[Healeys] "Engine making a weird noise"

[Per Schoerner]

Simon
The ignition needs some voltage to work properly. If the battery is flat, not only does it make the starter not working, it also makes the ignition not working.
Someone suggested disconnect the fan belt, start the engine with the help of a healthy battery. If the strange noise is gone then you can be assured that your generator have some bad bearings, and is not able to provide the current needed to feed the ignition.

That would be contrary to what I’d expect. Generators fail………the lights go dim but the engine, if it dies at all, does so unspasmodically? (If that’s even a word!). In my experience, it’s more a question of the battery being flat as a pancake when you next try to start the car.
