Hmmm, top and bottom can be confusing. If the whole of the white wire is
external to the tach with the exception of passing through the pickup
itself, which is mounted on the back of the tach case, then whether it
passes through the top hole or the bottom first is immaterial. What *is*
important is the *direction* it goes through the holes. From what I can
tell from the diagrams in the manual, if you hold the tach in its normal
orientation the pickup is on the back. If you hold it such that the knurled
wheel is on the *right* of the two holes when looking at the back, the wire
comes from the switch, *down* though one hole, round to the left *away* from
the knurled screw, then *down* again through the other hole and from there
to the coil. It actually is shown going down through the hole furthest from
the tach case first and then through the closer hole, but as I say it is the
direction it goes through the holes that is important and not which hole
first.

Subject: Pos grnd tach/ wht wire
> I snipped the white wire going into and out of the tach with out seeing
which one came from where. The moss catalog on page 143 (on the next to most
recent version) shows the wire coming into the tach and then coming back
out. Now, one part of the loop is at the top and one is at the bottom. I
know the wire starts at the key switch and then goes through the tach and
ends up in the bay at the solenoid (I think, but that is moot right now).

top? I mean is the bottom of the loop the 'in' wire ( from the keyswitch) or
the 'out' wire (to the engine).
