Hi

Setting up my layout after 1 year hiatus. In process of debugging a strange problem is occurring and hoping for ideas.

I use a CS2 to power the freight line and a 6017 booster to power K83 (switches) and K84 blocks. The booster activates the K84 but the CS2 sends power to the block. I have run a loc to confirm no shorts. When I connected the K83 and K84 to the booster and then the booster to the CS2 the following would occur.
1. I activate turn out (TO) 1 and it worked. Then, with no action on my part, TO 2 would activate and then # 6 would activate (nothing assigned there but I can see on the CS2 keyboard screen the red dot move up and down). The K84 would also 'activate' the red dot would move or the current would turn on for various blocks (where this was assigned). In my prior layout, I had assigned TO to keyboard elements 1-28 and block controls (K84) 29-36. I have deleted all these and reassigned 1-4 and block control to 29-32.
2. I disconnected the K83 and K84 (fed no current) and the above did not occur
3. I reconnected the K84 and it seems (want to retest) the above did not occur.
4. I disconnected the K84 and reconnected the K83. At first I only connected TO 3 and 4 and above seemed not to occur.
5. Reconnected TO1 and 2 and above occurred again.
Conclusion: inconclusive but something with the K83 (wiring) is causing this random switching.

After I redo stes 2-5 I will trace wiring to the K83.

Appreciate other suggestions.

Thanks for the suggestions. I have not yet connected the S88, though plan to. I have deleted some of my prior memory entries (have quite a few from my prior hidden yards). So, will delete the rest and retest. Not sure what you mean by floating or upside down ground return (the T?).

In further testing last night, I found Keyboard TO1 and TO3 create the odd activity in the CS2 but not TO 2 and TO4. Not sure if this suggests a damaged K83 but I will test that as well by replacing with another K83.

Will be travelling for a few days and will test further on Monday

Exactly! The question is why.

Yes it is possible that the s88 support logic inside the CS2 is fault, however it is far more common for an external event/wiring to be the cause.

You state "... I have not yet connected the S88 ..."

Can you be specific and complete with this answer.
a) is a s88 connected to your CS
a i) are there loose aerials - wires connected to the ports but not connected to the layout
a ii) is the grey cable connected correctly
a iii) is there a ground return connection plugged in, AND which power boundary is it connected to - ensure it is the Brown and not the red
a iv) is the grey cable damaged.


Have you set up a layout page with all your sensors added for debug purposes

OK, so no external s88 triggers,

Had you ever set up a Locomotive function to link to a Route?

If you have access to your CS2 over the network you could look at the http://xxx.xxx.xxx.xxx/config/lokomotive.cs2 file with your browser and search for "..fs="
