Even though the reverse relay is clicking, are you sure it's actually 
doing 
its job?  The contacts on it may be burnt or damaged.  It sounds like you 
have no motor field current in reverse, which would be consistent with a 
defective reverse relay.  

Bill Gunn has replacement F/R relays which require a bit of re-routing 
wires.  It's not a big deal to do this.  Or, depending on which contacts 
on 
the F/R relay are burned, you may be able to  swap the FW relay for the 
F/R 
relay.

Don't try to reverse the E15 again until you check this -- you can damage 
things this way.
