So long story short I have a .5 amp draw while the car is turned off and the key is out. I don't even have the dash in, so there is literally nothing that should be drawing power.

I have narrowed the issue down to the 7.5 amp room fuse. with the fuse out, no draw. fuse in .5 amp draw. with the door light on and the room fuse in, .8 amp draw.

I am aware that the car would survive for a while with this kind of short ( maybe 3 days or so) but I would really like to figure this out before the interior goes back in so I have easier access to the electricals.

so my question is, how can I figure out what is drawing current, and how do I fix it? Or is it possible that NOT having things plugged in is causing this draw?

 

also, can anybody tell me what the room fuse controls?

I'm thinking of just cutting the power wire that goes to the fuse and putting in a switch so that I can just flip that and bypass the bad wiring wherever it may be. anybody know what wire that would be? 87 TII btw.

 

The electrical diagrams are in the FSM. Just figure out what is on that circuit and unplug things one at a time until the current draw stops. Don't cut the feed and install a switch

room fuse controls all the interior lights. start checking all the electricals that have to do with the interior lighting ( door lights, dome lights, glove box, lighter, ignition light, and hatch light)

 

do you have an aftermarket alarm in the car? if so disconnect it and see if the draw goes away.

 

I'll try disconnecting stuff, but so far I haven't had any luck. also no I don't have an alarm.

and thanks satch. since the only things plugged in atm are the interior lights it must be those

 

The ROOM fuse also supplys constant 24/7 power to the small plug of the ECU on a series four. I'm not sure which plug on a series five.

 

thats interesting since I have a series 4, and my haltech is getting main power but not the +5 vdc secondary

what could cause that? is it the haltech harness or could it be the stock harness?
