What should the normal amps output from generator at idle and then at 1/4 throttle be?
As measured at the output of generator?

I'm not a case guy.. but do know about generators in 'general'. Gennies do not produce power very well at low idle. My lucas genny on my ford 5000 will not even keep the discharge lamp off if run under 1000 rpm. My 8n needs about 700 rpm to make up 2-3 amp ignition draw plus charge at 2-3 amps... jump that to 900-1200 rpm and you can get 10-11 amps easy, Same with my allis chalmers genny.. 400 rpm idle and it is just making enough to offset ignition.. turning the 1 headlamp on creates a discharge... get to about 800 rpm and you get about a 4a charge.. and a bit more rpm and you can get perhaps 9-10amps....

Anyway.. I'd look for a very low charge or even just holding ignition draw at idle.. same with 1/4 throttle.. I'd think you'd want 1/3 throttle or better to get any significant charge or load capacity..

( alternators do way better at low rpm, by design.. )
