No Fire on 87 D21

[mattlyon]

My 1987 D21 (z24-std transmission) Quit the other day. Found that there was no fire at plugs. Have checked coils. Both have Battery voltage. Resistance fine. Have one Black wire w/red dots plugged into side of distributor. No power here at any time. Key on or off and while cranking engine. Need to know how much voltage should be here, whne itr should be here and where it comes form. Have traced the wire into dash. Am about to take dash apart to continue investigation. Haynes manuel incomplete on this subject, local mechanics baffled. I know there has to be power to this point but do not want to put jumper here until I get further info. Please help!!
