Ignition Module
GA2928
Test notes: Modules with “BYPASS” and “Electronic Spark Timing (EST)” function - to observe the operation of these functions, connect the module according to the instructions and observe the spark in the spark gap. During the test, connect an extension of the red tip of the cable harness (RM02) to the "BYPASS" terminal and the spark must be interrupted. Then make a connection between the "REF" and "EST" terminals and the spark should bounce back on the spark gap. "TACH" terminal corresponds to tachometer output and should not be connected. Modules with three outputs - this module has three outputs, but only one can be tested at a time. To perform the test, connect the cables according to the instructions, but only connecting negative of coil C1 and perform the test. Then switch the green cable to C2 and perform the test again. Finally, connect the cable to C3 and perform the last test.
Signal type: Delco
