1.  Should anything happen when I turn on the key? - i.e should any of the
relays click? Should the gauges show the charge state?
    first get the main disconnect turned on.  it needs to be pushed in and 
turned to stay on.  its on when the fuel gauge reads battery level.  on 
some of 
my machines, there is no audible click when key turned on.  other machines 
have a definite click.  
 
2. I've found the seat and brake safety switches - are there any more?  no
 
3. When I press in the 'Disconnect switch' The gauges do show the charge
state and resistor elements get hot (nothing connected to the PTO). Is this
normal? Should the PTO contactor click? 
    large resistors above charger should not get hot when key turned on, 
only 
when throttle pedal is pressed as in the first few speeds.  yes pto should 
click on and off.  
 perhaps your foot pedal is stuck in a depressed position, causing 
resistors 
to heat.  

4. When I attempt to charge - with the disconnect out nothing happens
(except the transformer hums). with the disconnect in the resistors get hot
as before. Is this correct? (I can't see any change in battery voltage but
also can't believe the resistors should get hot during charging).
    main disconnect must be on for proper charging.  resistors should not 
get 
hot when charging.  it may be difficult to see increase in voltage on new 
fully charged batteries when charger is on, especially from a weak 
charger.  but 
generally when charger goes on, fuel guage needle moves to right 
immediately.
 
5. Does anyone have a circuit diagram for the E20?
 
6. I assume the large contactors are part of the motor speed control 
system,
but what is the function of the relays at the top of the plate (behind the
switches)?
 
7. How does the cruise control system work? - is this the function of the
PCB's and components.
    cruise only works when foot pedal is in right speed.  usually this is 
the 
4th speed, and blue light on dash goes on, telling u you're in that speed. 
 

    i've only answered where i have some knowledge, others will hopefully 
fill in.  try putting transaxel in neutral and running tests.  when all 
systems 
are go and nothing happens, ive had luck in hand spinning the motor to get 
it 
started.  something like jumping a standard shift car.  but watch out for 
fingers getting caught in pully/belts.  good luck, jon k albany ny
