It was a 10 fuse a mini with 2 prongs. There were 10 fuses in a line and I pulled 1 out at a time and wah-law ... blown.:)
So the scenerio goes ...... One light wasn't working. Removed the old one and began to insert a new. Bulb lit up but as I puhed it in the 2 hole socket the other 2 shut off as well as the new one (there are 3 inline). I had left the power on (possibly my mistake ... but it's the way I always do it to verify bulb is working). Removed the new bulb inserted another .... still none of the 3 lit up. The switch button is in a cluster of 4 buttons ... 1 for ceiling, another for ceiling and a spare. The 2 ceiling lites come on when switched. The sofa switch indicator lite comes on .... all four of the cluster switch indicators come on. Removed the switch plate. The switches are attached to a circut board and stopped there. Any hints???
