The USB Battery Charging Specification allows up to 1.8A. It's the maximum current (and therefore power) options within that limit that vary between the different Apple chargers. Jonathan PS: More about Powered USB, but I don't think it's relevant to this purpose. I hadn't heard of it before. Edited by - Jonathan Kay on 12 Nov 2012 14:19:45

Quoting cskip: It is also worth noting that there are 2 different and separate power outputs available from USB. 12V and 5v. The input that is needed for charging the device can vary. As an example iPhones/iPod Touches did support both 5v and 12v up until 3rd Generation (going from memory here so I could get it wrong), 3rd Generation onwards used 5v only. As you can imagine this caused a few problems for third party devices (like iPod docks) that used 12v to charge and new generation iPods wouldn't charge.I don't think so. USB voltages and pins are defined by standard. But different Apple chargers deliver different maximum currents. This mostly affects time needed to recharge a device.

More advice on testing Jonathan

Ok guys. I'll ask for confirmations when I have more details. But I am feeling a bit less financially exposed! Jonathan

As above. What's the model of the charger? Get the battery charged somehow, stick it on the charger, then check what's happening every day by briefly disconnecting the charger and measuring the voltage. Then reconnect to the charger until the next test. Jonathan Edited by - Jonathan Kay on 11 Nov 2012 18:51:08

... we don't know the intended use. Is it only for power or will you be moving data through it? If it's only for power I'd probably use an adaptor too. Does everyone know about the EU's decision that mobile phones sold in the EU (etc) must be able to be charged from micro USB? There are similar decisions from other industry and standards bodies. That might mean that micro USB will become the de facto standard for other power supplies. Jonathan Edited by - Jonathan Kay on 11 Nov 2012 09:54:40

I searched Google for panel mounting usb socket and got lots of hits. Is that the sort of thing you're looking for? NB There are a few varieties of "USB socket". Jonathan Edited by - Jonathan Kay on 11 Nov 2012 00:14:41

When I know the shipping date and what the final total cost will be, including getting them to you all, I'll ask for confirmations. I think there'll be about 20 spare if everyone confirms what they've said. Jonathan

They have been ordered, including a few spares. I've asked for them not to have the yellow printing on them. They are shipping from China and I don't yet have a delivery date. Jonathan

I have a recumbent trike and I think someone else on BC does. Never ridden one with electric assistance but lots of people in the HPV world say what a good solution they are. Have you advertised it on the BHPC site? Just noticed you have! Jonathan Edited by - Jonathan Kay on 8 Nov 2012 19:22:42

Was it turning over on the starter as quickly as usual? Jonathan

I'm not sure I agree. Mk 1 eyeball remains my preferred method of filtering. There have been lots of postings recently that I'd prefer not to have read, but I don't have a right not to be offended. For me they mostly come in two flavours: personal comments and stigmatisation of outgroups. But I'd still prefer a bit more care about netiquette to technological filters. Of course this might be a response you'd have had turned off! ;-) Jonathan

We used to use Blackbox for things like that. "Radio Spares" say they have gold-plated. Jonathan Haven't soldered one of those for ? 10y

There's a link in that thread to something from Maplins... Jonathan

Does this help? Jonathan

Quoting anthonym: our local kids take pride in knowing just where to kick each street light so it goes off. apparently. Anyone know if this is true? I've never heard of it, but I have heard about Street Light Interference. Jonathan Edited by - Jonathan Kay on 3 Nov 2012 20:46:06

Advice from Stu in the preceding post. Do you have a battery master switch? Do you have an immobiliser? Jonathan

Quoting sforshaw: Martin, basically the Rover MFRU (multi function relay unit) which is mounted underneath the ecu is not up to the job of driving the starter solenoid. It needs a secondary relay .... Firstly (as I mentioned in the text you've copied) is to break into the feed (brown/red) from the MFRU to the solenoid and insert a 30A relay. Take the brown/red coming from the MFRU and connect it to the coil side of the relay together with an earth from the battery to the other side of the coil - use black cable for this connection. Turning the ignition key to the starter position will now cause the MFRU to activate the coil in your new relay, closing the switch across the other half of the relay. This will put minimal load on the MFRU which is where the problem probably is. Now, take a new feed from the positive side of the battery (4.0mm red) and connect to the switch side of your new relay, then connect the other side of the switch to the remaining brown/red which runs to the starter solenoid. What happened previously ... turn key, relay in the MFRU closes to send high current to the starter solenoid, but in doing so overloads the MFRU and not enough current gets through. Now .... turn key, relay in the MFRU closes to send low current to the new (beefier 30A) relay, which in turn allows a high current feed to the starter solenoid directly from the battery If this fails then bypass the MFRU completely and take the feed from the ignition switch (one of the other wires going in to the MFRU but can't remember which).

Quoting Nigel Mercer: So what about jacking / axle stands at the rear? Do we have a consensus of how / where? Sources: 1 Your own manual 2 Club FAQs 3 Alcester Racing 7s Jonathan

Does this help? Jonathan

There's a comment above about concrete blocks. I'm sure everyone on BC already knows the advice about never getting under a car supported on concrete (or similar) blocks, bricks etc. Here's the club FAQ on jacking I use the towing eye. Jonathan

I spy project creep. Jonathan

Always been 7 continents in my English experience. Wikipedia actually has data on how many continents are recognised* in different parts of the world. Jonathan That means "recognized". :-)
