Bio Cube Moon Lights

[smitty]

The Moon Lights in the stock hood of my BC29 are not working. I cannot imagine the the led's are all burned out, I suspect it's the power supply. The problem is, it's a 4 volt power supply & I don't have another 4 volt power supply to plug in to check them, all I have is nine volt for like keyboards, etc. Anybody have an idea of how to check them or the power supply to see which is bad?

if the led's were wired in series, if 1 burns out they all go out kinda like christmas lights.

use a multimeter to test power supp. if its ok take the light apart and follow the sequence of the lights with the multimeter until the meter reads zero.thats the bad led. must keep one side of the meter on neutral line in if the lights are wired in series to successfully find the burnt bulb. then soldier a jumper accross led to bypass. wala fixed.

The power supply is OK so I think next time I have the lid apart to change bulbs I'll chase down which LED it is. Thanks for the help!
