Please keep in mind that this is from an amateur and that it may be cheaper to replace the charger. This is for the educational benefit.
With no load on the charger, on the 12 v. setting, it holds a steady 15.2 v. DC indefinitely. When I attempt to charge a battery, the ammeter starts to pulse rapidly, 0 to 6.5amps after 90 seconds. The transformer reads 15.5 v. AC.
I am assuming that the two squares on the back panel are diodes(?). Are the diodes the likely problem? Can I replace them with a 25 amp bridge rectifier that I have left over? Thanks for the help.
Also, what is the downside of using high amp bridge rectifiers? They seem cheap enough that a high amperage would be safer.
