Ignition System Descriptions

NOTE:
- The following section applies to Hermann engine analyzers, tests and connections for Bear DACE engine analyzers are similar, please refer to instruction manual supplied with the EI (distributor-less) test adapters.
- When diagnosing starting or warm up complaints, do not check engine at operating temperature, instead proceed according to specific complaint.

Connection Method
Set engine analyzer to cylinder 1, select primary or secondary and test each ignition circuit.
The primary and secondary ignition systems can be tested. The ignition coils are equipped with a mounting slot (Figure 2) for the kV (pickup) sensor. The primary pattern can be picked up using the primary adapter lead (Figure 3), or through a connection from the socket box to the ME-SFI engine control module.
