Msd 7al 3

Wisman Racing · 09-09-2013, 06:38 PM

Hey guys, I'm running out of ideas. The retard timing terminals on my box are getting energized as soon as I turn the Ignition on. The terminals are reading 8 volts to ground as soon as I put 12 Volts to IGN. I put a friends box in and it does the same thing. \
If I bench test it. I read 381K Ohms between Ign and all the retard terminals with no wires connected. The 8 Volts is enough to activate the timing if I put a pill in. I have checked grounds and wiring.
Any Input is appreciated. Thanks.

Call me.
The AL3 is different than the others and requires the chips be in all the holes.

FJ is correct. ..If you don't use the retard feature ,you must put zero pills in all the sockets.
I also have the terminals grounded , ....MSD recommends this if there are no pills installed, but I do both in case a pill falls out.

These guys are correct, the 7AL-3 requires zero chips where no function is desired.
