LT-A50 ignition system: How does it work?

I have been given an old Suzuki 50 quad, probably an LT-A50. It has the pull start mechanism missing and am wondering if this contains any igntion components? I can't find any points or electronic equivalent (PEI?) There is a coil beneath the flywheel and one wire which leads directly to the coil, which has branches off to a kill switch on the bars and another mounted at the rear of the I can't see any spare connectors where anything else would be wired in. Whats missing? Any one got a manual or diagram? Ideas?

Nothing is missing. Just go get that pull starter assy and bolt it on.

There are no points or sensor as you might expect. It uses a pulse coil and a cdi box to fire the plug.

Re: LT-A50 ignition system: How does it work?

Thanks for that. At least i know where my cdi isn't! All I can see is the single coil under the fywheel and an ignition coil bolted to the frame. So where is the CDI? The wire from the coil under the flywheel goes straight to the ign coil, with connectors off it going to the kill switches. I can't see where anything else would connect in or even be mounted. What's missing, what does it look like and where does it go? Am I being amazingly stupid or is what I take to be a simple ign coil is some bit of electrickery that controls the spark too? I get current from the primary coil but nothing from the ign coil but I assume that's cos there' s nothing to make and break the circuit and throw a spark. Help!!

Re: LT-A50 ignition system: How does it work?

the spark is controlled by the a/c wave changing on the pulse coil output. Look up a schematic on basic ignitions and you will see what I mean.
