SABER Charger NTN4734B
Posted: Sun Feb 15, 2015 1:17 pm
1) I just bought what appears to be a new old stock 1989 vintage NTN4734B charger to give my NTN4734A a break. I noticed a few things different off the bat.
1) The STANDBY LED in the upper right corner is more orange/green than the Yellow of the "A" version? Weird.
2) The contacts seem to be particular tight, especially the outermost two. Sometimes the battery does not appear to make contact.
3) On some batteries the STANDBY LED Flashes and then the red CHARGE LED blinks and all lights go off.
4) These batteries all charge properly in my A version charger.
5) What are the differences A versus B?
6) Where can I find a schematic?
Thoughts
Thanks
