Roundhouse battery loco, pre-purchase questionnaire

"I also "touched" some live steam locos for the first time!"

Careful, you'll end up with no fingerprints or eyebrows!! :o
;) :D ;D ;D
 
Uh!! Oh!!
Another possible convert coming to the most addictive branch of the hobby known to man.
When that happens Mobi would do well to consider if his chosen R/C system can also handle live steam locos. ;)
 
Are the inside cab lights wired in same way as rear socket?

If I take out the bulb and send battery voltage via these wires, will the loco run?

Is the wiring of this lamp different based on whether loco is analog or DCC?

No

NO - Do not do this on a digital loco!!!!!!!!!!!!!! You will be stuffing volts into the wrong end of a decoder output.

Yes
 
Ok, understood - won't try ;)

What about analog loco? I have an analog Stainz too (basic model so doesn't have rear socket).

I am now in a bit of dilemma on which one to take apart first - the Stainz or Kof diesel.
 
Stainz = No space. A little awkward to take apart (especially for a 'beginner'). Already analogue, so stuff volts up the rear socket.. NO power on track, you will be fine..
Kof= More space. Relatively easy to take apart. BUT !!PLEASE!! remove the decoder for later use / to sell on to part-fund battery RC.

You can (almost) not destroy the Stainz, no matter what you do to it.
You can easily destroy the decoder in the Kof. - You would then have a 'dead' loco, the perception of which is you have 'failed' and wasted your money, even if you then get it going on battery.

You will find the KoF MUCH easier to dismantle than the Stainz - and it will have a lot more room inside. My advice would be to start on the diesel, use that to find your way around the inside of an LGB loco, then tackle the Stainz later.....

Is opening up the kof going to be similar as what is shown here?

Should be pretty similar.. If your is a more recent model, you will not need to have-at the motor-block. - You will have FOUR connections.

Remember, to get it to run, you only need two wires to the motor from a source of power.. All the rest, you can add-on later.
Also, check those bulbs.. if they have flat ends, they are 5V. - you will need to regulate the power to these, so as not to blow them.

Pretty much except you will not need to do any of those modifications. They are needed for DCC but not for battery R/C.
Isolating one side will be enough and you can use the existing slide on connectors to wire in the motor.

This might help. http://www.largescalecentral.com/forums/topic/11638
Surely best to totally isolate from track connections? - In case the loco is taken to another track.

All LGB screws are Philips type....

I doubt it. However some models, especially those not made by LGB, often have deeply recessed screws. I find this set

OK, something like this should work then?

I have several screwdrivers lying around in the house :D But don't think I have a magnetic tip one.
 
A magnet held on the side of the screwdriver blade will help.

Why would another track make any difference?
It cannot short out on a track with only one side of the track pick ups connected.
 
Mobi,
A real pleasure to see you on Sunday, the Chocy is perfect. Pity that yout time was som limited.

A few points on your recent posts.

Battery Wagon, I have altered one of the cheepo LGB Opens to have a Large Packing Crate as a Load. Seams to me that Battey Kit would fit nicely inside it. You could take the Body off, drill a neat hole and run your Wires to the loco across the Balcony or at the other end.

The Box is a simple Balsa Wood Box cover in Coffee Stirers. Technology that your daughter could assist with!

Another cheep option for a Bettey Conversion would be a Newquid 2-6-2t basically a clone of the LGB Loco with the Engine Number of 99 6001. The Radio and Sound on this are poor, but at less than £100 if you look round on Ebay would make a better option to learn the trade as it were.

For RC look at Timpden RC

http://timpdon.co.uk

I have one of these systems to possibly fit out my Newquid Loco with together with a My Loco Sound set.

You can get these in UK from Peter Spoerer

Looking at Screwdrivers the Maplin Set looks good, not sure about its Magnetic abilities though. You could take one of your LGB Screws in a small bag to a good DIY Shop and try various screwdrivers out for both Size and Megnetic ability. Most important that you get the Right Size as the wrong one can so easily Trash Screws.

The voltage regulator arrived but it is useless. My 8xAA batteries were producing 9 V. The regulator ate 3 V outputting only 6 V max. Loco decoder ate 5 V (as per loco manual). So what remains is just 1 V which was too low to power the loco [emoji19]

Then I connected battery pack directly with rear socket as shown in picture. The loco runs fine. [emoji3]

I think I need batteries that are stronger than standard AA NiMH. But then I need a charger for that too. The list just grows!

Of course removing decoder should help.

If you want 'something in hand', and to allow the batteries to discharge a fair bit before having to stop..
You will want a minimum of 12V from the batteries. Also remember rechargeable batteries tend to be 1.2V.

Others have more experience of suitable voltages for this style of working, but 14.4V is often mentioned.
