From the Atomic 3000 manual: "The MAX-15 model will in theory accept AC power from 125 to 250 volts, but for optimum light output we only approve use with power rated from 200 to 240 volts nominal." There is no mention of changing the PL113 jumper, which IMHO implies that the jumper should...

So strange. What device are you using to measure these voltages? Is its signal ground possibly connected to earth ground?

Hmm, something is way off. If you are plugged into 120V mains, you should be getting about 160-170vdc across C131. I would expect to see 280vdc across C131 only if you were plugged into 208V mains. Also, the voltage you're seeing between pins 4 and 5 of the opto isolator is way too high.With...

Yep, if you're seeing input at the primary and nothing at the secondary, either the transformer is bad, or the secondary is being shorted by something externally.I have a hunch which would be simple to test: if the diode D114 was indeed shorted, the capacitor C128 would have a very low...

Oops, my bad on the secondary measurement. My Fluke needs calibrating. I'm getting about 0.8 ohms when I touch my leads directly together, so that does indeed indicate about 0.2 ohms for the secondary.Try to get a scope across the secondary while the unit is plugged in. You should see an AC...

You definitely should not be getting continuous beeping from your Fluke on both directions of the diode. That usually indicates a shorted diode. The transformer secondary should measure just over 1 ohm, not quite a dead short but close. I'm not sure what to make of C135 bulging.The BYD77 is...

This behavior would occur if the diode D114 was shorted. If your multimeter is capable, use it to test for a shorted D114 diode. And if you have a scope, see if there are actually several volts of AC present on the +12V point when the unit is plugged in, without your external 12V supply connected.

The newer products from Wireless Solution can operate at 5.8 GHz.

These lamps are used in the "battery powered candlesticks" that are popular during the holidays.Is this what you're looking for? http://www.elightbulbs.com/Gerson-03416-BATTERY-OPERATED-CANDLE-BULB-Light-Christmas-Replacement-BulbI believe that the E12 base is the same as C7.

There's a bit more to it. the MAX-15 lamp is physically longer than the MAX-7, so you need to replace the existing MAX-7 lamp socket brackets with these shorter ones:Lamp Socket - left Lamp Socket - rightThen you need to change a jumper on the main board:Atomic voltage jumper setting...
