Roland,
I doubt you'll solve this with keyboard mechanicing.
You need a meter that tells you the SOH (State Of Health) of your battery.
The old Milton rapid-discharge meters are obsolete now.
You need to recharge slowly with a new fangled charger that won't fry the battery like the old big 20 amp chargers would.
The new chargers also have a maintainer and de-sulphate function . So they are way more useful and effective at reviving a battery and keeping it in good shape.
The $5 Trickle Charger your Grandpa uses is not a good idea anymore!
Then you need a different meter and a fuse diagram to track down the 'dark current'a.k.a "Parasitic Loss" ,or key-off draw.
If you understand the basics, have the equipment and the patience it is a rewarding mental challenge.
When you are done,suggest you add a polarised charging cable connected directly to the battery terminals (fused)that allows you to charge without opening the Frunk.Make sure the connectors are weather proof and Klutz proof.
Enjoy !
