Hi all,

Just wondering if anybody has added an external capacitor (not a Massoth power cap) to the current version of their digital light bar? The manual says it needs to have an electrical strength of at least 35v. I've just tried adding a 35v 3300uf cap to the connects as per the manual and all I get is weird flashing/strobing of the lights... Remove the capacitor and all returns to normal. Wanted to try this on the light bar before I added a cap to the 8 function mini decoder in my other coaches.
 
Are you *sure* you have correct polarity, and connection points?
 
The more I'm thinking about it, would it make more sense for the cap to be on the Dec+ and Dec- connections like if you were using a Massoth power cap unit? I've not seen the Elko+ connection on any other decoder before.
 
It's hard to see what the Elko+ pad is hooked to:

You could call or email Massoth?

I know Peter is no longer there, but I have heard good reports of support being a lot faster than in the past.
 
Thank you! This is relevant to me as well. What about slapping a small resistor or choke on it to limit inrush current, with a diode t'other way for output?
 
Any update Andy? - Original Poster..

One other thought...................
There are many 'effects' on the lighting options in the latest decoders.. None of these are turned on, I suppose?
