Burntgate - The cutout relay will drop out ONLY when the generator voltage drops lower than battery voltage - ie. at slow idle and when the engine is shut down. Can test by watching the ammeter. From idle slowly increase the RPMs - the ammeter hand should suddenly "snap" from a few amps of discharge to 5 - 10 amps of charge when the cutout pulls in. Conversely when slowing the RPMs down, as they approach idle the ammeter will briefly show a fairly substantial discharge (like 8 - 10 amps) then immediatley swing back to a couple amps discharge when the cutout opens. And at shutdown down the ammeter should indicate exactly 0 after everything stops moving. ---- If the cutout doesn't pull in above idle RPM, the spring tension is too HIGH. And if it remains pulled in at low idle or after shutdown, spring tension is too LOW. If you must adjust the spring tension do it in smallest increments possible. Cutout relay spring adjustment is very sensitive as you will find!!
