I designed and built a test rig that operates three automotive distributors firing 8 spark plugs each. The rig is designed to simulate the actual operation in a vehicle. Mechanically and electronically the machine works great until the coils are turned on, then interference from the high voltage sparks cause voltage spikes in the trigger pulse. I have a sensor picking up on an 8 position gear to trigger the function generator. I tried to use shielded cable to the sensor but couldn’t eliminate the intermittent pulse. How do I reduce the electrical interference produced by high voltage spark energy produced by automotive spark plugs? I need some suggestions.
