So if anyone has all the bits I need...lmkVery little. As long as you got the complete set up, distributor, loom, coil, ballast resister and control box it would just use the wiring you already have. It’s basically a standalone system.
Have u installed yours yet ? Do you know for certain it fits a 1300 ?https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/262293985349
I bought one of these. Another fellow is running one so I thought why not try it. It was 40.00 with free shipping. View attachment 12147
Looking for a source or good used electronic ignition for my X. I cant seem to locate anything to convert my ducellier distributor to electronic. Mine is a 78 with the 32 datra carburetor. When I got the car it had a couple spark plugs wires missing and someone had removed the dizzy. I got #4 at tdc and put the dizzy in. The first time I had it running it ran very smooth with exception idle was higher than I liked. After I desmogged it,it started running a lil rough. I put in new plugs,checked gap. Checked gap on points. Partially disassembled the carb and clean it. It fired up and ran smooth except high idle again..the more i try to get the idle down and set the timing with a timing light..it has progressively gotten worse. I want to convert to electronic ignition just for reliability reasons. I would appreciate and guidance or help. So if anyone has anything to offer me please DM me with what you have to offer... thank you in advance.
Mike

Thank you..for your reply...I talked to Brayden and they dont have any in stock...that's why I'm considering this unit...cost is worth a tryFYI
I have a 78 1300. I swapped my original Ducellier for a used electronic unit and sender purchased from Midwest. I mounted the box in the spare tire compartment. I have had no issues it works fine and no more fooling around with points.
I have attached the circuit diagram, this should be self explanatory. The main component is the IGBT which is designed for electronic ignition. It is robust with lots of protection nevertheless the circuit I developed has added protection. You could simplify it if you wanted, the bits I would leave off, if I did this again, would be the LED indicator and the change over switch. The circuit has been reliable, I tested it before and after installation and have had no issues. I installed the circuit in a small die cast aluminium box from Maplin (The box was the most expensive item at £5.). Installation can be a problem in the X19 because it gets hot! I’ve found a couple of good places, but this time I installed it just behind the thermal insulation that lines the engine to passenger compartment bulkhead. Here it is close to the coil and distributor so no long wires. I estimate the cost of all components to be about £13.00, the components were from Maplin except for the IGBT which I purchased via ebay. The design is mine, but I am happy for you (and other X19 owners) to use/adapt at your risk....but Ive had no trouble at all. Let me know if you go down this route.
I would not recommend the Vellerman kit which is available, the components are not ideal as they get too hot. The kits with high voltage drivers and a hall effect switch to replace the points are perhaps the most logical but you might need to go to a specialist (like Powerspark Ignition in Bromsgrove) as the X19 is not common enough so they adapt another kit to fit the X19 distributor. I was not happy with this as I wanted something I could quickly revert to standard should the electronics fail.
That circuit shown uses an IGBT to carry the current that the points would normally carry so the points only carry a low current. I've used several capacitive discharge units with the 1974 Ducelier distributor and the points never wore out. I'd expect the same from the circuit shown. With a CD unit, dwell angle is not important (unlike the circuit shown) since the coil is only used as a transformer and not to induce a high voltage in the secondary when the points open (V=L*di/dt) as in the stock Kettering type system. A CD unit typically gives a much better spark for starting and at high rpm.I did find this a while back and want to try it someday. I have a hard time fully understanding it, but care it to using relay's on high power items. From what I've read, points have a short lifespan due to the wear of the excessive mass of electrons passing. This just uses the points as a signal instead of the actual load. That's my understanding.

Quote from link above:
Once I get my car back on the road, I plan to see if I can adapt a 79 pointless distributor to a CD unit since I don't have the interface box that goes with it.
Yeah, I saw the GM module info but if I can interface one of the CD units I have it should provide a better spark. The GM unit uses the coil just as the points do as a Kettering type ignition.You don’t need the brain the ignition came with, you can use Bob Brown’s guide on adapting the GM ignition module to do the same job.

CD is short for capacitive discharge. I can tell you how they worked about 30 years ago, but I have not investigated them for quite a while. I know MSD was a major supplier. I actually designed and built one for a senior thesis. Basically, you have a ~400V power supply that charges a capacitor that is discharged through the coil at the proper time. Fancy units can do multiple discharges during a single combustion event to provide more thorough burning. A major advantage is they can maintain the same level of spark at high rpms. They can also provide a good spark at low battery voltages if properly designed so they work well for cold weather starts.Random question... whats a CD unit? dllubin, you obviously sound smarter than I am.
Ps. ha a Capt'n Obvious commercial came on just as I was typing "you obviously sound smarter than I am." Excellent timing!
Well....I pulled the trigger and just now bought this one...be here end of week....so hopefully I'll have it installed next week...if it doesn't work for my application,I'll post it up for sale here...fingers crossedhttps://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/262293985349

What year is his X ?...is he on this forum ? I got mine today ...hope to have it in early next week.https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/262293985349
