Tom,

What kind of 'test lamp?' Timing light, spark detector or 'other?' 
Connecting any neg. terminal to pos. gnd. would create a dead short; 
your test lamp must have enough resistance to prevent that (else you'd 
fry the wire and maybe your harness). The neg. coil terminal is your 
primary ignition 'hot' lead; points, if you have them, switch to ground 
(Pertronix would have pos. terminal permanently wired to gnd.).
