Don't know what simple charger means.
Burned traces? Protection circuit?
Did it ever work with no battery connected?
Ok ill get some pics asap
By simple i meant just a regular 36v charger from online.
It has been working fine until i accidentally reversed polarity when connecting to a battery.
Yes now when i just plug the charger in without being connected to a battery, the fan runs constantly and getting 0Volts at the output connector
