no power to fuse #15 '90 300se

The fuse on line 15 is good (I've tried several) but there is no power. This is the line that powers the antena, door locks, etc. I did have a wiring problem with the radio (aftermarket) but that is not on this line. Any thoughts? Thanks!

Joe,

Sounds like it's time to get out the ol' wiring diagram and start tracing back from the switches. Get a good voltmeter but as Deezel would say "Be careful when testing voltages not to short anything! The battery packs a wallop!"

Hmm... could this be a failed combination relay?? Check the conductors at the #15 position with a voltmeter. Ground the common lead, take out the fuse and check both sides of the fuse holder with the key on. If you don't show 12 volts on either side, start looking for a relay or a broken lead to the fusebox.. Also consider the possibility that the fuse holder might be corroded. Clean it up anyway.
