Problem with my lgb nicki franks

That's not what I would call a standard multimeter, it's unusual to have AC amps that high. List price is about $200 here...............

My own digital multimeter, which is a Rapid own-branded one, a slightly older version of this one:

Rapid RHMM17 Digital Multimeter

Rapid - RHMM17 - Rapid RHMM17 Digital Multimeter - <P>The Rapid RHMM17 digital multimeter has a highly versatile selection of ranges covering AC and DC
www.rapidonline.com www.rapidonline.com
also has an AC Amps scale up to 10A, just like Adam's one - and is under twenty-five quid including VAT; that's why I described it as pretty much "standard" for modern digital meters, at least over here....

So this morning I did some more testing when the loco cuts out there is no increase in amps draw. After I ran the mallet and the readings are almost identical.

Back to the problem in hand, would appear from the OP, that motor control appears to be normal and possibly not the root cause for the shutdown.

Touch of detective work...turned up these.........

SOLD: LGB 20261 Rugen 0-6-0TT inc motorised tender with DCC, sound and OVP - G Scale Central

LGB 20261 Rugen 0-6-0TT inc motorised tender with DCC, sound and OVP This is the first and oldest version of this loco. There have been at least six other versions since. The original is DC only with two motors, directional and cab lights, and a smoke generator. I have fitted a Massoth XL...

Digitising LGB 20261 Nicki-Frank-S steam tender loco - G Scale Central

Post 30, caught my eye, with particular reference to the details on the smoke unit, and using the info from this post, applied this to form the table below...

Using the Lenz LZV100 as a reference point, then recompiled the table below...

Does seem to indicate that from the above tables, the CV55 setting and the A1 output may require further investigation....

That post of digitizing the franks is my loco I bought it from idialmarvel

Physically disconnect the smoke unit and test the loco again. Switching it off with the controller may be insufficient if the output is configured to a different function than expected or if running analogue when the output is configured to be permanently on in analogue mode.
 
I think disconnecting the smoke unit would be worth trying, you may have inadvertently turned on the smoke unit (F7 I think from memory), although the current draw would be much higher if the smoke unit was on.
 
Adam, just wondering.... when the loco cuts out, have you felt the underside of the gearbox to see if it is unsually warm?
Not sure what it would necessarily indicate even if it was, but it was just a random thought!

Jon.
 
I have already tried that I thought maybe it was starting to seize up or draw to much it might get hot but nothing, I ran it with the body off earlier to check if the decoder was hot when It stops as well but all was okay.:banghead:
 
Off the wall thoughts.

Only this one loco? - So 'something' on this one.

Loco only? - So tender OK.

?? Is there any sort of inactivity timer function on this decoder ?? - I do not know of one. ??


Adam, Have you a 'spare' motor? - Could you connect the wires which go to the 'block motor pins to another motor? - Proves (original) motor is OK, if still a fault.

So only this loco only but the tender motor stops as well and all the lights go out

I am assuming that the electrical connection between loco and tender is by way of a six (or more) way cable and plug, as it should be carrying power from the tender's pickups (2 wires), power TO the tender motor (2 wires) and finally power to the rear lamp on the tender (2 wires). If you could jury-rig a dummy plug to connect the pickup wires to the motor wires, the tender should then run solo on DC for testing purposes. In normal operation, of course the tender motor (and lamp) is being fed from the XL just as the loco's motor is, so it will stop if something is shutting down.

No Jon it has 4 wires between the tender and loco, there is a function decoder in the tender to control the lights on the tender. (I know this as it was my loco before I sold it to Adam last year).

Adam, unfortunately I think you have got to the point where all avenues have been explored and no-one has come up with an explanation other than the XL decoder is likely the problem.

Hmmm, that is very interesting, Dave, and might be in some way relevant to the problem - Adam, you mentioned that when the loco shuts down, the lights go off (though the sound doesn't, as it is a separate module) - does that definitely include the light on the rear of the tender?
I'm just thinking that if, as Dave says, the tender lamp is run off a completely separate decoder - then surely (if the problem is in the XL) that should be staying on in the same way as the sound system is.....?

I don't know how or if that actually helps at all, in fact it probably just complicates things even further.... :wondering:
