Where is the battery saver relay on an 09 with a SJB not a GEM?

[Dirtman]

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.

OK, so I can't get the picture from the online EVTM to render properly as an attachment here, but if you would remove the SJB completely, and hold it so the fuses face you, and the SJB roughly resembles the shape and orientation of Nevada, the accessory delay relay is the big one between Las Vegas and Reno on the California border. Much closer to Vegas than Reno. Like right where Nellis AFB and the Nevada testing range are.

Have a look here: http://cyoum84abk-flywheel.netdna-s...d-Ranger-Fuse-Diagram-Smart-Junction-Box-.jpg

The Battery saver relay is in the SJB from 2004 to 2006

I show it as separate from accessory relay until 2006 then it is no longer listed at all as part of SJB or as part of any circuit

Yea mine just has a blank spot where that relay would go.... if there's no relay what the poop is physically responsible for disconnecting all that nonsense? Now I'm even more confused. I've been out here fiddling for hours. Had it shut down once (only takes a couple minutes) tested it again and now it's been stuck on for 2 hours.

LMAO.... That right there is some funny stuff.

Yea see... I know where the relay SHOULD be, but there's nothing at nellis air base! Just a blank spot the shape of a relay plug... government cover up?

check in Area 51, theres a lot of crazy over there.

 

[Dirtman]

See! Missing! So with no relay what actually turns crap off? Something in this dumb thing is sticking open...

Ignore the strange wires that don't belong or go anywhere...

They moved it to Area 51.

Really without the relay nothing in the cab should work, like your chowder radio.

Unfortunately in 2004 they changed to SJB and Digital cluster(HEC), this means any problems with these require swapping out the whole unit usually

I 100% assure you there has never been a relay there. There aren't even terminals for a relay to plug in that spot... it's just a blank hole. Everything works. Always has. Just this new nonsense with the timer not working.

I know the cluster is not replaceable without getting the dealer involved since its married to the ECM and Pat's system, can the SJB be swapped out though? I can grab another one for 20 bucks or so from the junkyard. And it seems fairly simply to pop in and out.

If you have a used SJB, assuming it is the correct part number, you should be able to just put it in and go. You will need to program your key fobs again, if they exist, as those IDs are stored in the SJB, but that's a simple key dance.

No power locks.

Ill grab another sjb tomorrow if i can find a match. Since i have a base model xl with zero options is there any issue using one from a truck with more options like power windows, cruise etc? Obviously the connections just wouldn't go anywhere but thats how mine is anyway. The stuff like power windows just dont have fuses installed.
