Headlights effecting running

[Bogeysride]

I just bought a 1989 Wrangler. It runs fine after it warms up, however,when i turn on the headlights or the interior lights it starts to sputter and shuts off. Any ideas as to what in the heck this might be?

could be your alternator starting to go bad ... also what is causing it to run bad when its cold ? choke or ? could be the place to start , and does it cut off like its a elect. short or sudden loss of carb action like rpms to low

It "hiccups" a few times, then shuts off like it may be an electrial short. The tach is broke, but the rpms do not seem to decrease. Hmmm?
