Alternate electronic ignition systems, convient list of links

Some people have been asking about converting to electronic ignition. So here's some links I have book marked on electronic ignition using car and other moduals.

In past for my JB I had thought of using them and a Chevy Saturn coil (it is a waste spark coil, towers are in series.), but turned out my JB coil was good. Believe the Saturn coil has a ~ 1/2 ohm primary so may need a resistor in series with it to comply with min coil resistance your ignition modual may require (to limit max amps). Could use any waste spark coil , motorcycle or what ever. I just happened to have some Saturn coils, they have only 2 low-voltage terminals , the primary so easy to use.

1-st one seems most comprehensive, others are listed in no particular order.

IF you go with hi-energy coil it likely will draw more amps than original one. IF your Onan used a single fixed resistor for bat charging you may need to adjust it to maintain previous bat charging rate.

Do want to compare new amp draw to old. If it's a lot more might have to consider adding a 120V bat charger to provide (or supplement ) all bat charging and running loads. So you don't draw more amps from genhead charging winding than it's spec'ed for. I know after 1975 Chevys used hi-energy coils, and power supply wire to sparkcoil was MUCH fatter than on reg coils.

Depending on amp draw want to check amp rating of relays, switches, wires in circuit that supplies coil power.

Hey Len,

Just got done perusing the website on the top of your list. Besides lots of good advice, he's got dual tower ignition coils for $50 that look like you could use with Onan twins. Nice find.

from a discussion about a 30kw EK Onan today https://www.smokstak.com/forum/showthread.php?t=190910

Best thing you could do is get rid of the points distributor and install a Ford pointless distributor with their electronic ignition module. Get a much hotter spark and they are real dependable. We had them on the 300 ci Fords when I was at UPS and the mechanics even retro fitted the older package cars with points to the later electronic ignition and module. They also made the engine pretty waterproof when we drove in the rain and through puddles and some water crossings.
What year(s) of Ford vehicles should one look for to get the needed parts?
Ford, 1976 and later. ANYTHING with a 300ci 6 cyl, Vans, Pickups, and some cars. Chevy went to the HEI distributor in 1976.
Our Mechanic switched all the 292 and 250 Chevys over to the HEI ignition systems at UPS. Very few road calls due to ignition failure.

If my emergency/stand-by generator had a solid-state ignition system, and an OEM point-type ignition system was readily available I'd swap that system out in a heartbeat!
My opinion? Changing from points to transistors is a step backwards. :bonk:

Other than "early" transistor systems on some vehicles that were well known for failure: what electronic ignition systems do you deem unreliable vs. points and why?

I have a Magna Arc Electronic Ignition Kit sitting in a box for a 4BGE Onan and only because (and lack of time) it got new points before I found a NIB antique kit. Yes, I would keep points on hand in case the antique Magna Arc ever failed.

:wave: Today I don't have to go out and pump the gas twice and "hope" the car starts anymore. I turn the key and in a spin or two it lights off and running and does so for 100,000 miles without a "tune-up". Tune-Up being points adjustment or replacement for bad condensers, broken from fatigue wire, sticking, or burned up contacts. The timing doesn't even need to be set anymore.

As a side note most of my points experience is the "under flywheel" Briggs and Stratton small engines that take two special tools to get too. (Starter clutch wrench and flywheel puller.) A major PIA if you put new points in and the condenser is bad... I have had near ZERO trouble with their Magnetron electronic systems. Sometimes the spark plug out lives the engine: if it doesn't foul out. On the other hand their hard-starting non-float carbs were used way too long IMO.

I prefer to stick with the old stuff as well, I started up an old 1998 Jeep Grand Cherokee today, first start in 2 years.
A hot battery, and stale petrol - but it only runs on that for a few seconds and then switches to LPG. Just wouldn't catch. cleaned the rotor arm and dizzy cap electrodes and stuck in new spark plugs - lit up on the first turn of the key.
Suppose I should put fresh petrol in it now... happily Propane doesn't go stale and it still had a full tank!

I'll take a couple tomorrow, it's dark now - but I just remembered it's not old tech when it switches to LPG - I can plug in my laptop and change whatever I want, fuelling, max allowable revs, min allowable revs... I think you can even delay the spark or advance it if you want.
It self-programs when you first install the LPG kit, using feedback from the cat convertor sensors, but you can tune it whatever way you want.

That's the old girl in the dark - hasn't been washed in 2.5 years either and not a speck of rust on her. And Northern Ireland is WET, and I live in Bangor, a seaside town...
The guy I bought it from had it resprayed, the guy at the propane place I filled up at could never believe it was coming up on 20 years old. :D
It's an Orvis with the Up Country package, towing package, every bloody package you can imagine.
Black with black leather, we never got the daft ninja turtle Orvis over here, thankfully. :eek:

Just curious as to what kind of a Propane Fuel system it has in it? (Fuel tank & etc) We don't see Propane in Cars much here in the States.

It has a tiny petrol tank, and a large propane tank, both mounted under the back where the original petrol tank was. A firm over here actually manufacture the setup - https://tinleytech.co.uk/shop/petrol-tanks/35-ltr-combo-petrol-tank-for-grand-cherokee-zjzg-c3444/
- 7 gallons of petrol, which starts it up, then once there is enough heat in the coolant to warm the vaporiser up, it switches to gas automatically.
Brilliant little set-up given the price of petrol over here, and you then make your choice of "front end kit" which is the gas ECU and all that. All DIY installable if you feel confident that you can safely make gas connections. Plenty of stations have a fill-up point - in my old job, which was only 7 miles from home, it was perfect - there is a station half a mile away from home, one halfway along my commute, and one 200yds away from work!
If you look on Ebay for JGCs here, the majority of them are on LPG - most people can't handle the price of fuel at 18mpg and only putting out 190hp!

If there's a nuclear explosion close enough to me to render my electronic ignition useless, whether my generator will run or not is a moot point. Additionally, electronic ignitions are so cheap now that all you need to do is keep a spare on hand. EMP blows your ignition system? No problem, put the spare in and keep on keeping on.

There's a seller on eBay right now that going out of business that has massive amounts of Harley coils at dirt cheap prices. They're available in numerous ohm ratings. I just bought 4 3ohm coils for $28.99. 5ohm coils are about $10ea.
