Hey guys, I have been away from this stuff for quite a while, so please be kind.  I have electrum offline wallet on a PC.  I have 4 wallets:  default, "mine", test1 and test2.  I can see history in default and test1.  Test2 had no activity so the history is blank.  When I sign in to "mine", electrum just goes away.  No history is displayed.  When I restore with the seed, again no history is displayed.  I know there are old transactions in "mine".  Any thoughts?  I'm on an old version 2.8.3 of Electrum.  What am I doing wrong?

I tried this method with electron cash wallet on android.  (I am traveling and didn't have another windows computer), and it DID NOT WORK.  Any attempt to sweep BCH into the electron cash wallet from the old wallet that I removed my Bitcoins from failed.  Because the electron cash wallet picked up all the transactions, including the ones that removed the Bitcoin and showed ZERO BCH balance.  I think there is a bug in the android electron cash wallet.  All the successful BCH recoveries that I have read about are for a PC electron cash wallet.

UPDATE:  THE EXCELLENT METHOD DESCRIBED ABOVE BY  Jpayne CLEARLY IS FOR A PC VERSION OF ELECTRON CASH.  THE OPTIONS AVAILABLE ON THE ANDROID VERSION DO NOT MATCH AND APPARENTLY ARE NOT AVAILABLE.

So, I guess I have to wait until I'm home and find another PC.  Unless someone has a methodology for Electron Cash Android.

Second update:  24 hours after I first tried android electron cash.  I had entered the seed into an android electron cash wallet, but initially it showed ALL transactions, including the ones that removed the bitcoin for safekeeping.  When I tried just now, those negative transactions were gone, my mBCC was there, and I transferred it to another BCC wallet.  Must have just taken time for the blocks to process.  All appears well.

 have BTC in Electrum wallet.  Followed their suggestions to split bitcoin cash and it didn't work.  I moved my BTC to a new "safe" wallet.  Downloaded Electron Cash to my android tablet, entered the keys to my old wallet (that then had zero BTC in it).  The electron cash wallet history showed both the positive entries and the withdrawal to my safe wallet, so net Bitcoin cash in the electron cash wallet was zero.  I don't see a way around this except to expose my safe wallet keys to electron cash wallet.  Am I missing something?
