Scotty gave you the link to my long winded but complete test procedure, but heres short answers to your direct questions:
The next question is how can i tell if the gen is outputting simply?
Place a voltmeter on the battery, if its a 6 volt battery it should read around 6.3 volts (twice that if a 12 volt) just setting there tractor not running,,,,,,,,then when she is runnign at fast RPM IFFFFFFFF the charging system is working,,the battery voltage should rise to the 6.5 to 7 or a lil over range (twice that on a 12 volt system) ..If it never increases battery voltage, shes likely NOT charging..
can i read with a ohm meter at the gen?
NO you need a voltmeter
if so which contacts?
The gennys output is measured from its ARM post to case ground
The wiring is new and known to be proper but i dont know if the switch, relay or gen are to blame.
See Para 5 of my Troubleshooting Procedure to see if non charging is a generator versus a regulator or light switch type of a problem.
If you jump the gennys FLD post direct to case ground she ought to max charge so when shes running at fast RPM momentarily short the gennys FLD post to case ground n see if she charges then (ie see if battery voltage rises and/or ammeter shows good + charge). If so but NOT otherwise, the genny is okay so the problems in the light switch or its not grounded or the wires open from FLD on genny up to light switch........ If dead grounding the FLD post dont make her charge, leave it grounded when shes running and temporarily by pass jump around the cutout relay by connectign its BAT terminal over to its ARM/GEN terminal n see if she charges then????? If so but NOT otherwise the cutout realy is bad or not well grounded. If theres still no charge with FLD dead grounded and the cutout relay by pass jumped, sounds like the genny isnt charging
Check my procedure that Scotty posted for more detail

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
