Title: DCC EZ Command Module Intermittent Operation
Post by: ggerue on October 29, 2020, 01:39:32 PM
Greetings;

Intermittently my controller will default to position one when operating locomotives in positions 2-7.

Only happens when locomotive enters a switch. Not specific to a particular switch.

Suggestions?

I haven't used the EZ Command for a number of years, but I think it reverts to position 1 after a short. Is it only happening with locomotives with a long wheelbase, or with only 1 locomotive.

More than one locomotive, but am slowly isolating switches with this issue. It appears to be a short, but only lasts a moment and if module is reset to desired slot, operation resumes. Found one locomotive where the hose part of coupler was catching the frog and creating a short.
Appears to perhaps be a design problem on my part and I will hopefully correct as time passes.

Do you have a coupler height gauge? That was just discussed in a nearby discussion.

Great solution. It can solve some issues.

The trip pin "hose" hanging low is common for all knuckle coupler brands. That's why, as others have mentioned, having a coupler height gauge like the Kadee #205 or #206 is one of the basics for the tool collection. The shelf below the coupler in the pic is for checking trip pin height. If it's off, a pair or roundnose or needlenose pliers makes adjustment easy.

I prefer the insulated #206 because you don't have to worry about shorting anything out if the power is on.
