NI-CD fast charger

[Jim]

I have an Associated Electronics NI-CD fast charger model 3772. It has
"lamp cord" input and output wires, a Rhodes 30 minute timer on the
right side, an 8-0-8 ammeter on the left side, and a 3 position slide
switch in the middle, which is marked "discharge" at the bottom and
"charge-4 or 6 cells-5 and 7.5 volts I assume. It has a pair of 22
watt .75 ohm resistors underneath, one of which burned out. Does anyone
have any info on this unit (input voltage, etc.)? Thanks, Jim

Yeah, don't use it. These ancient fast chargers are dangerous to the
health of your nicads. Find something more modern that has an intelligent
charge controller.
