The charger I recommended will work but you will need to change the jack to 2.1mm or use chocblock, etc.

Have you tried the loco out as 7.2v is quite low for a loco that size?
No not yet - waiting on a new transmitter to arrive

It seemed to connecting into this box
The black switch is the power on/off switch connected to the Mtroniks speed controller (looks like one of the Viper range). So this power switch needs to be in the on position in order for the Run switch on the buffer beam to work properly.

If you do not have them, you should be able to download the instructions for the Mtroniks Viper ESC here (enter the appropriate Viper model in the search box) - http://www.mtroniks.net/

Looks like there are only 5 cells which does seem low voltage for this loco, particularly with a sound module as well.

Much healthier voltage for that loco!

The 1/4 inch jack plug is an audio plug, although it can carry voltage I would change that for a standard 2.1mm DC plug. The advantage being that you can likely use the same charger for more than one loco.

Hope you enjoy the loco, they are great, I have one that will pull the side of the house down.

Cheers

Sorry for the second post. I thought this may be handy..

I buy all my electronics from Rapid....they are cheap but there is a postage charge but they do sell things like glues, tools and thinners which are also cheap, it can make the postage charge worth it.

Hope its useful
