If you ever tried to spot-weld two alu sheets, the welder developing
about 1 volt, it will show you that it is a question of voltage to break
through the oxide layer. After tat, you have conductivity. In order to
spot weld, scratch the surfaces hard with a rotating steel brush, after

Greetings to PCW;
I have a 2nd apparent failure of a 5i25, affecting the same p3-15 pin.
So I am suspecting I have a bad BoB or home rolled cable.
I have a perfectly good 4.77 volts at the BoB's input, which does go to
ground if I touch the wire to the machine frame, but it is not getting

I will also note the apparent conductivity of my anodized
solder-sucker. But that is probably a think anodised

No, really. Get some aluminium and your multimeter. You will find

I have never found aluminium to be non-conductive.
You could consider using one of these instead of a probe:

On the steering racks Ford used on the Pinto and Mustang II, the big ends of
the bellows/boots had the ID off center with a vent hole for a metal pipe
(around 1/4" ID) to push in so that air could flow back and forth as the rack
moved.
Whatever you do, it shouldn't require a really large vent

Greetings all;
I am about at that stage in this conversion where I am about to hang the
Z screw. I have some bellows to serve as debris shields around the
screw. So I'll need to make "nipples" to connect the bellows, at the
support bearings and at the traveler nut mount. Alu rod enough for
