2000 Honda Civic battery drains when car is sitting

My car battery drains when it is off. To avoid draining I have to disconnect the battery everytime. I noticed that sometimes when I'm trying to disconnect I hear the AC clutch relay getting disengaged and if try to connect the battery back I hear it getting engaged. I'm not sure why the clutch is getting engaged even if the car is off.

    I'm sure that AC clutch is drawing the current. But the clutch relay, supposedly, can only turn ON when ignition is ON. What do you think may be the reason why clutch engages even when car is off.

It's called a dead short if you take off the + battery terminal and scratch it across the post of the + it will make small sparks if there is a draw. there shouldn't be any sparks at all unless something is on drawing power / eg clock will draw verry little and you almost wont be able to see any sparks or if you have a major draw it will spark like wild fire . if it sparks wildly , start unhooking things that you suspect drawing power and check for draw . might need to get a-c pump serviced. but find the power draw first.

New battery keeps going dead when car shut off overnight

Sounds like a slow drain - like a dome light or short in the wiring.
If the battery stays charged when it is disconnected, you'll have to check for a power drain in the car.

Battery issues

CHeck and see if yopu have a parasitic drain on the battery. Sounds like something is staying awake after you cut the vehicle off. To check this, disconnect the battery, place a test light between the negative battery cable and the negative battery terminal. If it lights up, there is a draw. To isolate it, begin removing fuses until the light goes out. When the light goes out, you have found the circuit the draw is on. Then repair the draw

2007 civic si battery drain

Seen this "mystery drain" many times. Check spark at the battery to see how big the drain is. For this simple test, blow away any (explosive) battery charging fumes. Leave one terminal on and gently touch the other to its post in fairly dark surroundings. Then try it again with the wires taken off the alternator. Your spark is now probably much less. Usually bad diodes leaking electricity backwards through the alternator cause this drain. Replace the alternator or the diode pack inside it. Some mechanics recommend actually measuring the drain.... hahaha. OK whatever.

2000 Honda Civic AC Clutch relay engages even when car is off and drains the battery.

you need to check the A/C clutch relay in that circuit as the contacts of the relay have welded themselves together from the high current draw of the clutch coil and replace this item this will solve your problem of being on all the time and draining the battery

Car won't start after rear-end collision

Sounds like electrical drain-
Trunk light on, dome light staying on.
Something along that line.
You could try pulling the associated fuses until you get the car in for repairs.

AC Clutch engages as soon as battery is hooked up

Your A/C relay may have gone bad and has disconnected the power to the A/C compressor clutch.
Not sure where the relay is to your A/C, it may be in the fuse box but regardless check the relay and replace if it's seized. If you like in the mean time, you can always disconnect the wire harness to the A/C compressor clutch to keep the battery from draining and save your compressor from over heating.
Good luck and hope this helps. Keep me posted and be glad to help.

Central locking


First of how do you know if its actually the central locking thats draining your battery??? did you disconnect it and see if the battery still drained?? can you hear any noises coming from it when your inside the car as if its trying to open or close???
only thing i can think of is

If you have a rectifier go out on it.

A rectifier is basicaly a big diode. It allows electricity to flow one way. If it fails, electricity is allowed to go back thru it to ground while the engine is off.

or it maybe simple like a boot light not going out!

best of luck :)
