Lotus Elan and Lotus Elan Plus 2 Forums

Hi Listers,
After 4 years of hard work, my +2 is nearly ready to have the ignition
keys turned to see what happens.
I fitted a number of years ago an Aldon Ignitor, with a red and a black
lead. Somewhere in my garage I have the fitting instructions, but for
the life of me I can't find them.
Does anyone know where the red and black wires connect to on the coil??
Also what colour wire is fitted to the oil pressure switch?
I have a 72/73 +2S 130 / 5.
(I have a workshop manual, and as is with Lotus every circuit diagram is
different!)
Kind regards
Jeff ( nearly there!!!)

Hi Jeff
Connect the Ignitor BLACK wire to the NEGATIVE terminal
of the coil and the RED wire to the POSITIVE terminal. For
installations that use a primary ballast resistor, it is
preferable to connect the red wire to the ignittion switch
side ot the resistor side rather than the positive terminal of
coil.The wire to the oil pressure switch is black on my 1969 S4.

Regards
Petter

After 4 years off the road, having rebuilt the engine and suspension, I
turned the TC over tonight.
It was a bit tight to start with, but eventually was spinning over OK.
I had fitted an Aldon ignitor four years ago, and I wondered if you
could test it statically as you could with the old points and a bulb.
It looks like I have no sparks at the plugs, as my strobe lightdoes not
even flicker.
I'm pretty sure that I have wired it all back in correctly, but then it
was four years ago when it all came out!
It is quite frustrating as I really want to get the old girl back on the
road before the winter really sets in ( or the price of petrol gets to
?5 a gallon, whatevers sooner!)
I trawled the archives and noticed one posting suggesting thet the
magnet can wear the rotor an short the ignition.
Are the Aldon ignitors reliable?
Any help greatfully recieved.

The first thing I would do, key on in run position take a test light to the
+ side of the coil and check for light. If that is good then with the
starter engaged move the light to the - side and see if it is pulsing to
trigger the coil. If you don't have a light on the + side go to the
connection on the tach as the voltage is feed from the switch to the tach
pickup and then to the coil.
You can run a test wire from the battery side of the starter switch to the +
side of the coil, which is hot wiring and it should fire right up if the
ignitor and coil are good.
I have also had the high voltage lead out of the coil pull up and not make
good connection.
Been thru this exercise many times and usually find it to be the connections
at the tach being loose and pull them off and recrimp them with a plyers,
push them back on and off we go!
Good Luck
