Lotus Elan

I am pointless! Possible Pertronix problem..

PostPost by: Tim Moore » Sat Oct 30, 2004 1:13 am

I have the Pertronix ignitor in my 1970 Elan S4 Se,, beware of this problemin the future. My car leaks major oil ( I have a new Rubber , oil down tube to install in the spring),, It has oil everywhere.. 1 Day as I was driving after a 26 mile round trip , The car started to run on only 2 cylinders. After 3 hours of trouble shooting and new plugs, We found the problem was the Black, round, Plastic Pertronix part with the 4 magnets.. Oil had seeped in the unit, as it is not sealed, and covered 2 magnets..
After we cleaned it well, we put the magnets back in. CAUTION, to avoid major hours of work, (DONT DO WHAT WE DID)...take only 1 out at a time, clean, and replace in the SAME position as it came out..You MUST put a plastic spacer in the unit, as the magnetic pull will make all 4 pop out and stick together..We found later, after 40 combinations of magnet fitting, that they are ALL Polarized and can only go in 1 way...
I intend to seal the round black unit with superglue this spring, so the unit will be water and oil proof...It is now working fine.. Tim Moore USA

I've just replaced the points and condenser in my Elan's distributor
with one of those popular Igniters.

Fitting is was easy.
The wiring is simplicity itself.
The components look well constructed and all the parts fit well.

I noticed one other thing. There is now more ignition scatter around
idle.
I half expected this. I had guessed beforehand that the heel of the
points set would cause some drag on the distributor and it looks like
this drag take some of the play out of the system.

Now, without the points, and at low rpm. there's more wobble going on.

Has anyone else notice this?

Now, I have two more questions.
Q1. Do you think that the advance curve will have changed in any way
with the removal of the points?
Q2. While the specs for the ignition timing are specified at idle, does
anyone on the list work from the other end?
i.e.. Does anyone set the ignition timing at e.g. .35deg. at 4000
rpm and ignore what advance that gives at idle?

In my experience its not the presence of oil that caused your problem as oil
will not have any effect on magnetic forces, although suspended (magnetic)
metal particles could eventually build to a thickness that would 'short out'
the magnetic field.

The moulded magnet housing on my ignitor separated into its two parts whilst
driving allowing the magnets to become displaced resulting in very poor
running.

I reassembled the two halves of the moulding and secured it with superglue
only to have the same thing happen again! The second time I rebuilt it I put
an excess of RTV silicone in the various mould cavities and let it extrude
out when I pressed the parts together.

Its never missed s beat since.
