I found the problem using your information. Transformer secondary voltage with diodes
disconnected measured 88 volts AC with equal voltage of 44 volts between each leg and center. I decided to check the diodes again while I had them loose. One of them checked open the other good. The failed diode had a loose top post. I reconnected everything except the one bad diode and got the exact symptom, louder than normal AC hum and low output current of a few amps. Any idea what the specs or number of the diode is? I could not read the numbers due to corrosion. I will review the manual you sent for specs. This old charger will probably be around a few more years. Thanks again kgsc!
