Has anybody ever figured out how to add an alarm to the factory sensor lights. I would like an alarm to be wired off the full sensor light wires. I have a #2 grey tank that Leaked when over filled. I have already pulled the tank because it leaked from the vent when full. I did the repair and filled the tank to test for leaks, left the under belly cover off for a few days and noticed a new leak. I was surprised to see the tank leaking from a pre existing patch! That means in 2014 Heartland installed a patched tank in a brand new trailer. The trailer had only been used for 3 months when the elderly couple put the trailer up for sale due to health issues. I called Heartland for a replacement tank and got a whole 5% off due to their shoddy work. I installed the new tank and a few months later it started leaking when over filled and I really don't want to pull the tank again. If I can figure out how to set up an alarm to the red full tank sensor wires then I can install new insulation for the 3rd time and be done with it. I did install Horst Miracle probes on all 3 tanks so it would be nice to not have to but a tank sensor system with an alarm.
