(ET) trouble...she no go

["e s" <stupidemail5 lycos com>]

So i replaced the fwd/rev relay and it ran just fine, plenty of battery, 
no worries, just no brakes.

fixed the brakes [note, stupid placement of caliper, 1/2 inch different 
and it would be a 2 minute job] 

Now she no go. Fwd rev relay clicks back and forth, but no power drain. 
PTO lights lift all work

Have manuals but haven't deciphered the troubleshooting diagrams. Part of 
the problem is lack of  labeling on the machine 

jumped out the brake and seat switch to test. no dice

hints welcome................
