Posted: Wed Apr 25, 2007 10:49 am Post subject: Mag Wiring

I didn’t get any verification on this so I thought I’d throw this out again…  

   

I'm sure this has been discussed but searching the archives didn't produce   

a lot, so I wanted to request a clarification.  

   

I'm wiring up two Slick mags with SPST switches. From the Z-13 diagram here's how I understand the mag wiring:  

   

   

1)      Use 18AWG shielded wire  

   

2)      Connect the mag-side ground pigtail to the ground stud on the mag.  

   

3)      For switch side, connect the ground pigtail to the ground side of t  

he switch, thus when the switch is closed, the mag grounds to the engine vi  

a the mag, using the shielding for the ground path and negating a parallel   

ground path.  

   

Do I have this correct?  

   

Thanks,

    22 works . . . most folks have lower limits for sizes

    of wires that run to the engine. It's a mechanical

    robustness thing. 20AWG would be a fine if you have it

    already.

    Yes . . .

    You've read the schematic correctly and this is

    what's recommended.
