24-inch WyzeProbe – Secondary Ignition & COP Probe

Scope COP Cylinder Fast | Captures Secondary Patterns | Works on Any Lab Scope

The WyzeProbe is a 24-inch long, fully shielded secondary ignition probe designed for fast testing of Coil-on-Plug (COP) systems—one cylinder at a time. It’s just the right length to reach into tight spaces like Ford Triton V8 engines, letting you check all 8 cylinders in under 15 minutes.

Compatible with all lab scopes—automotive or industrial—the WyzeProbe gives you a safe and simple way to capture secondary ignition waveforms without touching high-voltage circuits. Just bring the tip near the coil and start scoping.

Test lead sold separately, see below. See options below based on your scope’s input (BNC or Banana).

Test Lead
The WyzeProbe can be used with practically any oscilliscope. Select the the appropriate test lead to to connect the probe to your scope:
- for scopes with BNC inputs (Pico, OTC, Interro)
- for scopes with Banana inputs (Snap-on, UEI)

Key Features

• Scope All COP Cylinders Quickly
  Especially effective on Ford Triton-style V8s

• Works with All Lab Scopes
  Pico, Snap-on, Interro, UEI, etc. – as long as you have the right test lead

• No Battery Required
  Fully passive with internal capacitive protection

• Superimpose Secondary Waveforms

  • On COP coils: place near the coil

  • On HEI systems: place directly on the distributor cap

  • On conventional systems: near plug wires

• More Than Just Secondary Ignition

  • Alternator Diode Ripple: Touch the rear case—no need to reach output terminal

  • Fuel Injector On-Time: Spot mechanical injector issues, especially on COP engines

• Works on Most 2- and 3-Wire COPs
  (Some 3- or 4-wire coils may block signals due to internal shielding)

• Fully Shielded from Handle to Tip
  Minimizes electrical noise and interference

• Scope Faster Than Primary Side
  Catch misfires without scraping knuckles or unplugging coils
