Fitting a Dyna S ignition system - with pictures
Posted: Wed Sep 12, 2007 5:26 pm
As per request here is a photo guide to installing a dyna s ignition system. It assumes you have the instructions provided with the dyna system. If you don't this will not help too much.
Firstly here are some shots of the points ignition system. These were taken in case I had to revert back to points.
Next is the the wiring which goes from the points to the coils - these are the two wires you are going to remove/disconnect when you remove the points plate.
Remove the points plate and the wires. Place is a box.
Remove the advance/retard unit - remove the points cam from it and replace it with the black trigger cam provided with the dyna system. Note this has to go on with the 1/4 makings to the top and the magnet (in the black trigger cam) to the left.
Reinstall the advance/retard unit.
Mount the new timing plate and feed the wires through to where you disconnected the points wires from. It is long enough (just).
Connect the wires as shown - note mine has a white wire with a black sleeve and a black wire with a green sleeve. Use the sleeves as indicators as to where to connect to.
Crimplock the dual red wires to the red/yellow wire shown - this is the 12v power wire and give power to the triggers.
Now to timing. You can follow the instructions in the manual and as provided in other threads or you can do it the way I did it. I take no responsibility for my way but it does assume you have a strobe timing light - if not follow the published procedure.
Timing
I had removed all the plugs from the engine and but had the plugs in the plug caps. slowly rotate the engine until the no 4 plug sparks. Note where the timing mark on the case is in relation to the F 1/4 mark on the advance retard unit. Adjust and repeat as necessary until they line up as the plug sparks.
I then put some tippex on the fully advance mark - about 1/2 inch to the right of the F mark. See photo.
Connect everything up and it will (should) run. warm up and using a strobe check timing at over 2,500rpm. if the white tippex mark lines up you're done. If not adjust until it is.
My now starts better, runs better and idles nicely at 800rpm - never did before.
Thanks to Mr Saunders for prompt delivery of the above bit of kit.
I await all the corrections...............

to stop voltage irregularities (or sumink)
