Clyde's CS Power Module

Postby barmagan » Fri Oct 24, 2008 1:16 am

We have 2x CSK-FM430revC modules. When we connect the Clyde power module to the FM430 batteries get very hot. Both of the switches are not connected. We didn't experience this problem with the other FM430.

What can be the problem with the FM430?

if the switches are not connected, then battery ground is floating, and the batteries are not connected to the outputs. So I have a tought time understanding how that could be.

Did you perhaps connect them with the pins "off-by-one"? That would certainly cause problems.

We connect the EPS to Rev C Dev Boards and Flight Modules here regularly, w/out issues.

It's probably worth probing the 104-pin connector (H1 & H2) on the EPS and the FM430 to look for shorts. Each FM430 (and Dev Board) is functionally tested at the factory (although S0-S5 are not tested).
