[Mgs] no start 77b

[aproudfoot at nf.sympatico.ca]

So I pulled my 77B out to have a go at the spring weather and I get no joy 
from the starter at all (battery is fully charged) all lights work as they 
should, fuel pump is pumping away. I am thinking the relay on the passenger 
fender could be the culprit? There are two, one for ignition & one for 
starter? I think? any idea which one is which? Anyone with the same 
experience?
Thanks
