I need help troubleshooting this issue. The enlarger bulb will only burn at the warming rate. I have the main power unit, the Code ST1000N voltage stabilizer and the ECU 1000 control unit. I have checked all fuses and replaced the 1000wt bulb and socket. I have taken covers off the power unit, stabilizer and cord heads and find no obvious issues.
Backstory: I purchase the unit a few years ago and hauled it in a trailer from NJ to Ga. it sat in storage for three years. I recently installed it for the first time. The first time I connect everything and turned it on the lamp came on. I turn it off and flipped the head up to horizontal and the lamp then did not come on. I did not remove the top at that time and don’t know if was then burning at warning rate. The bulb may have been like that se in the socket, as I found evidence of some arcing and black carbon. I installed a new bulb and a new socket.
Any ideas on where to start?
Thanks!
