LGB 23510 V52 bo-bo locomotive non runner?

[lgbmad]

Good afternoon all
I recently acquired this loco that is in mint condition factory fitted with MTS, also a LGB 65002 sound unit had been fitted.. To be fair the auction site did say it was a non runner when I purchased it, but I thought it was worth the gamble. Sure enough it is a non runner, but as stated the loco is mint . I tested the loco in both analog and MTS. The sound unit itself sounds great….but the loco does not move and there are no lights at all. I did try switching the three point switch on the underside ….sound on all three settings but still no movement or lights .
Who ever owned the loco looked after it really well and all the documentation etc was all present in the original loco box.
As yet I have not ventured inside the loco …..thought I would ask for advice as to what I should be looking for First.
I would appreciate any advice please.
Many thanks .

I was going to suggest the switch. I had a similar problem on mine. Try moving the switch back and forth, as it might be a bad contact....

I agree with Gizzy:
Wang (technical term!) the switch back and forth a few times..

Other than that, it probably means going into the loco? - If only to see if there are separate motor and sound decoders?

You could try (if the loco is on other than address 3) seeing if it responds on address 3? - If there are two decoders, and the address was changed/reset, only one decoder may have changed.

Long-shot, but possibly worth a try, before getting the screwdrivers out.

Ah ha, it was your good self that got that lovely looking Diesel from the SAS sale, think it had been returned from another sale the auctioneer said before it was opened up for sale. Thought it might be a good RC conversion because of that as you remove all the gubbings inside.

If it not getting power in from either of the pick ups on the two motor blocks and thus triggering the lights ( from my experience it only needs one to work for power, and it doenst have a panto) I bet the main board is the problem, somethings fried or unsoldered/uncliped . Sould be easy to open this up. I look forward to hearing about this mystery. Parts Diag below.

It was indeed that same loco, but thought it was worth the gamble at £130. The sound unit alone is probably worth that.
Thank you all for the input…..I will have a fiddle first with the switch and go from there. Once the loco is open I can always send in some pictures unless something jumps out at me in the first instance……like the motors are missing……lol.

Thank you Phil….the sound unit is definitely on code 3 as I set my hand set to that to start with knowing a lot of locos are usually still on the factory pre set.

Drop out the motors (can be done from underneath) and make sure they are working as a first step.

If they are, and the mechanism is otherwise turning freely, you have an internal wiring issue to deal with.... but at least you will know it is not a mechsnical problem.

Get the manual form the web, search for....( LGB 23510 pdf ) Instruction manual, also search for ( LGB 23510-2 pdf ) Cable diagram. The motors are active on 2 right positions, all off on leftmost position. And check for track power at the 2 end external cable sockets (bottom middle remove dummy plug).

Thank you for the info……I will be going in tonight hopefully….lol. Update to follow. Thank you.

If the lights come on but no motor movement, that can mean the motor, not the main board, is defective. But with your locomotive, it has two motors and it's highly unlikely that both motors would fail at the same time. So, my conclusion is the factory-installed LGB MTS (DCC/DC) Onboard Decoder has failed. But you could Read CV1 to determine the currently assigned address to test in DCC, but regardless of the assigned address it should also operate in DC analog. According to the locomotive's User Guide that contains all the CV settings for the Onboard decoder, you could also try a decoder reset, CV55=55 using your DCC System's Service Mode Programming. But again, when I've encountered your situation, I've never found a reset solved the issue, the Onboard decoder was dead.......your model was manufactured by LGB years ago during 2004 - 2007.

If the Onboard Decoder has failed, then obviously you'll need to install a replacement such as a Massoth XL Driving Decoder and continue to use the LGB 65002 Sound Module, or, my preference instead of using two decoders, install a some brand DCC sound decoder such as Massoth XLS or the Massoth XLS-Onboard which has all the sockets for the locomotive's cables and plugs so you don't have to cut them off to install the decoder. I consider the ESU 5XL DCC Sound Decoders one of the best on the market for G scale, with its superior sounds quality and sounds features (30 F Key Assignments), but you do need to use an ESU LokProgrammer to set them up due to their complex design instead of just using a DCC system.

Good luck!
