electronic ignition prob.

[paulwall]

Hi all have just bought a pertronix ..MR-LS1 for my duel points 77 spider.the guy said it would function ok.and easy to fit..The instructions are as clear as mud to me..elect not my best subject..can any one help with a simple wire digram or instructions...there are 2 silver canisters on the side of my distributor with black wires are these resistors.? please can any one help...all the best ..paul .ps i live in spain .

Those are condensors

It looks like the unit has one red wire and one black wire. Check the directions, but I would guess the red wire goes to the positive terminal of the coil, and the black wire goes to the negative side of the coil.

[paulwall]

yes i have done that but nothing..what happens to the existing wires in the dist. and do i keep the points or not.? and do i need the condensers.? thanks for the reply..paul

Seems pretty clear to me.

1. Turn the ignition switch off or disconnect the battery.
2. Remove the distributor cap and rotor. Do not disconnect the spark plug
wires.
3. Examine the cap and rotor for wear or damage. Replace as needed.
4. Remove the points, condenser, and grommet. (In this case you have two sets of points and two metal cans that are the condensors. They are about 2" long and 3/4" in diameter.)
5. The Ignitor does not require any modification to the distributor. Therefore
the points, condenser and hardware can be used as backup. (So put them in a bag and keep them in the trunk)
6. Clean any oil or dirt from the breaker plate and point cam.
7. Install the Ignitor plate onto the breaker plate, and fasten Ignitor plate in
place.
8. If the distributor ground wire was removed during the installation process,
be sure to re-attach it securely.
9. Install the magnet sleeve over distributor shaft and onto the point cam.
Rotate sleeve until a slight locating position is felt before applying
pressure. With sleeve lined up on point cam, press down firmly insuring
the sleeve is fully seated.
10. Insert both wires through the hole in the distributor housing. Pull the
grommet into place. Make sure that the wires do not interfere with any
moving parts.
11. Replace the rotor and distributor cap. Make sure that all spark plug wires
are attached securely.
12. Connect the Ignitor black wire to the negative (-) side of the ignition coil.
13. Connect the Ignitor red wire to the positive (+) side of the ignition coil.
14. Reconnect the battery and make sure all wires are connected correctly.
15. The engine can now be started. Let the engine run for a few minutes and
then set the timing in the conventional manner.

thanks for the set of instructions.What is the magnetic sleeve..? I did not get any thing like a sleeve in my box of bits.All that was in the box the igniter,rubber grommett,plastic tie,4 screws,and a mounting plate....paul

[RoyBatty]

The magnetic sleeve should slide over the cam that opens your contact breakers (points)
This sleeve has the magnets that work to trigger the hall sensor in the electronic module.

If you did not get the sleeve than your kit was incomplete.
It sounds as though you were missing instructions also.
You can see the sleeve in this picture at the far right.

hi roy. have email supplyer he says i dont need a sleeve.? unless my cam lobes are worn,he also said to check if it is geting 12.5 volts..will try thursday..thanks...paul

[RoyBatty]

Yup, verified with a call the their tech support line.
Instead of a magnetic sleeve, they just use the lobes of the distributor cam as the interrupters.
As the high point of the cam comes past the hall sensor, it triggers the module to fire.
There is usually an air gap setting for such devices to tell you the best clearance for the device to work properly.
This gap would be measured between the high point of the cam and the sensor.
Maybe that gap is predetermined by the plate they supply in the kit.

thanks roy will try again saturday..paul
