Ahhh yes, I have been there bro. The points constantly arc as the kerosene flow is controlled by thermostat and water movement (flow switch). And if the arc doesnt happen , kerosene still moves into your coil housing and starts to build a bomb. Then when the points finally arc, you have black smoke ROLLING out of your truck and sometimes flames shooting out of your exhaust. When I turn my heat on , I know to listen for that arcing buzz before I even try to heat up.The kerosene would keep adding fuel, then the ignitor would fire intermittently causing the excess fuel to ignite violently.
But, it will heat......alot.
