This Vauxhall Astra Mk 5 van is constantly having a flat battery so we check to see if the alternator is charging and also perform a Parasitic Draw Test to see if something is draining the battery. We also check to see if there is a problem with the vehicle earth strap to the chassis.

Very good video Martin. Amazing how a simple connection can look perfectly good. But the corrosion between the connection is the problem. Another area to watch out for is the wire going into the connector. Usually they are covered with shrink type covering and corrosion loves to hide there as well. It look perfect, but far from it. Thumbs Up!

Thanks that was absolutely just the information I needed. My Astra J van had exactly the same problem and I had eliminated it down to the fuse 35 as you did, the 'infotainment' system. What I didn't know was how to check the earth resistance. I suspect that mine is doing the same thing. I will check as soon as the battery is up to charge. I wish I had seen this before I started finding out the what the problem was, all the information required would have been there. Im not entirely convinced that the alternator replacement that I had a couple of weeks ago at great expense was necessary but its too late to check now. Subscribed.

@tonyurmate 8 месяцев назад

I put a new battery in my opel astra H last November and I noticed in the last couple of weeks it sounded like the battery was slowly going flat when I'd start the car in the morning. I did as you did diagnosing the drain on my battery and it was the radio that was causing between 1.24 and 1 amp drain so I removed the 10 amp fuse for the radio. This was very helpful, thanks.

@cabdriveruk 4 года назад

Great video Martin. 14 v from the alternator is correct and good. I bet someone in past has been connecting something to radio live and probably left it in place. Always a good idea to check earth connection before the bad weather hits. Cheers, Jeff.

Like a lot of things these days, far too complicated and trying to bypass basic electrical principles for people who don't understand them. All the gear and no idea, springs to mind! 😂😂

@computertechy 3 года назад

Thanks for this video! The 06 zafira same engine has been a real pain in my arse, no load idle voltage was 14v, everything on was 13.43v no change when revved. Cleaned the earth strap under the battery....13.9v fully loaded, 14.1v idle no load. Every now and then it will require about 4 cranks to start so hopefully this will cure it. The draw test showed 0.35ma.

@stevev3664 Год назад

One thing to mention is that on a battery that is not new you can have an increased internal resistance in the battery due to age. When testing the battery with a meter it can show 12 volts at the terminals when not under load but when the starter motor is engaged the voltage at the battery terminals can drop to 8 or 9 volts. This is not enough to turn the starter motor over. I had that problem. It doesn’t apply to the battery in this video because the battery was new but worth remembering for older batteries. 😎

@paulyh4531 4 года назад

Pretty Polly is the problem someone prob rigged it up to permanent live 🙄😉 let us know the outcome Martin , good vid as always 👍

@noxious89123 3 года назад

It's worth noting that Vauxhalls will switch off extra equipment after aprox. 30 minutes, after you've taken the key out the ignition and shut the doors. So that 1A draw would/should/could drop down to much less after 30 minutes without touching the car (the battery would need to remain connected for this time! Otherwise everything will reinitialise as you reconnect it, and you'd have to start timing 30 minutes again).

It took me 3 charged up batteries to find fault in the end like you did with pulling fuses. My problem was a faulty glow plug relay staying on all the time. Luckily it’s starting ok in this cold cold weather so glow plugs seem to be working ok. I wouldn’t want to be taking those out with over 200,000 miles on the clock. Keep up the good work on the great channels you have mate. 👍

New subscriber here thanks alot this may cure the problem i am having on my diesal mokka same engine

@Wiltshire-observer 4 года назад

A good logical fault finding video. The engine earth strap or battery earth to chassis is a classic fault on cars with a few years under their belts. The large terminations of these connections do get corroded quite often. It’s worse if they have been disturbed at some time and never cleaned up. Different metals pushed together will corrode fast. With a so-so battery voltage of less than 12.5 volts, a very poor earth to the starter motor will make it crank very slowly, or not at all. A fully charged lead acid battery with a design voltage of 12 volts is fully charged at 13.8 volts. Under load it might fall a bit below that, but the alternator will still charge it above 12.5 volts. If the charging current goes too high above 13.8 volts it could overcharge the battery and this will eventually lead to it drying out. Modern sealed batteries cope better, but too much voltage will also damage the battery. A good vault finding video here, logical steps taken. There will always be a few hundred milliamps drain on the battery when the engine is off. The alternator diode pack will allow some reverse current when idle. Amps of drain will of course flatten the battery....

Great video, super helpful and I'm betting its the parrot system causing the issue, hate them. So many of these had parrot systems installed and they're a nightmare! Super helpful video especially for these Vauxhalls, so many of them have ended up in the tat yard for power drain issues. I've had 3 that have suffered this. One was the Nav system connector (parrot fault), one was the Dashboard instrument cluster set (corroded at the back must've gotten wet inside) and on my most recent one the headlight light connectors were full of crud. Other people suffer with glow plug shorts and alternator diodes. Could make a fortune just fixing this issue on these 04-10 Vauxhalls 🤣

@stef2198 4 года назад

A little info regarding the battery testing. Unless there is a load on the cables, checking the voltage at the post will be the exact same as the connector - simple reason being there is no load to create a bolt drop. I try to explain this to apprentices in the simplest manner I can, take a 1 meg ohm resistor, put 12v on it from a battery, what is the output voltage? Without a load it’s 12v still. You have completed a circuit so there is nothing to create volt drop. Hope this helps someone, happy tinkering.

@retrorestore 4 года назад

Not if the post connections were corroded. You would see a lower voltage that would be confirmed by putting a load on them and see a higher resistance and possibly heat generated at the joint. I've had many terminal at a starter motor for example where the post supply is 12.4 volts but at the starter motor end of the cable only showing 8 volts for example. A clean up of terminals corrected the issue in all cases.

@stef2198 4 года назад

the cars electronics are likely what are causing that voltage drop you see there between the post and the starter, as there is load on the terminal/post even at very low milli amps which would be enough to create a drop.

@retrorestore 4 года назад

@@stef2198 No bud, You should see the 12 Volts at the starter from the big cable direct from the battery. I do know, I was a sparks for 25 years

@stef2198 4 года назад

retrorestore I’m not saying you won’t see 12v at the starter? Nor am I getting at you. What I was pointing out was without load (depending on how bad the situation is very small or moderate load) you will see different volt drop conditions. A small amount of corrosion causing a resistance would be nothing until you try pull a load which is what I was getting at from the start. For you to have dropped to 8 odd bolts must have been pretty bad. But if you isolated every last milli amp of current draw from that battery, corrosion won’t drop the battery voltage without some kind of load/circuit. Which is why in the trade even a simple light bulb/test light is a much better tester than a multi meter - when trying to find a wire which may have rubbed through, green crusties set in But according to a voltmeter you still have 12v, apply the light bulb and it says otherwise. 12v into a resistor still gives 12v out, until you apply a load.
