Pertronix 1741 & Coil Install

Post by raylim »

Steps to installing the Pertronix 1741 ignitor and their recommended 3-ohm coil.
~Enjoy!

Disconnect negative battery cable.

Rotate crank until Cylinder 1 is at TDC (Top Dead Center).

Remove Cap and inspect for cracks or abnormalities
IMG_8409.JPG
Proper alignment of rotor would be at 11:00

Note wires going to the coil (connection to positive and connection to negative)

Remove Rotor

Remove Points with the two screws

Install Pertronix ignitor with supplied screws (don't forget to reattach ground wire!)

Install the cover, align the notch over the wires and don't forget the rotor!

Install the Pertonix Coil Flame Thrower (3 Ohms)
IMG_8416.JPG
Connect the red wire from the ignitor to the positive terminal of the coil and connect the black wire to the negative terminal of the coil
IMG_8417.JPG
Connect the wires (for my 1970 the white/yellow & black/white to positive)
IMG_8423.JPG
Keep the wires (not being used) wrapped together in case you have to reattached them if the ignitor fails.

Make sure you save all your old parts and keep it with the car just in case the pertronix fail
IMG_8426.JPG
Install a wire loom wrap to keep wires tidy. Install Cap and coil wire.
IMG_8428(1).JPG
Turn vehicle on and set timing back to factory specs
IMG_8427.JPG
Coil can be mounted vertically (recommended to keep main windings cool from oil within the coil)

Or having the terminals at 9:00 and 3:00 position. This was the temp reading of my coil after running for 20 minutes.

Please let me know if I"m missing something. I hope this was comprehensive enough!

Ray,
Is it TDC on the compression stroke? I think so
And then might want to explain what and how to determine what compression stroke is....

Good job/document, Ray. Who did you buy the Pertronix and coil from, and how much? Thanks,

Spark timing for TDC is between the compression and power stroke.it is just when the cylinder is about to receive a spark when both valves are closed. You can find TDC by looking down into the cylinder with the plug removed and seeing the piston rising up while both valves are closed. This, of course, can be seen when the valve cover is removed and noting the pushrods bottoming into the head (in this situation as i have a pushrod engine).
On a side note, TDC can be also between the exhaust and intake stroke but here the exhaust is about to close and the intake valve is about to open. I hope this helps as i may be a bit rusty since my ase certs expired back in the late 1990's.

Good documentation.

Here's a past post with some links to Pertronix references that may be of interest to someone in the future.
