Excuse me for jumping in , You say lights are dim for a bit after you get it started? more then a second or too? you may want to have your alt checked (regulator checked )I believe its internal on that one ,a diode may be bad causing a drain on ignition source(going to ground )witch would or may cause such a problem , starving coil from power ,How is it on warm start up ? do things act the same way ? The dimming of lights is normal during cranking as most power is put towards the starter, Its after you let the key go im asking about ..........just trying to help
