Firstly as this is my first post, a sincere thanks to all the contributors here, many times the advice and knowledge here has been a great help.
My Cl. 31 (6 pin PCB) has now had 2 PCB failures on DC, the most recent of which was with a brand new PCB spare purchased from Bachmann. Although purchased in 2016, this loco has run for all of 5 mins, literally.
Bachmann has refused to help me, stating that spares aren’t covered by warranty, despite the PCB arriving here in Aus with lighting wires which detached from the PCB upon opening the bag!
I’ve traced the fault to what I think is Diode D3 on the PCB as the loco will run in direction A only with forward lights and no rear lights. Direction B I have no movement and no lights at all. Testing the PCB lights with my multimeter, both PCB mounted lights are functioning.
I think I might be able to resurrect this PCB if I can replace diode D3 as this diode is displaying zero ohms resistance. But I’m happy for any guidance you can provide on what I should be testing on the PCB and how to test it.
Given Bachmann has taken my money but refuse to help me, I’m not too keen on buying yet another spare as this PCB seems to be very flaky. I’ve many other Farish locos up to 10 years old that run just fine.
Does anyone have any advice as to what specification of diode I would need to source if D3 is the culprit and how I might go about desoldering and resoldering it.
Apologies if this question has been asked/addressed before - I did have a good search before committing to join and post.
Thanks in advance to the community for your kind assistance.
All the best
