Problem with timer leak...

[Congaken]

Have a Fusion 10 with Skyelight...I've tried several common timers and 2 of the Skylights...If I see the tank in the middle of the night, the led's are glowing and there is a feint smell of electricity...obviously dangerous!...any thoughts about a better timer that will not leak juice to the led's?...I'm pretty sure that there is no salt creep down there...Thanks...

Are you sure the LEDs are on and you arent seeing the reflection of light from something else? These timers typically involve a physical disconnect modality so there would not be a way for current to leak through. Does it click when it switches on and off?

Do you have a multimeter?

I am sure that the LED's are glowing...not a reflection in the middle of the night...everything is black...this is not an aquarium timer, digital and non- digital units were tried...I assume they click when they go on...the on and off are working properely...have in mind a better unit?...what should I look for and what's a multimeter?...I'll google that...

A multimeter is used to measure electrical signals. You can get a cheap one line just to measure if there is a voltage on the line when it should be off, as you suspect.
