The generator is original 6 volt on a 26 engine and when You start up and bring it to a fast idle the amp meter shows no charge with or without load/lights on. Manuely holding the cutout closed does not speed up the process. after a few minutes it usually starts charging slowing coming up to about 9-10 amps charge with or without load. It seem's like the generator magnets may need to be reflashed every time the engine is started ?
I don't be knowing. Your ideas please.
Generator slow to start charging.

Re: Generator slow to start charging.
I don't think you have problem with the magnets of your generator.
I should first clean all the connections on the wires starting on the generator and going to the battery connection. Check also the ground connections.
Than connect a 12V 21W light bulb between the generator output (not the cutout output) and the ground. Start the engine and watch the lamp.
If the cutout is not shorted to the ground, the lamp should just light up. Disconnect the wire at the cutout terminal ( pay attention this wire is HOT) and watch the lamp. It should become very bright. If you have no light your generator need a clean up or a total overhaul.
If the lamp lights up, test with a voltmeter (analog) the tension on the out put. It should be higher as 7V. Your cutout closes at about 7V.
As it take some time to show a charge on your amp. meter I think your problem is dirt.
Good luck

Re: Generator slow to start charging.
Also that 10 amp charge is not good for the battery. I would recommend adjusting the third bust down to a nominal voltage ( I think some recommend 3 amps) or changing over to one of the Fun Projects voltage regulators. I've always use a voltage regulator so I'm no expert on cut outs.

Re: Generator slow to start charging.
Jim, it may also be a dirty commutator or brushes. After a few minutes running the dirt/oil may be cut through so that the brushes again make good contact. My barn find Henrietta took two days to begin to charge after 63 years of no running. She does not fail to start up now though, straight on with the job.

Re: Generator slow to start charging.
I think you will find that to be normal. When the car sets for a month or two without being driven the residual magnetism tends to diminish. If you run it for a minute or two it usually will show a charge. It has to charge for a few seconds to build up the magnetism after which it will run at the charge it was originally set.
