Greetings -
I have a 1982 Ray-O-Vac 6/12 volt (switchable) battery charger and seems to work ??
Details
This charger is a 6-Amp charger with an ammeter on front panel....
The insides reveal a somewhat primitive design of a very larger transformer that switches out put of either 13-volts or 8-volts....has a rectifier, a large transparent glass fuse (with coil wire inside).
Input as written on panel state: 115vac 1.2 amps 60Hz 12vdc / 6vdc 6-amps.
Questions
I have no manual and have measured the voltages with a DMM and show a stable output of DC (don't have a scope though) but am not sure what it would do with a battery...
So I connected it to my JD 12-volt battery, connected up, plugged in, stood back and watched the ammeter....
It started at 6-amps and quickly and steadily moved down toward zero...(moving right -to- left). When it got to about 2 amps I pulled the plug and every thing seemed fine, all was cool to the touch etc.
Would you say this charger once it hits zero that the battery under charge is fully charged... ?
How would / could I check that ?
I have searched the internet and cannot find even a trace of this device, only when following the patent for the ammeter which has a patent can I find just the meter on line.
I don't want to ruin a battery, but seems in such good shape I hate to toss it... I like to refurbish / fix older electronics but wish I had a manual to work from....
Thoughts or suggestions / cautions are appreciated....
