Ignition by Sebring

Anyone heard of this ignition system. It uses magnet pickups on the alternator rotor and a control box that doubles as a rectifier and regulator. My new combat is setup batteryless with this, and it still all works after sitting since 83. And as a bonus the points and AAU are still in there, not hooked up, but not missing.

Hi,
They are made in Oregon by Sebring electronics corp., they give two phone numbers in area code 503 first is 479-7565 and the second is 479-9696. On the British only website www.britishonly.com they give a very complete description + mounting instructions ETC.. They are relatively inexpensive at about $130usd.

Hi again,

I bet those aren't made anymore. I'd like to be proven wrong. :mrgreen:

I'd be checking that rotor to see if it is loose on the hub. Those black streaks are usually a warning sign.

That doesn't look like a Lucas rotor?

------------------
Tim, what you're seeing isn't the end of the rotor but the pick-up disc that comes with the system,

Brent,

I' d like to know which coil is used on that bike and what kind of ignition switch, because it's a CDI unit which means that the ignition switch and/or kill switch will receive around 200 V AC. I don't think the original ignition switch and kill swith are up to it.

bwolfie · Jun 19, 2011

the coil looks like a japaneese dual output denso, and the switch is a hardware store toggle switch. I was lucky as the PO removed the factory harness, which I have, and installed bare bones wiring.

Does anyone know if they are still available?

And how well does it start without a battery? Do you have to kick like hell to spin up enough alternator current??

Hi there, is someone had any feedback about those ignition kits for our commando:

I would always be a bit wary of any alternator only fed ignition systems. Back in the mid 60's I had a Triumph Tiger 100A, this used what was called Energy Transfer (ET) ignition whereby the coil was powered directly from the alternator. Absolutely useless, I re-wired it to normal coil ignition and everything was fine. Admittedly we only had 6 volt alternators at that time but it really was a useless system, such unreliable starting.
BTW, I have Boyer Mk3 on my 850, been on there since the late 70's with no problems at all,

I ran one of these on my race bike for a while back in the '70s. It worked ok, and started fine without the battery, but with the Lucas blue can capacitor. Eventually, the steel pins moved enough to wear the holes they were in to a pretty loose fit, but the magnet held them in well enough that they didn't come out. The pickup was trashed when I broke a primary chain, and I went to a different ignition system. It was fairly easy to start, because it used two pins to trigger the spark, a taller one that triggered it at kick start speeds, and a shorter one that didn't generate enough trigger current until the engine was running, giving the full advance.
