I have a Meteor with an Alltek lamp driver board it is fully led'ed however a few still flicker.
The rocket 1to7 and the specials on the left flicker.
If I put a resistor across them I can make them work normally.
My question is, is this acceptable with an Alltek board, am I likely to damage anything.
It would appear that this sequence of LED's needs a little more current to lock the scr's.
I wonder how low I can go with the resistors to achieve the required result.

Thanks for your quick response.
I can measure the voltage in the morning, but can you tell me what I am looking for. All the rest of the lamps work fine except for these 9 lamps.
Would the wrong/ low voltage cause only a limited number of lamps to not work properly?

Couldn't wait, 5.4 volts and all connections are very clean and sound.

Thanks for the replies, I tested with a 1k, and a 560 ohm, both work fine. Probably need to test and check how the board is running after a while. Wouldn't want to damage anything.
will try and measure the resistances on the Alltek board.

My board is configured correctly to run LED's.
I queried with Alltek and Dave has kindly offered For me to return it for testing at postage cost only, so I could do that.
However As there are only 9 lamps flickering I might just take note of barakandl as posted above. 10x 560 ohm resistors cost 55c as There don't appear to be any "don't do this" comments.
Will test it out and keep an eye on the board. Will also report back if any issues occur.
