re: "QUESTION:- OK, assuming you’re still reading, could the
problems within the switch translate to sparking and issues within
the pumps’ points? And thus cause them to wear out so quickly?"<br>
<br>
Given that the pumps are designed to operate intermittently, I'd say
no. Getting decent points seems to be a crapshoot these days; did
your points wear, or become pitted? I suspect, but can't prove, that
contemporary points use less tungsten--an expensive metal that, I
think, is a bit difficult to work--than older ones; perhaps just a
'veneer' on a cheaper metal.<br>

<div class="WordSection1">
<p class="MsoNormal">About a week ago I posted a query which was
to the effect, “How long might one expect a set of (proper
Burlen) points for an SU pump to last?” <o:p></o:p></p>
<p class="MsoNormal">“How long is a piece of string?”, I hear
you say.<o:p></o:p></p>
<p class="MsoNormal">So, the reason for the original query was
this:- Not withstanding that they were not Taiwanese and that
I reckon they were correctly installed, I think that they wore
out rather quickly despite both sets being protected by Burlen
supplied diodes.<o:p></o:p></p>
<p class="MsoNormal">Replacing the points seemed, at first
glance, to be harder than I remembered from previous times……I
could get both sets running on the bench. With four plus one
extra holes after “throw-over(?)”. But, once in the car, one
pump would only work for a while….totally haphazard.<o:p></o:p></p>
<p class="MsoNormal">Eventually I turned to the wiring and
terminals at the “on, off, on” switch.:-<o:p></o:p></p>
<p class="MsoNormal">On….left hand half<o:p></o:p></p>
<p class="MsoNormal">Off….neither half<o:p></o:p></p>
<p class="MsoNormal">On….right hand half<o:p></o:p></p>
<p class="MsoNormal">The RHS terminals were intermittent. Ie
losing continuity hence cutting off power to the RHS.<o:p></o:p></p>
<p class="MsoNormal">QUESTION:- OK, assuming you’re still
reading, could the problems within the switch translate to
sparking and issues within the pumps’ points? And thus cause
them to wear out so quickly?<o:p></o:p></p>
