Slot.it Scp02 Broken (My Fault) | Next Steps?

[miveson]

Whilst adding power to the rally track I had the slot.it SCP02 wired up correctly and it was working perfectly as I wired up each section.

 

Section 1 - all good

Section 2 - all good

Section 3 - all good

Section 4 - no good

 

I looked up and saw both the power supply indicating a warning (normally means the rails are touching or something similar. As I looked up I saw the lights on the controller panel flicker green and then go off.

 

Kicking myself for having the controller wired up in the first place. I suspect that I did something wrong with the wiring on Section 4 that probably caused a short.

 

Now when I wire up the controller all that happens is that the area around the cartridge gets very hot and it obviously doesn't work.

 

Any tips for determining what needs to be fixed on the controller?

 

I suspect that I'll have to replace the whole thing but if there was anything I could do to determine where the problem is. I used the slot.it wiring instructions which indicated as follows:

 

WHite/Yellow = Negative

Red = Postive

Black = Track

 

I would have thought that the fuse would have protected the electronics.

 

Any help appreciated - currenlty using some rather old Parma controllers to test the rally track

I reckon you've got you white/yellow and red arse about.

White is positive from supply, red is negative from supply and to track, and black is positive from controller to track.

 

 

Fuses only protect against shorts, not incorrect hookup.

Yes - you are spot on - sorry the writing on the slot.it instructions is so small.

 

White/Yellow = Positive

Red = Negative

Black = Track

 

Same result either way - a short when connected.

 

Thanks for the advice.

The fault is most likely in the cartridge.

It may be repairable, but thankfully, even if it's not, a replacement cartridge is significantly cheaper than a replacement controller.
