[Mg-mmm] PA ignition switch

[Lew Palmer]

Neither one is correct, Sarah.

The PLC2 is the right model, however, the switch should have FOUR positions
and no window. The positions are "Low" or "Summer", "High" or "Winter",
"Side" and "Head". This assumes use of the original cutout/fusebox. F1 and
F2 positions lead to the cutout from whence these is a lead to the field
coil of the dynamo.

I hope this helps a bit.

Cheers,
Lew Palmer

I haven't seen a posting on this list in quite a while, so here's one to
break
the silence:

I'm sorting through the bits of PA0935 for the first time in 25+ years, and
need to know which (if either) of the the two ignition switches I have is
the
correct one.

Both are Lucas, and marked "PLC2" on the back.

#1 -- FP series key
        window shows "1  2  side"
        "Lucas" stamped into face
        7 wiring connectors on the back:  F2/D/F1  [top];  L/T/A/H  [bottom]

#2 -- MRN series key
        window shows "Off  Side  Head"
        "Lucas" printed on face
        4 connectors on the back:  A  [top]; L/T/H  [bottom]

Comparison with the wiring diagrams in the PA Instruction Manual and Philip
Smith's book show that #1 is more likely correct, though even that one isn't
a
perfect match (I don't see an "F2" in the Handbook diagram).  The #2 switch
reminds me of TC, though it doesn't match any of the diagrams in Smith.

Can anybody out there help?


Thanks in advance,
Sarah Carr
PA0935 in Penna.
