My BlueROV get a «leak detected» alarm often in the last dives. It occures from 10-50m depth. The alarm comes on, i remove it in the Qgroundcontrol program, and it can be away for about 1-10min before it comes back again. When i was down to 140m depth, i did not get any alarm. Recovered the ROV and had a look in the electronic enclousure on the leak pads, but everything was dry and seems ok.
I actually use toilet paper and wrap around one of the leak conductors a few rounds, then on the second leak sensor conductor, since the pads keep falling off.
Should i try change out the SOS leak sensor board maybe?
