Junkyseb Posted October 28, 2005 Report Posted October 28, 2005 Hello, I need some help for my MF module.I don't have 4v at C4. My wall power supplie give 17V but when I plug it into J1 I have 4V at the bottom of J1 and I have 2V between + and - of the bridge rectifier... Is it normal ???Thanks for your help Quote
TK. Posted October 31, 2005 Report Posted October 31, 2005 Hi,no, this isn't normal. Sounds, like there is a short circuit somewhere at the board?Are all ICs and connections to motors/core module removed when you are doing this test?Best Regards, Thorsten. Quote
Junkyseb Posted October 31, 2005 Author Report Posted October 31, 2005 no IC are in there socket and faders are connected ! Quote
TK. Posted October 31, 2005 Report Posted October 31, 2005 Please disconnect them all when measuring the voltages - so long the MF module is not controlled by the core, the 74HC595 drive the faders into random directions (or not... or anything randomly happens)Best Regards, Thorsten. Quote
