Solar panel problem
I have used small solar panels for 15 years to keep batteries charged when toys are not use. I bought two new panels to hook up to other toys (motorcycles). These are just 2.5 watts. They have a ...

I would check the voltage of the panels while in the sun. Watch your multimeter. It should indicate + and -.
Then check the battery. Both should be the same potential, such as reading +12 on the battery and solar panel. However if you read +12 on the battery and -12 on the solar panel, it would indicate it being hooked up backwards. Or you might be reading something like 8 volts in full sunshine. Indicating that you will need to wire more solar panels in series to get to something like 15 volts, so that voltage will flow into the battery, not away from it.
