Welcome Paul on FF-Forum.
Here some solution why battery is not charging:
Solution #1: Focus on your battery first. If your vehicle has stopped running, jumpstart the engine, remove the jumper cables as quickly as possible, and wait. If the vehicle keeps running after a period of time, there’s likely a problem with your battery. Take into account the outward appearance and age of the battery when deciding whether to replace it. Also, inspect your battery cables and make sure they are in good shape. Bad cables will not deliver the full current flow needed to operate properly.

1. Crank over the engine, turn on your vehicle’s lights, and observe. If they start bright and then slowly fade, your alternator might not be delivering the proper charge to operate your vehicle accessories.
2. If your vehicle is already dead, jumpstart the battery and wait. If the alternator is bad, your car or truck will eventually die out again as the battery is not re-charged.
3. Get a good-quality voltmeter or multimeter and test your battery’s state of charge. The voltmeter should read around 12.6 volts with the engine off and 14-15 volts when the engine is running. If voltage is below 13.5, there’s a good chance the alternator is not keeping up with your battery’s charging needs.

Solution #3: Check the alternator cables for abnormal wear, including cracking and fraying. Replace or tighten the cables as necessary.

 

There have been problems with the plug that plugs onto the alt. The inner contacts don't make good connections and can send you on a wild goose chase . Make sure they are clean and tight.

 

Great post hanky. Agreed with you, you have to clean all things and tight !!
