It's been a while since I've been around! New job, new baby, new addition to the house... I've been busy!
Well, I've got a general question that is electronic, but not light related. I've got a NEW baby swing that takes 4 D batteries and I want to plug it in. Sounds straight forward, but a little background:
We had an old baby swing that I had converted from 3 D batteries to plug in using a universal adapter set at the correct polarity and 4.5 volts. Worked perfect for the first baby. When the second baby came I pulled it out of storage and plugged it in. It seemed very slow, like it wasn't getting enough juice so I measured the voltage... it was something like 3.5 volts. I cranked up the voltage on the universal adapter to 6 v. and everything was fine again... well it was for about 2 months and then one day it just died. I could hear the motor, but nothing was happening.
Well, long story short, I don't know if I killed the last one, but don't want to fry this new fancy one. Any suggestions on what I can / Should do to get this to work using my universal adapter and a multimeter?
Thanks in advance!
(BTW... love this new forum software WAY BETTER than the old one!)
