What causes Honda Odyssey EX L Battery Drain?
Knowing that the main relay/fuse circuit backup/ACC under the hood #15 was causing the drain I looked up on https://fusesdiagram.com/honda/fuses-and-relay-honda-odyssey-2003-2008.html. So I put that fuse back and then tried radio and that dropped it from 70ma to 20ma.
How did I find out my battery was draining?
The drain was found by going to each fuse dock and testing the energy draw readings with a meter to see if any system was drawing power when it should not be doing so as the car was off. The amp, an issue MB has had problems with a lot, was drawing power when the radio/car were off and slowly over the course of a few days was draining my battery.
What causes battery drain in Advance Auto Parts?
While you’re under the hood (or at Advance Auto Parts), test the alternator. A failed diode in the alternator creates a closed circuit that drains your battery even when the engine is off.
When to disconnect battery for Fuse pull test?
I did find a TSB that says that the computer might cause a draw only after it has been turned on and then off, so disconnecting the battery to set up the test gets rid of the draw if it’s that.
Is there a fuse pull test for parasitic drain?
I removed every fuse and everything plugged into the fuse box all at once and still the same draw. I unhooked the alternator, same draw. I unhooked the starter, same draw. I unplugged every relay under the hood and same draw. I don’t know anywhere else to look. Any help would be greatly appreciated!! Thank you. Mike
How to find the cause of parasitic battery drain?
Luckily, you can usually find the cause of a parasitic draw yourself. Start by connecting a digital multimeter to the negative battery terminal of your vehicle. Then, remove the fuses one at a time while watching for changes in the multimeter’s reading.
Can a seat motor cause a fuse pull?
In my vehicle these are covered by dedicated circuit breaker fittings not by the usual standard block of fuses and relays. I am aware of possible current draws occurring with faults from either of these items (ie. a faulty seat motor and a power window motor that continues to run due to a faulty switch).
