What do I need to gut the electrical system and put a dependable one in her? I saw a Sparx electronic inginition, with coils, and a wiring harness, but is this all I need? I would like to maybe even go so far as to put a halogen in the front of her. I want her to be dependable, well more dependable than a 40 plus year old bike lol.

Whatever works on a Commando will do the job on an Atlas. A good alternator, a Podtronics rectifier / regulator, change to negative ground and use LED lights and a good electronic ignition (Pazon works well, but there are others).

Not necessarily so when it comes to the ignition, if it's a magneto.

You can always go to a Commando timing cover & can, and run modern stuff. I'm sure I've also seen magneto adapters for certain EI systems...

Lucas 12V encapsulated alternator and magneto was and is pretty dependable.

Strip the wireing out of a Hillman Hunter or other pre 74 pommy car . Correct colour codeing. Mk 4 zepher has enough wireing for a space ship . Mostly youl find its all the same stuff and compatible.Normally , being ' indoors ' its mint.
Engine bay stuffs 50/50 . sometimes excellent , sometimes shot.from heat and oil .

These things have millions of connectors and sheaths of various types .

If you have a ‘’ maybe even go so far as to put a halogen in the front’ you should stick to a magneto and keep all the alternator output for the lights. You can now get a 120 whatt output alternator, but technically this will only put out 75% of continuous power.
