inobu Posted March 17, 2021 Share Posted March 17, 2021 Look for heat or scorching. You said you smelled something. Either it is the pick ups or light board. Link to comment

The smell came from the powerpack after the whole system shut down when the faulty motor car was on the rails, and the speed turned to maximum and the powerpack shut off. I reset the powerpack and everything turned normal. I noticed a very slight heating from the power bogies I think. Link to comment

inobu Posted March 17, 2021 Share Posted March 17, 2021 You need to check the light board. The power flow is track to wheels to pickup to board Link to comment

disturbman Posted March 17, 2021 Share Posted March 17, 2021 If the lightboards are faulty, shouldn't the short be replicated by just putting the lead cars on the rails, without the motor car? If there is heat in the power bogies of the motor car, the short is probably happening there. Not the lead cars. Link to comment
inobu Posted March 17, 2021 Share Posted March 17, 2021 The light board also feeds the motor Link to comment

This is not the case with mine I guess. Link to comment
inobu Posted March 17, 2021 Share Posted March 17, 2021 I'm using the light board term loosely. The board that feeds the motor Link to comment

I mean, literally taking them apart. Link to comment

inobu Posted March 17, 2021 Share Posted March 17, 2021 Does that motor car have lights in the roof? Link to comment
Daniel C Posted March 17, 2021 Author Share Posted March 17, 2021 @disturbmanI think it's not the bogies. I removed the entire motor unit and only attached the bogies and nothing happened to the powerpack or the leading cars. Link to comment

disturbman Posted March 17, 2021 Share Posted March 17, 2021 I didn't meant the boggies, I meant the motor car. Metal is very conductive to heat. Link to comment

inobu Posted March 17, 2021 Share Posted March 17, 2021 ok, its the poor connection that is drawing the high current. Link to comment
