Re: [Amel Yacht Owners] Strange 24DC leakage



This Amel-made bonding system check device is simple and masterfully accurate. The type of thing the you expect from Amel...very Amelish.

I wonder if what you describe could be caused by the test circuit itself since it is the source of the power to light the bulb, while the "switch" to turn ON the bulb is any existing connection between bonding and the selected post of the 24 volt system at the moment of switch activation. What you describe is a diminishing resistance of that electrical connection, over time.

I'll be interested in what people, who know more than I do, say about this.

Hi everyone, 

Our DC leakage detector is showing a leak on the negative. I investigated any AC charger + DC USB potential issue as mentioned previously on the group and didn't find any culprit. 

However, it highlighted this strange fact: when I push the switch up to test for bad connection between negative and grounding, the light comes on and slowly goes off in about 3 seconds. If I test again, it doesn't come on. I need to wait for 10 , 15 minutes for it to 'recharge'. It looks like a capacitor discharging. 

Has anybody experienced this before? Does it give a clue to what could be the source of the leak?

Otherwise I'll start the usual investigation disconnecting everything from the batteries end.

Thanks in advance,

Fair winds
