Sounds like your battery is dead. If the battery itself is only showing 12
volts it is not properly charged, it should be significantly higher than
that (somewhere in the 12.4 volt range) and if the buss is showing only 10
volts with minimal loads the battery is dead.
Try substituting a fully charged known good battery just as a test and
probably all will be well. (Assuming everything used to work properly.) A
battery which has been discharged as low as 5.6 volts may not recover.
Discharging a battery that far can sometimes be a death sentence for the
battery.
I just went to the garage and measured a battery which has been sitting
unused and uncharged for about 18 months and it still measures 12.18 volts
so if your freshly charged battery is only 12 volts it has serious issues.

That was my first thought, but I would think a samll motor drawing 0.5 amps would still come on with some life. I thought I would inquire first before buying a 25 dollar garden tractor battery. If that works then I will upgrade to the 90 dollar PC680. I did not see any problem with melted wires that supply ground at forest of tabs. A grounding fault was another thought.

Unless you are in the market for a tractor battery, could you not just
run jumper cables from your car?

Rather than buying a battery for just testing either borrow one or simply
use your car battery (with jumper cables if necessary) for a test.

Just a coincidence, but I need to replace my trolling motor battery. Amazing how cheap lead acid batteries have become. Carries Exide name but suspect maybe 3rd world, although we do have a battery plant for various labels includeing exide about 60 miles from here (65 dollars 12v deep cycle)

I wonder if the real reason lead acid batteries have become cheaper is because they aren't using virgin lead. Recycling lead makes a lot of sense, but I've read that recycled lead makes for not only cheaper but also inferior batteries - inferior meaning shorter battery life. Does anyone on this list have actual statistical or analytic data/knowledge that suggests recycled lead makes for shorter battery lives?
Thanks.

If you price aircraft batteries or name brand car batteries, the prices
have about doubled in the last 5-6 yrs. 12V aircraft battery used to be
a little over $100, now most are over $200. And Absorbed Glass Mat
sealed batteries are now a little cheaper than the old wet acid batteries.
