The bulb in my dome light went out a couple weeks ago and has just started draining my battery with a 0.01a draw.
The fsm says the clock is on this circuit. I dont have my elec diagram on hand. Does anyone know if theres anything else on this circuit?

Thanks

 

Sorry for the delay in my reply. I wanted to comment sooner but have been busy with home remodeling.

What year is your T100? What engine?

A 10 milliamp draw isn't that much, and might even be normal. I am not sure what the draw is supposed to be when everything is "off".

We will need to find a wiring diagram.

Do you know why the dome light stopped working? Is the bulb good? What condition is the battery?

How did you measure your current draw?

I know, so many questions!

I am certain that there are several more things that run off of the same circuit as the dome light.

If your T100 is wired similarly to the early-mid 1990s Trucks and 4Runners, then the DOME Fuse feeds the dome light, map lights (if equipped), courtesy door lights (if equipped), memory power to the clock, memory power to radio, possibly headlight reminder or daytime running light control, and possibly other loads. I will need to find a diagram to confirm this.

Does removing the DOME fuse remove the draw?

 

Thanks for your replies...im moving house right now so the fuse is out for a couple weeks until i have time to assess.
The battery was done. No idea how old it was.
I tested the draw just with a harbor freight multimeter. I have been told that electric draw should be less than 0.01 but that is just a loose rule of thumb thing and not vehicle specific. Plus you know how ppl throw arnd info...
But in my experience even a 0.02A draw will drain a battery over time. So i wonder if a 0.01 reading could be 0.015 if the multimeter cuts a digit off.
Ill get you some better answers soon but right now the workhorse has a bandaid.
But i did get new bilsteins for the rear!! Very excited
