anyone else had a battery drain from the ctsy fuse line? I have messed with this for a week now and still cant find my draw. If i pull the 20 amp fuse it goes away but is seem that feeds so much like door locks,dome lamps,radio,lighter but all the diagrams only show the door locks. This is killing me .lol

 

Do you mean the ACC fuse, can't find one on my diagrams called the ctsy. Now you've narrowed it down to the fuse, unplug the devices powered by it one by one, until the drain goes away. If it doesn't, that leaves the loom itself.

 

I have the same issue on my 87 TA. TreeFiddy, what do you mean by that the problem is in the loom? Can you clarify this.

Thanks

 

Meaning that if you have a circuit with all the powered devices that are on it disconnected, and you are STILL getting a power drain, there must be a problem with the wiring itself.

It's unlikely in this case, usually a wiring problem will be either a fully or intermittently open circuit, which will just cause the circuit not to work, or a dead short to ground or other wiring, which will cause the fuse to blow.

However, on various cars over the years - I have come across a situation where insulation between two wires had deteriorated and somehow allowed a low resistance between them, but not quite a short. Similarly with a wire going thru a firewall, not correctly bushed. Also think I had a connector on something once that filled up with years of goop around the terminals, which conducted a bit. That kind of stuff - not fun to track down.
