Hello and welcome to the forum!

The readings below (all measured at the battery) in the first table (ignore the second table) are typical values for a 2000 4Runner.. Thought these readings and the following info might be helpful, depending the specific features mentioned below that your '97 has..



If your '97 has the security system and power windows (functions performed by the so called "body ECU", and wireless key fobs which requires the so called "back door ECU/radio" (because that's where it is located) I would guess your normal drain readings would be similar to mine. Both of the above mentioned computers run all the time. The Toyota service manual states parasitic current with everything off, doors closed should be under 50ma.

In the readings above, as noted all dome lights were turned off, but note how the readings change, when doors are opened. This is due to body ECU coming out of sleep mode into operational mode..

The body ECU in operational mode draws enough power to run the battery down, if for example as I did, switched off all dome lights and left the doors open overnight (to dry out the carpeting that got a bit wet).. But if your '97 doesn't have these systems, we can move on to the items below.....

I'd suggest you buy a Volt-Ohm-Meter (that can measure small current loads, if you don't have one, and make the exact drain measurements as that may be helpful in isolating..

Other than the above, the clock, and off course, the dome lights themselves, the door ajar light in the instrument panel, and if you have them, vanity lights in the sun visors are pretty much it for the loads on the dome fuse circuit, per the 2000 model factory service manual..

Lastly have there been any wiring modifications or accessory electrical gear put in your vehicle?

Please post back here which of the items mentioned above that your vehicle has, or does have.. That will be helpful in deciding what to look at next..
