question

The GM LS1 coils have four contacts. One is 12 volts. One is signal
ground. One is ground. The fourth wire is from the computer and is a 5
volt positive pulse. The coil fire after a dwell delay of about 5 ms.
How does a DIS system convert this coil into an MSD coil? Does it switch
the 12 volt contact off and on? Paul Lamar


Dear Sir:


The DIS won't convert the signal. The LS coils are a stock coils and
CANNOT be used with an MSD DIS controller.


Thanks,
