Ignition accessories

Additional pack of 4 short secondary ignition leads for the Mixmaster.

This kit includes four TA037 HT extension leads for measuring secondary ignition. This enables the user to test all four coils on a typical 4-coil cartridge pack.

In addition, the kit include a TA205 maxi fuse extension for measuring current in high current circuits, all supplied in a protective Pico foam tray.

Foam tray for your PP400 HT extension lead set, and two additional spaces for breakout leads.

HT extension leads are the simple accessory that allow you to take accurate secondary ignition measurements on COP ignition systems.

HT extension leads are designed to aid diagnostics on secondary ignition circuits by allowing an HT measurement to be made when there is no, or limited, access to any spark plug leads. The leads are specifically designed for use with the PP178 Secondary Ignition Pickup.

HT extension leads are easy to use: simply fit them between the coil pack and the plugs, place a capacitive secondary ignition pickup on each lead, and your scope will show accurate ignition waveforms with correct kV measurements.

HT extension leads are designed for use with PicoScope automotive scopes, but can also be used on all other labscopes that are capable of displaying ignition patterns.

3 metre (9 ft 10 in) BNC socket to BNC socket cable with earth clamp for use with the Coil-On-Plug Ignition Probe (PP338).

The TA204 coil-on-plug (COP) and signal probe from Pico Technology is the fastest way to check coil-on-plug ignition coils and spark plugs.

  • Find misfires fast
  • Displays scope patterns of the secondary, faster than scoping the primary
  • Works on all automotive scopes capable of displaying ignition patterns
  • Can also be used to investigate injectors and other inductive actuators
  • Flexible design allows for easier access to hard-to-reach components
  • No batteries required

Like distributors, spark plug wires are starting to disappear from cars. With the new COP ignition systems the ignition coils are connected directly to the spark plugs — eliminating the need for the spark plug wires. With no high-voltage spark wires, a COP probe is required to be able to pick up the secondary ignition waveform.

The COP probe comes complete with the TA033 BNC to BNC cable in order to connect to your automotive scope.

Due to the high voltages involved in secondary ignition systems, it is not possible to make measurements by direct connection. Attempting to make a direct connection will almost certainly damage the measuring instrument.

The MI074 is a capacitive pickup that simply connects around the insulation of an ignition circuit component such as a plug wire. This avoids the need for direct connection.

The MI074 comes with a shielded 1.8 m (6 foot) lead. It is suitable for use with conventional ignition systems and most HEI and DIS systems. Our library of Automotive Waveforms contains example waveforms captured using a PicoScope automotive oscilloscope and the MI074.

Although ideal for use with a PicoScope automotive oscilloscope, the MI074 pickup can also be used with most other makes of oscilloscope provided they have an waveform invert option.

With the Mixmaster 12-channel automotive signal mixer you can view an ignition parade display of up to 12 cylinders on any lab scope.

Mixmaster can produce a parade display of up to 12 cylinders using a single channel of your lab scope. If you have a two-channel scope, then Mixmaster can also display 2 engine banks separately with up to 6 cylinders per bank.

Mixmaster includes a trigger output, derived from one of the 12 input signals, which can be used to synchronize the scope to a known cylinder. Additionally, Mixmaster features a simple switch so you can invert a bank of signals to deal with negative-going signals on wasted-spark systems.

Designed for use with the Automotive Oscilloscope Kit, Mixmaster can also be used on virtually any other lab scope, and can be used on both DIS and distributor ignition systems.

Mixmaster is battery powered and includes a low-battery indicator. The shockproof rubber case makes Mixmaster suitable for heavy-duty workshop use and incorporates a handy stand to make it easier to use.

Mixmaster is supplied with three BNC leads to connect to the oscilloscope, an engine-block ground lead, and a set of 4 short secondary ignition leads. Additional packs of secondary ignition leads can be purchased separately.

Mixmaster is a cost-effective way to display parade ignition waveforms on your lab scope. Compact and battery powered, it is ideal for mobile automotive diagnostics, and makes a valuable and inexpensive addition to your tool kit.
