For MikeML,

V2 = 12 to 220 VDC input
V1 = 12 VDC from 12 Volt power supply
GND is common to input & 12 VDC power supply
Put it together and L1 energizes w/o input.
Problem my be using wrong Mosfet NTE2396.
It is N ch
Not a lot of selection here in Monterey
Thanks

Did manage to make something work.

4-150 VDC 2 wire LED Voltmeter. Buffer the 12 thru 220 dc input to fit within the meters 4 to 150 volt range. Put the meter in a little box along with a photo resister and bingo
