My smart junction box randomly decides not to shut down after a few minutes like it should when you turn the truck off. So this leaves me with random parasitic draw. I'm thinking the only way this can happen is if the battery saver relay is sticking. But... I cannot find a battery saver relay on this stupid truck. The older trucks that used a GEM had the relay behind the radio but not on my truck and not in either fuse block.
I have definitively sourced it to the SJB the circuit that stays on is fuse 33 (instrument cluster battery feed b+) and fuse 11 (SJB logic power). These both SHOULD disconnect after a couple minutes but like I said sometimes they just stay on forever.
Disconnected all other fuses when testing, doors latches closed, don't hit the brake yadda yadda so I'm sure not to "wake it up".
Any ideas? It's an absolutely random occurence. Sometimes it shuts down and I have barely 10ma parasitic draw, but when these stick it's about .200ma.
