Re: A-113 Not Working

2006-06-16 by ilanode

No, idea how likely it is that the module itself is damaged. I'm not 
good in electronics but doubt that a module with fried ICs can do 
harm to other modules thus I won't hesitat to give it a try. But I'd 
be very careful.
So, I'd (1) replace all blown fuses; (2) unplug each and every 
module from the bus board; (3) check the D power sockets with a 
voltmeter; (4) same with the connector; (5) tripple check 
orientation (-12V down); (6) connect only the A113 to the bus board; 
if that seems to work fine (7)connect further modules to check 
wether the A113 is working. I admit the (3) and (4) might be a bit 
overdone... I'm sure you'are aware of it, just to make the story 
complete: Some of the steps above should be done while the case is 
switched off.
Best luck, Ingo
