I was looking thru teggar's igniter (ignition module) test and noticed a contradiction in reference on this line, "The igniter... will only switch off when grounded, but not when Terminal 4 is floating." is contradicting with the service manual.
The service manual seems to imply that a ground short may damage the igniter, although Hondas are known as electronic ground safe vehicles, such that accidental grounding of circuits isn't likely to be harmful. Already, the ECU grounds terminal 4 to produce a spark so why bother. Ground or not, the question still stands. Should grounding terminal 4 on a standard 4 terminal igniter (ignition module) cause damage?
