Hello!

I need some help. I decided to check is there electricity leak of my Skoda's (Octavia І 1997, 1,6 GLX, electricity windows, central locking without alarm system). I connected the ammeter to the negative terminal of the accumulator and

I turned off all consumers, I closed all doors, cover of the engine and I locked the car.

So I became surprised - there was 0,12 A leak of current. The consumption is from fuse with number 14. According to the car manual it is about central locking and interior lighting. When I remove this fuse consumption becomes 0,00-0,01 A. When I put it back and I remove it something like a relay is ticking under the dashboard.

Is this power consumption normal for my car?

This is a picture of fuse panel: http://skodaoctavia.hit.bg/bushoni.JPG

Thank you in advance about your answers!

do the interior lights stay on at all?

other than check under the car after it has been stood for a while as you may have a small hole or nick in a cable and the electricity is leaking out onto the floor, check for a puddle of electric after it has been stood for a while

The interior lights are turning off when I lock the car. But inspite of that when I connect the accumulator or put the 14-th fuse on it's place something like relay is ticking under the dashboard (if it is a relay it works permanently when the accumulator is connected).

boot light stuck on?

boot light stuck on?

that's a very real culprit or glove-box light stuck on. Try removing these bulbs one at a time and look for a difference in your consumption readings.

The clicking sound is puzzling, might it be a relay for the remote central locking or the remote boot-release?

0.12A sounds about right for a car stood with everything switched off. It's if it gets up towards 0.5A you need to start looking for power drains.

I'm not sure if I've misunderstood you but the best way to measure power drain is from the negative battery terminal down to ground, with the negative strap disconnected.

my GFs old felicia draws 0.06A, so double for a newer car maybe.... I have never checked to see what my Octavia draws though

i agree everything is ok

Thought we had probs with a works van ---our auto elec said anything up to .25A (250mA) is OK -with meter on Amp range(start with highest, just in case) in series with a lead ( ie take a lead off, best one is negative ,as shorting this whilst taking off gives no probs and insert meter between lead and battery)

Yes, I do it in that way. I disconnect negative battery terminal and I connect ammeter in series.

Thank you for advices! Everything sounds to be OK.

dont forget to get a anti static mop to clear up the puddle afterwards

Have you measured the drain after the car has been stood for an hour or so, as the control units will power down. You will be looking for a consumer taking 12X0.12 = 1.44 watts which is too low for a bulb.

Yes. The ammeter was switched for two or three hours. The drain didn't powered down. It was the same for all period. May be it is some consumption in comfort module for central locking and electric windows.

Today I decided to check what is clicking. The noise lead me to the comfort module which is situated under the dashboard and steering wheel. I opened this module and I saw that the relay from this picture http://skodaoctavia.hit.bg/HPIM1588.JPG is working permanently when the car has supply from the accumulator and the 14-th fuse is plugged in, independently the car is locked, and how much time it is locked.

Is it normally this relay to works permanently?
