2023年11月26日 · Having mysterious ignition issues. MSD 7AL-3 bought new in Feb 2023 - ran great until the last race of the season, then started having problems in the top of 2nd gear - misses and stumbles similar to a rev limiter or a significant retard to timing. Once the problem starts, it persists at all...

Only thing odd was that COIL + had about 4V and COIL- had 12V if I recall correctly (IGN on, not cranking) Does that sound right?? The Green Diag LED is dark, as is the red Trouble LED.

2011年4月3日 · [Note: The MSD 7AL-3 will retard the ignition timing approximately 4° compared to other MSD Ignitions.] I dug this thread up because of researching the start retard issue (which I'm having, and seems like the solution is to just not use the function), but what is the relativity of the 4* statement in the instructions ?
