Hi Jim, and Listers,
OK, I'm getting 50:50 'refurb' and 'upgrade' advice! A question, though
- are the modern replacements polarity sensitive? Does it matter whether
I'm positive earth or negative earth? I don't think it should matter, as
both the field windings and armature windings will be reversed together,
so it should still go round the right way.
Also, I understand that the new motors have solenoids built in, and that
there are two ways these things may be supplied - one with separate
motor and solenoid connections, and the other where these are wired
together internally (and you drive them both from the original
solenoid). In the first case you lose dependence on the old solenoid,
but have more wiring changes. In the second case you leave all the
wiring intact, but of course are totally dependent on a (now largely
redundant) old solenoid.
Have I got this all about right?
A rider to all this: in Listers' experiences, do these all come ready to
bolt on, no drilling/tapping, no switching over of the pinion gear from
the old motor?
Thanks for all the advice on the List, as always much appreciated.
