AMS DMX 15-80 card question

[mrzoo]

Hi,

Have some problems with an AMS DMX 15-80 where the device gets really hot.
I think one of the cards loads +5V too much.

I have checked all the cards between +5V and 0V and the dmx27 called mcb4 card might be the problem. It has 46ohms between +5V and 0V.

Or might it be correct value?

/Peter

You could have a faulty tantalum cap, very common on AMSes.
