Only registers full voltage when there is a relatively large draw on the power. 5kva diesel generator, needs to have a power draw of 700w plus to give full voltage of 220v.
When nothing is connected indicated voltage drops to zero and generator will not switch itself off on key (electric start).

I am sorry I forgot what the 1000 stood for. It has 3 sizes of plates or what ever you call them I only need instructions for this one task Thank you
