NE SD
We bought a new solar charger to charge battery in our tender trailer. We have the leads from it hooked up to battery and this battery runs 12 volt pumps and the electric start gas engine. It’s been sitting for several sunny days so I figured the battery was charged fully but later today it did not have enough juice to start the little engine. How do I test voltage to make sure it’s working? Does it just put out 12 volts when sun is shining?
