My new Trojans don’t seem to be charging. It will show full charge but will die after going less than 1/4 mile. Any suggestions or anyone that can help?
Did you change from FLAs to gel or vice versa?
Begin by putting it back on the charger. When it says that it is done charging, test the voltage of each battery and then at the controller. Post the results here and people will dig into the information provided to try and diagnose the issue.
