No Spark on My Wife’s Honda CB400A – And It’s All My Fault

No Spark on My Wife’s Honda CB400A – And It’s All My Fault #vintagemotorcycle #motorcyclerewind #CB400 In this episode of Motorcycle Rewind, we dive deep into a no spark issue on a 1978 Honda CB400A Hondamatic. This vintage Honda automatic motorcycle was running great… until I took it for a ride. Now it won't start, won’t spark, and worst of all — it’s my wife’s motorcycle. We walk through a complete ignition system diagnosis, testing the ignition coils, pulse generator, CDI box (igniter unit), and battery voltage. If you're dealing with a classic Honda motorcycle with no spark, especially a CB400A, CB400T, or similar vintage twin, this video is for you. We also uncover a known stator issue on early production CB400As that may be the root of the problem. Follow along as we check resistance, chase down possible electrical gremlins, and pray that replacing the pulse generator/stator gets us back in the spark game. Whether you're restoring a vintage Honda motorcycle, troubleshooting ignition issues, or just here for the garage drama, this episode has a little bit of everything. 🔧 Topics covered: How to test ignition coils on a vintage Honda Diagnosing a no spark condition on a CB400A Common problems with the Honda Hondamatic ignition system How to test a CDI Tips for fixing no spark on vintage motorcycles 💥 Will I get spark before my marriage runs out of patience?
