JD 5300 not charging

[Digger1957]

First replaced battery then alternator.
When running the charging light flashes on & off every 20 seconds and still the battery isn't being charged.
Have checked all ground connections.
How do I check the relays? ohmn meter?
Any ideas? Cuz I out of them.

The service manual hasn't helped yet, still at a loss to why it's not charging.

You say the alternator has been replaced ... Check the voltage when the engine is running. Unless it's at least 14 volts, it's not charging.

The charging light flashes... Means the alternator is not charging when on. Is the flashing regular or variable ? A loose connection would be variable while a regular interval is some sort of protection circuit.... like a thermal cut out

The flashing is at regular intervals, about every 20 seconds constantly.
I'll check the voltage when running.
thanks

I wonder if the regulator might be separate from the alternator. If it is, they are prone to failure too, especially if there is high drain on the system like a hot wire arcing to frame or if exposed to very high heat. And, if it is an external regulator there should be a chart and instructions for proving its diodes.
