carlton Posted March 3, 2005 Report Share Posted March 3, 2005 Any ideas on construction of a scope probe to view an automotive ingition secondary waveform? It runs any where from 12kv to 80kv depending on ignition type. The max voltage my scope can handle is 800v p-p or 400v (dc+ac peak). The probe must let the spark pulse through without loading it down. So maybe an inductive pickup that the scope probe can connect to.

audioguru Posted March 4, 2005 Report Share Posted March 4, 2005 Hi Carlton,Put a few turns of insulating tape around a piece of the high voltage wire. Wind 2 or 3 turns of hookup wire around the wire over the tape. You will get about 10V to 20V pulses from the hookup wire. Quote Link to comment Share on other sites More sharing options...
