Still having to manual start it. I've replaced and checked everything i think. From the bulb to relay to diode to ignitor...checked voltage i thought everywhere. adjusted and switched out the ignitor trim pot....however at that last step...i checked the voltage going to the pot...there was none! i think i might be finally getting somewhere but alas i have no idea what feed the volts to the pot....any help would be greatly appreciate...or any other ideas you may have, that i might have overlooked...  |  IP: Logged James Westbrook Phenomenal Film Handler Posts: 1133 From: Lubbock, Texas, Usa Registered: Mar 2006 posted 10-04-2009 01:21 AM                     Check the wires to the resistor, the long cigar-shaped ceramic thing mounted in the power supply.
