[Healeys] Fuel pump points

[simon.lachlan at alexarevel.plus.com]

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?" 

"How long is a piece of string?", I hear you say.

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.

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.

Eventually I turned to the wiring and terminals at the "on, off, on"
switch.:-

On..left hand half

Off..neither half

On..right hand half

The RHS terminals were intermittent. Ie losing continuity hence cutting off
power to the RHS.

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?

Thanks,

Simon
