How to find a parasitic drain / draw on Vauxhall vectra 2008. Max 19 amps. Constant flat battery.

[@LucifersTear]

This awesome video needs far more love. I'm totally glad you didn't find the draw under the first fuse as the next steps was exactly what I needed, mine turned out to be the negative earth under the battery tray was corroded but was super helpful to see two more options (alternator and glow plug) check you performed would certainly help many people, Vauxhalls of this year and design almost all suffer parasitic drain at some point in my experience and I wish there were a OBD-linked sensor that would let you know things like this, wouldn't be hard for them to add.

great comment!

I had exactly the same. I was losing 2amps with a parasitic drain and found it using this video. In my case, it was a fuse under the bonnet which supplies the rear heated screen. I pulled the fuse..,the draw went to zero and I’ve never had any problems with a flat battery since. No heated rear screen but I don’t care.

Methodical, informative and superb fault diagnosis. Now post a video how change glow plugs please. Thank you. Best wishes

[@kidger3703]

Cracking video and such an easy way to find the fault. Maybe I'll calm down now 👍

[@deadlyevil2637]

Super helpful and straightforward video instructions, now to test my astra and hope it works

Brilliant video my friend I've got the same problem with my vauxhall combo I'm currently still investigating hopefully I will find the fault soon.

Thank you for this video. My opel vectra c 2004 is acting up, pulled all the fuses yesterday but forgot the boot box...

Not quite sure how a glow plug is causing parasytic draw? To my knowledge they are only supplied with 12v for a few seconds before you turn the key to start, therefore if they're drawing current all the time then the relay must be permanently energised or its contact is welded shut?

[@kenwarriner69]

exactly how can one glowplug cause it

[@noxious89123]

@@kenwarriner69 They can't! The fault is elsewhere.

[@LambySRI]

This should not be happening, the glow plugs are controlled by a relay and the relay should be cutting the power when the ignition isn't on :/

[@johnhealy9231]

Relay could be faulty (stuck contact ) I would have changed relay as we’ll .

really simply explained... shame they so knuckle bashing awkward to get at

pure gold. great vid.

[@mortierautomotive]

Great video!

[@DubT3ch]

Very helpful thanks

[@mainrig4981]

Why there is a parasitic draw at glow plug if contact is off?

[@liviu2004]

So you changed that glow plug ang guess what. That didn’t fix it! If the light is on in your room, you don’t replace the bulb to turn it off.
