And idea what the value of this resister is? It's the second one up from the battery..closest to the end of the board. I can't seem to find it on the schematics at the klov and it's burnt past recognition

Thanks!

Thanks!

Any idea what this diode would do if it fails?

I'm chasing a problem..the thrust is almost always on. I pulled the board and found the crispy part. Everything else seemed fine
 
That diode is in the memory protect/battery circuit. It does one of two things (I don't have schematics handy....and I can't remember which)......it blocks the batteries from getting a charge from the 5VDC line.....or it prevents the batteries from trying to power the entire 5VDC line, "routing" the battery voltage to only power the CMOS RAM when power is off.

Your thrust issue is, more than likely, on the small interface board.

Thanks!

I'm working on getting a different I-face board to fix the thrust problem

I'm guessing that diode isn't super important then if I remove the batteries? I was going to make a special purchase for it from BR..but maybe I'll hold off until my next order and add it
