Cheap DIY Electronic Ignition

Here's what I've come up with so that I'm satisfied with it.

My only problem is that the housing makes contact with the pickup. Does anyone know if there's some sort of extended housing available?
Find a piece of steel big enough to mount the base on without the pointplate. Drill and tap the new plate for the iggy parts and maybe it'll fit under the housing.

i was trying to find that thread where they were messing with that chinese ignition to put it in, but couldn't. it's funny this hasn't been noticed in all these years. might need some small modifications to work with the xs, dunno. know where to get boards and moral support at least.
 
Since the pick-up contacts the housing, I decided to cut a hole in the housing and later I'll weld a little bubble over it. Its pretty ugly

^that's your kawasaki module? how's it going? does it expect to see a pickup and timing enough like an xs650?
 
Both boxes were made by Hitachi starting in 1980

XS 650 TCI Box TID12-01B
Duckster TID11-01A

Pickup coils are same impedance spec. Upgrading TCI dyno, hope to have it back in action tonight.
 
Sorta high-jacking my own thread.

Decided to give the GM coil a try. Its still a work in progress.
How did the coil work out. I've played with a similar GM coil from a coil pack and seem to work ok on the gonzo.

We owe @mrriggs , @pamcopete and bunch of other pioneers that took us down this trail.

Your pickup should work with the Gonzo and allow eliminating the advance unit.
I'm experimenting with a Chrysler reluctor and pickup that @kopcicle has some experience using.

I still have the CB750 coil actually. I haven't had time to install the GM coil because I've been in college but I plan to this spring/summer
 
Very nice update on the GM HEI concept.

The cool thing about the HEI module is the trigger circuit is very flexible.


As far as I know, a hall effect sensor isn't all that much different from an electric guitar pickup. Something passes over the magnetic field produced by the pickup, disrupting it, and sending a signal. Think of the reluctor as the guitar strings I guess (the thing that disrupts the field).

The guitar shares more in concept to the magnetic coil pickups that the TCI and the PMA crank timed cdi systems use.
Along those lines I have a 3 string cigar box pickup that I plan on testing.

A hall effect sensor is a solid state device that requires a supply voltage and is not particularly fond of heat, vibrations and I suspect a lower signaling voltage.

I'm not sure if your current pickup is a coil or a hall sensor

Will fit under the cover and should work with your reluctor.

I think for now I will stick with the current setup seeing as it has been working perfectly without any problems. I still want to give the GM coil a go though. If in the future, I want to experiment with a different setup the gonzo pickup you mentioned seems like a really good alternative so thanks for the recommendation.

Also are hall effect sensors typically smaller than coils? If so then I would bet my current pick up is a just hall effect.

Reluctors are two wire with a wave form output.... generate their own power.
Hall effect's are three wire... one wire is power in. two wire output.... on-off
 
Before modifying the twin points system to a single points system, I hunted around the wrecking yards in SA for the goodies. Not to be, the parts cost a bomb, Wreckers are pretty greedy here! I wasn't about to pay lots of bucks for a system made of second hand parts. I have all the parts set aside for a hall effect setup, just haven't got around to it yet.
 
Next is a coil. I used one off of a 1981 cb750 and spare plug wires I had laying around for my truck.

Mr. Riggs used a coil that a vast majority of GM cars used. If you walk around a junkyard they can easily be spotted

I didn't understand the purpose of using this but his logic was "it's big, powerful, and common"

Here's a diagram for putting this all together

What coil is it exactly. I have a fried Boyer and need the low ohm GM coil
 
Not to bring this thread up again. But can anyone tell me. Am I completely deleting my original ignition module. Keeping my current Hall effect set up. And wiring in a HEI. If so I have a single wire pick up from xS charge. I have the OE stuff still. Will my single wire work. Or do I need switch to something 2 wire?
