I have a 91 V6 T4R. I had some charging problems lately and replaced the battery and had the alternator fixed. Everything works fine. But now the battery is getting drained when the car is off. I measured the drain when everything is off and it's 0.11 Amps. I disconnected the dome fuse and the drain dropped to 0.01 Amps. I read on another posting that it should be between 30 to 50 mA. I also noticed that when you turn the ceiling light with the switch, the light is stronger than when the door is opened. I have nothing installed except for the radio which was off of course when I did the test. Any suggestions as to what could be causing this? Thanks.

What you are testing is called parasitic draw. Now that you have the problem isolated to the dome light fuse, you need to investigate the entire circuit to see what other components are powed by that circuit. Do any of the componenets on that circuit consume power while the ignition switch is off? Answering that question will help you diagnose the problem further. A multimeter should be all you need to narrow it down and find the real source of the power draw.
It appears that the dashoard clock is draining 80mA. I was wrong about the fuse though, it's not the dome fuse but the CIG fuse. I measured the current draw on the CIG fuse and it's 80mA. I disconnected the clock (had to remove part of the dashboard for that) and the current draw was 0. Now my question is, is the clock light on when the ignition is off? Cause I have a feeling it shouldn't be on and I can't remember if it used to be on before I had this problem.
Is there an electrical wiring diagram for the T4R. I have the service manual (for the pick up) but I have a feeling it doesn't have all the wiring on it. Thanks.
