after each spark. You'll probably find the spark rate decreases, as the battery voltage drops, rather than the sparks getting weaker. When the voltage on the capacitor exceeds a certain voltage, the spark gap or thyristor fires, discharging it through the ignition coil. The ignition probably has two stages: a blocking oscillator, similar to that used in xenon flash unit and a high voltage ignition, consisting spark gap, neon or thyristor connected to the ignition coil When the button is pressed, the blocking oscillator boosts the voltage to a couple of hundred voltages and charges a capacitor. As mentioned above it is better to add a ground but sometimes we have to use a igniter module with more outlets than we need, even after we attach one of them to a rground position.An electronic ignition will probably produce a damped AC pulse. This creates a closed circuit and does not hurt anything.
When we have a 6 outlet module but have 4 or less wires to plug into the module then we can use the jumper wire to attach 2 spades to the same wire. A jumper-wire is a small wire with a female attachment on both sides.
AAA BATTERY PULSE IGNITER INSTALL
Some of these will install to spark plug electrodes inside the barbecue and some will terminate at a ground. It is possible to add a “jumper” wire but the system will work properly for longer if we ground all the outlets to electrode wires.
AAA BATTERY PULSE IGNITER GENERATOR
If we have a spark generator module that has 6 outlets we have to have all six spades connected to wires. Two outlet sparking module test against a steel cabinet once the module is removed from the gas grill.Īlways note there can not be any “empty” outlet spades on the barbecue grill ignition module. On these images I removed the module from the BBQ Grill and held the metal outlet spades about We want to place the module where the button can be pressed but pressed with the rest of our hand, and body away from the back of the module where the raw outlets do not have anything plugged into them. If you go through this process with the module still installed in the barbecue the tip of a screwdriver is usually the best way to test the spark, and often the only tool that we can extend into the controls area. This can be something attached to the grill ike a stainless steel grill hood or the control panel or eve the tip of a screwdriver. We test the spark by placing the module against a pice if steel.
Once the module is in the palm of your hand and the battery is installed properly - in this spark generation module the AAA battery is installed positive-end-down - we want to test the spark. Module with battery and button being tested for sparks.Īlways start using and testing the module with a new battery installed. We can do this from inside the barbecue but it is difficult to get-to and difficult to see. To test the module we want to see if it will spark when the spark generator is not attached to the electrodes. The spark generatpr is just a small and simple electrocal product and they do not last forever. Sometimes humidity or moisture or excess heat or something can cause the module to stop working. This is the way to repair the ignition about 90 percent of the time. Usually if the ignition is not working, we need to get into the lower fire box of the barbeque and clean the tips of the electrodes with a little degreaser and a small file or a little sandpaper. If the tip of the electrode or the steel next to the tip of the electrode has grease, marinade, dirt, etc on it then the spark does not have a clean place to spark against and it will not spark, will not ignite the gases. Porcelain and then continues through the porcelain to spark at its tip. All in one spark generator module sparking against steel shelf
