Re: (ET) e12 wierd problem

[Christopher Zach <czach computer org>]

Loose wire or (more likely) misaligned relay points. Take a good hard 
look at your 1a and 2a relays. My guess is one of them is dirty in the 
closed position and sometimes doesn't conduct even though it's "closed".

If you touch the relays, use a small wooden pole. They can shock you if 
the motor shuts down quickly.
