i recently aquired a hgm-5. it has not been converted or modified as it came from the medical field. i did not get any manuals or the foot pedal. i found a post regarding the wiring of the "din" style plug for the foot pedal. because i did not have the mating din plug, i carefully followed the wires from the din plug to the amp connector, writing down the crossover from one plug to the next. i cut of the din plug and connected what was pin 2 to pin 3 and added a switch between pin 3 and pin 7 to ramp up the tube. the information i got also said i need to connect pins 12 and 14 together but those pins are not even used on the din plug, they don't even have wires attached to them. i powered it up for the first time tonight and cannot get it to lase. all the readouts are functioning, the unit powers up, fans run, i have one of the fiber cables inserted, there are 2 red leds lighting on one of the power supply boards. there is a red led marked "plug" lit on the top of the "dose" board, what does this mean? i have obviously pulled the case interlock up, don't see any lighting at either end of the tube but do notice a slight smell of ozone near the open chassis. the power indicator lights up, the standby indicator flickers and then comes on steady. at the same time, the dose light comes on steady. pushing the standby button does not turn off the standby indicator and the dose button doesn't seen to do anything. there is a slight (very) possibility that i may have messed up on the wires from the old din plug (late night last night). does anyone have the wiring schematic to cross-reference from the din plug to the amp connector? thankx in advance for any help you may be able to give me.....mike
