Put a different 340 xenoah motor in my 76 340 nitro, ran fine but no lights or tach. I replaced the stator as i had an extra one, I now have dash lights, side markers, and tach but no tail light or headlight? Replaced both headlight and tail light bulb,still nothing. Would a voltage reg cause this? CDI? or wiring issue? Thanks

could be a key switch, could be the circuit board also. probably not the v.r. because if the v.r. is bad all the lights will blow.i would look more to the electric side of things more than anything,.....

Key switch was new a few years ago but could be. What about the headlight switch?Do those go bad?

Sometimes the hi lo headlight switch can go bad but haven't seen one break, does it click when u flip it? Is that wire hook up right on circuit board? Circuit board should tell u which plug is for. Make sure All the wires connected properly, u can tell the voltage regulator working if the light stay good level of light at idle and if you rev it up to 3 or more rpm, if the light on dash goes really bright then you know the vr is bad, if still same or dim down just little bit then it's working fine. If have no luck then sounds like ur circuit board might have cracked in it.

The headlight plug has no power going out of it so im leaning towards the circuit board being bad.

Are you getting power to headlight switch?

You should get a pen with sharp point with ground alligator mouth volt tester so u can poke thru the wires to see if the pen lit up
