It's a well focused pre-Quadra tome with a copyright date of 1992 and updates through 1995 from M&T Books. It harks from the era when "Hackintosh" meant a hardware hacking tour de force as opposed to a mere rogue installation of CatWare.

. . . locate the the contacts of the RF choke filter and check for continuity from side to side. If you detect an open circuit, that means the RF choke filter must be replaced or temporarily bypassed with a jumper wir . . .
Belay that! He further adds:

I usually wire a 1-amp pico fuse across the open circuit (I put a turn or two in the lead). Pico fuses are less than a dollar and are easier to install than an RF choke filter that costs a few dollars (if you can find them). It's also safer than running a straight piece of wire (which would be like putting a penny in hour home fuse box).
That sounds like it may do the trick for your SE now that you've mentioned the location of your 5V continuity failure.

I've never seen the The Dead Mac Scrolls, what's the MacTimeLine coverage of that one?

I think this one is is right smack in the middle of the gottahaveit! category. It has a 36 page chapter on testing utilities, tools and safety including an explanation of how to use and what kind of logic probes necessary for pre IIfx & IIfx/Quadra era Macs.
