The heater blower is a current hog.EDIT: just turned the heat off and now it does not miss or hesitate, what gives?
There should be a ground wire from the battery negative clamp terminal to the inner fender. Make sure that yours is there, that it's connected and not rotted. For testing, you can also use a single jumper cable to connect the negative battery post to clean metal on the body someplace; if the problem goes away with cable connected, then your body's not grounded properly.
The blower can also get wire rot at the blower motor connector and at the resistor plug connector, which can increase the already high draw when the blower's on.
And I think that there's also a ground strap from the engine block to the firewall, which usually has been disconnected over the years.
