Hello My E300 will not turn the starter Its a 96 model with no electrics in the key the ign switch works okay and the car was running absolutely fine until only a few days ago. The first time it happened the ign lights came on but when you turned the key to start nothing happaned, no sounds at all. i checked the gear lever was in P took it out of P into N still nothing. I checked all the fuses and found FUSE 5 beneath the rear seats was blown. I replaced the fuse with a spare 30A and she started perfectly. The same sequence repeated itself a day or so later. Then the other day the starter would not turn outside the house, so i checked Fuse 5 which had blown again and replaced it but still nothing. Any suggestions?? I shall get a voltmeter on each side of the fuse i shall also try a voltmeter on the starter i looked up FUSE 5 to try to establish the fault and it seems the fuse operates the radio and the central locking? I replaced the K40 relay about 12 months ago but i will swap it back to check. any help appreciated. Alec.
