So it would appear that the diagrams on pgs 1-33 to 1-36 are the correct 
ones for my machines?


It feels to me like the fwd rev relay is getting switched but has no 
current to its contacts

There is no current draw according to the gauge

There's a GOOD reason for that. E-12 S &amp; E-15 AA to GA don't HAVE an 
RTN 
relay. The RTN functions are contained in the silicon skulduggery on 
Card #1.
