Terminal Designations (Excerpts from DIN Standard 72 552) The terminal designations do not identify the conductors, because device with different terminal designations can be connected at the two ends of each conductor. If the number of terminal designations is not sufficient (multiple-contact connections), the terminals are consecutively numbered using numbers or letters whose representations of specific functions are not standardized.

 

Terminal Definition

Ignition distributor with two separate electrical circuits
1a to ignition contact breaker I
1b to ignition contact breaker II
2 short-circuit terminal (magneto ignition)
4 Ignition coil, ignition distributor, high voltage
Ignition distributor with two separate electrical circuits
4a from ignition coil I, terminal 4
4b from ignition coil II, terminal 4
