Thanks again to all who replied. Sorry for the verboseness here.... I had checked the terminals, grounds, cables, etc. (learned about this part from the Datto!). When the battery showed fully charged

You can also do a poor mans load test using the headlights. While measuring battery voltage, just leave the headlights on for maybe a minute. Then turn them off and wait 30 seconds or so. If you're n
