When I went for a host home visit Gary left the charger out in the rain. And now it won’t turn on. All four fuses were ok. The output of the charger was zero. The charger is really expensive because of the voltage output being 35 volt at 20 amps. building it is really hard plus keeping it cool is not easy as well.
I believe that one of the two capacitors has leaked(because of the brown marks right by the vented Capacitor in the top board. The capacitors are 1000uf 50v
If it is possible to charge a battery that was originally used 20 amps with 5 amps instead please let me know
