121 No power

[Davenport]

Hi all,

Not sure if this is the right section but i purched a 121 recently, put the loco on the track and nothing working on either DC or DCC , ive taking off the body and all conections look fine, would anyone have any ideas?

Thanks.

I think we’ll need some more information. There are many possible issues and you need to rule them out to focus on the problem.

Do you have a multimeter to check voltages, resistance etc? 

In theory, is the loco set up for dc or dcc? 

Is it new or secondhand?

 

cheers,

Mol

Make sure there's power on the track. Check with another loco or multimeter.

Are you using Dc or Dcc & is the loco Dc or Dcc ?

Hi Mol,

Ive checked it both DC and DCC, its second hand , brought from an collection from  a man that passed away, yes i have a mutimeter but wouldnt know where to start , i have the body off and all connections seem fine.

Hi, yes i have power on the track and have used other 121s on that track. Thanks

With the body off apply power to the motor terminals to see if the motor works.

If the motor works then I would look at the pickups. Check the wheels, both thread & back to see if they're clean.

Use cotton buds & IPA

Thanks, sorry now but how do i apply power to the motor terminals? 

[amdaley]

If you look at a motor you will see two brush terminals where the wires from the pickups are connected.

You apply DC power to these terminals to see if the motor is active.

Make sure that you disconnect the motor from the rest of the circuit, otherwise you will get a false result.

I have had a recent experience with a 121 stopping suddenly-I cleaned the wheels and pick ups and added grease to the gears-no issues since.
