Electronic Ignition (EI) System (Distributor-Less)




NOTE:
- The following information 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 individual ignition circuits on each coil must be tested one after the other (ignition circuit a then ignition circuit b). The ignition coils are equipped with a mounting slot for the kV (pickup C) sensor. The primary pattern can be picked up using the primary adapter lead (D), or through a connection from the socket box to the ME-SFI engine control module.

Air filter Remove, install

Ignition coil covers on top of valve covers Remove, install

Primary side connections:
Disconnect engine harness from selected ignition
coil (T1/1 - T1/6 or T1/1 - T1/8) and install
primary adapter cable (A) in between selected
ignition coil (T1) and engine harness Connect, disconnect

Primary leads with yellow (a) and green (b) connectors
(from primary adapter cable) to primary leads
on engine analyzer Connect, disconnect

Secondary side connections:
Kilovolt (pickup) sensor (C) to selected ignition
coil (T1) mounting slot Connect, disconnect

Kilovolt clamp connector from engine analyzer
(Note: kV clamp must first be removed) to secondary
adapter cable connector (d [3 pole]) Connect, disconnect

Secondary adapter cable connector (1- pole)
to kV (pickup) sensor connector Connect, disconnect


Figure 1 - Connection Diagram, Elec. Ignition System:






The individual ignition circuits on each coil must be tested one after the other (ignition circuit a then ignition circuit b).

Connect green connector of the motor tester to either the yellow or green socket on the adapter cable (dependant on which ignition circuit is to be tested)

Connect yellow connector (Term. 15) of the motor tester to battery positive (Terminal 30/15).
