Hi all I need a bit of help or advice, my LGB 20232, 2-4-0 was running lovely last week all was working well, now I have movement, sound and smoke but no directional lights, I have opened her up and can find no wires missing or broken, there doesn't seem to be any power for the lights on the circuit board as I have tried to connect another LED light to it. Am I missing something? Can someone help as you all know i'm a bit thick when it comes to locos and electrics. Thanks.
 
Paul,
We need to know if you are running DCC or analogue?

The lights may well be bulbs, not LED's..

If you were trying to test out with a LED you may have got the LED the wrong way round. Best to use a Meter or perhaps a Torch Bulb (not LED). Another way if you have an old Speaker is to touch the speaker wires to the Circuit Board should give a buz. Crude but effective way to check power if you have no other means.
 
Running analogue:
You need a several volts on the track, before the lights will come on.
IF the loco has a decoder fitted:
It could be a change has been made to a CV. - You can set what function outputs (including lights) will be 'on' under analogue control.
It could also be, the decoder has been reset, and is giving full voltage out to the lights. - This may have 'popped' the bulbs.
If they are the screw-in bulbs:
They may just be lose in the holders?

if they appear black, they may just be old, and have failed..
 
It would sure help with a bit more info.

Is this loco equipped with a decoder?

Did it have front and rear lights working before? If both are out now, you can eliminate the possibility of burned out bulbs, both would not burn out at the same time except in cases of extreme overvoltage.

Forgive me for butting in, but there may be some confusion that needs addressing here. If this is the loco that Paul brought over to run at Hemsby on Sunday it has been converted to r/c battery power as he uses non-powered plastic track at home. So it's not your standard LGB track powered analogue. This may put a different light (forgive the pun) on the matter.
 
Yes as Mike say this LGB 20232 has been converted to r/c battery power (11.1v), it has front & rear lights which are directional. but thay don't work now. I have tried a 12v car bulb on the connectors & run it up but no light. photos of the loco inside & out.

Paul,
How are you getting power into the loco?
Are you feeding into the loco from a trail-car?
Have you lifted the wires off from track-power on the motor-block?
 
The power is from the tender 11.1v to the loco. No track power. It was all working fine then the lights & smoke stoped. The smoke works now but still no lights front or back.

If the power is from the tender, then check the batteries and cabling. I guess there is a connection between the tender and the loco that might need attention....

The battery has full charge, connection is OK as the loco runs with sound & smoke working well.

I believe the cable is a multi way one. Could be a single broken wire if it is just lights....
 
Paul, if I knew anything about r/c working I'd have a look at it for you, but I don't think my limited understanding will be much help. Just out of curiosity have you altered the lights in any way since you bought it?
 
Hi Mike, good to hear from you. No all is the same as it was set up, I just uninstalled the rail pick ups & connected it to a esc, RX & battery all was running well up to 3 days ago.

So, in effect, you are feeding the output of the ESC into the 'track-wires' of the LGB board? - Just two-wires into the loco from your RC gear?

If all else is working:
It has to be bulbs, or the circuitry supplying them, or a wiring fault from board to lights...

I wonder if the PWM output from the ESC has damaged the regulation on the board?
 
Yes, just 2 wires to the track pic up, the bulbs are fine but there is no supply from the light ports on the board. I have checked all the wiring & it looks fine. just no lights forward or back & no cab lights also.
