A 120v heater running at 40v will only pull about 11% of it’s rated wattage.

Ok after much wrench time a few brews and some help from a buddy.. this is what I have come up with.. hang on here we go. I dismantled the Gen unit of the 600 and looked at the pole shoes and made a note of the resistance on the shoes all four.. I then pulled the Gen unit from the 752 and the 8C3 as well and made some more resistance tests along with induction tests. I only came to this idea because in one of my books on the 8c3 and 752 units Delco had given an updated set of pole shoes for replacement in the feild... Guess which set I found lurking in my 600 watt unit.. a set from an 8C3 800 watt unit right down to the acme wire tags and resistance values.. So how does this change things.. the combo light plants have a automatic throttle to control speed and amps.. the 600 does not.. I will post the note for the updated feild poles for others to ponder..

Hopefully the picture uploaded.. anyhow, hope the holidays treated everyone good.. after much debate and lots of wrench time I have found that my current normal operating voltage for that engine is going to be just a little bit higher because of the new pole shoes inside. I have put in a screw in heater in line with the batteries in order to reduce the voltage down it is just a little blip but it does make it much more manageable please also remember that with the 600 series of light plants there is no automatic shutdown it has to manually be shut down there is no drop off once the battery set of predetermined value it will keep going until everything boils out I've got more information on that which I will upload as soon as I get a chance to thanks guys for all of your help and I got an early Christmas present there just so happens to be an 850 sitting in the shop now more on that later thanks for all of you guys as input

If you’re handy with a soldering iron, an LM393 comparator chip, a zener diode, a transistor and some resistors will let you make a voltage level sensor you could use to trigger a relay when you reach some set cutoff voltage. You can build your own voltage sensitive auto shutdown this way. The circuit is in the datasheets for the chip, or if you’re interested I can sketch it for you and post it here. Easy and cheap.
