Take your array apart and sand/grind the shit out of the metal connector, make it NICE and clean along with any new bolts etc to verify there's no corrosion.
What's happening is there IS a connection, but it's shitty. Hence it works a couple times and stops. (so frustrating to have a system in place and have it work so intermittently)
If anyone is interested I have a working system that i'm willing to part with for cheap along with a procede controller. Willing to sell it all for ~$1000 obo

To piggyback off this. My WMI failsafe had started working somewhat intermittently and progressively getting worse. Basically Kept triggering a false fail-safe. Anyways the issue turned out to be the spot that i was grounding to had started to kind of corrode and rust a little. Took a long time to trouble shoot this because it really didn’t even look bad but i sanded it clean and reground and throughly covered the ground wire/ground point that was exposed with electrical tape to prevent water rust/corrosion. Long story short its been back to working flawlessly for over 2 months with zero triggers. Before it would trigger 5 times a day. So make sure all grounds, connections, conductive points etc.. that are exposed to the elements are not losing connection from rust and corrosion being in the engine bay.
