Blown bulbs when switching on
Hi: Having an odd problem w/ light bulbs blowing across 3 circuits with no dimming or brightening. When switch is flipped on, bulbs immediately fail, one actually made a small "pop" sound--6 in all in one week. Also had reverb on computer speakers.
Basic Info: 80 year old house; all new wiring except for livng room run on knob and tube which is tied into one of the new circuits. Power company check states no loose neutral on their side. Have lived in house 30 years w/ no problems until last week. Have been told a loose neutral would cause brightening and dimming, and since I don't have those symptoms that I don't have one. Knob & tube in unusually good condition.
Looking at other posts I discover info about shared neutrals and flourscent lights--I not only have fluorescent fixtures, I use flourscent bulbs in regular lamps.
Complications: Am awaiting roof repair due to termite damage plus a leak at an exterior wall where the knob and tube feeds an exterior light on sun porch.
Question: If the knob & tube got wet could it affect the rest of the circuits? Could the termites have damaged the newer wiring? Any other comments would be appreciated.
Thanks--Wrenwell
