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.). <br>

<div>BJ8--positive ground-------test lamp hooked to negative of
coil (engine running) and then to ground. Light lights but
this shuts down the engine. Should it? If not, any idea why
it does?</div>
