the load control relay is the white one, the headlight relay is the blue one. i guess i go about a differnt way of finding a problem. never was into just throwing parts at a sled, so unless you just want to spend a couple hundred on a stator i always like to find out what the problem is. The load control relay is able to be removed and it deletes the wiring of the sled out of the equation, it will let the ign system work alone, if the sled still stalls then yes, it would be power related like the stator, if it runs fines then theres an issue elsewhere with something shorted out in either the light system, meters or wiring.
I have seen sleds have that problem that someone installed 80/100watt bulbs in, the stator can not supply enough power for the ign and the lights. That one took a few times to figure out what the problem was, who checks headlight bulb wattage....lol
