I have a 2002 Toyota four runner that has a parasitic power drain that kills the battery.
I have a 2002 Toyota four runner that has a parasitic power drain that kills the battery.
This is the steps I have taken so far.
1. Disconnect the battery
2. Turned off all electronics
3. Remove negative battery terminal
4. Clipped one end of a test light to the disconnected negative battery wire
5. Noticed that the test light is lit
6. Removed all fuses and relays under the hood and in the cabin one by one but the test light went out
7. Removed the main heavy gauge wire on side of the alternator that bolts on with a 12 mm nut
8. The test light goes out at this point
9. Removed alternator and currently buying a new one
Can you check my logic on this ?
Thanks for all the help !

now the alternator is connected i still get the light but it is very faint , is this normal ?
I do have a multimeeter but not sure how to use it in this situation to further diagnose the issue
I am going to replace the battery next
I think that there is a small draw , but the battery is old to , so if I can get enough charge and the parasitic draw is small enough maybe it can start after only 12 hours sitting ?
I would like to use the multimeter in place of the test light to come up with a number , but what setting ?
thanks again for all the help!!!! I really appreciate it

The alternator will only generate power when the engine is actually running. Did you perform these tests with the engine OFF?
yes OFF
yes OFF

I think what I have to do it not use the TEST LIGHT but use an MULTIMEETER to look for AMPS draw , maybe it is acceptable now

"If the ammeter is reading over 25-50 milliamps, something is using too much battery power."

You have to disconnect each fuse one at a time until you see the problem go away.
You may have a open in the relays.

thanks alot for all the advice , I did not know that you could use a multi meter in that way !
MY BIGGEST MISTAKE WAS TO USE A TEST LIGHT AND NOT A MULTIMETER,
THE LIGHT SHOWS A ARBITRARY ON/OFF CONDITION THE MULTIMETER SHOWS NUMBERS !!!!

I made an error on this
this Should be Removed all fuses and relays under the hood and in the cabin one by one but the test light NEVER went out
I have replaced the alternator , and I am still getting a very week light when I connect a test light to the negative battery terminal and the negative battery cable after the battery and the negative cable are disconnected
