Re: Reparing half-nut 41CV Message #3 Posted by Randy Sloyer on 12 Sept 2003, 7:48 p.m., in response to message #1 by Tracy Vermeyen
The first thing to try is a "master reset". Short the leads together for a second or so of the 470uf (the largest) cap on the left side of the board and retry. Many times the processor will be in la-la land and will not respond otherwise.
If that doesn't do it, Tony's suggestion is spot on. The current consumption will help with a fault finding direction. If it powers up with a direct connection to the diode and capacitor, it is most likely a broken trace on the battery connector. This usually happens only with a battery leak.
Normal operation will be between 30 and 50 ua, standby will consume about 1 ua.
My money's on a master reset. Half-nuts are pretty darn hard to kill.
