NOTE that in some cases in MG F cars, when Heated Rear Window relay (HRW) is not mounted (for example there was no hard top when leaving factory), relay base does not need to be present below two other relays on the right hand side of the fuse box (Window Lift Relay and Engine Bay Fan Relay) as per picture below:
Relay base can be tucked away behind fuse box and need to be searched for (on next picture you can see HRW relay base with yellow HRW relay mounted behind fuse box):
I was not thinking straight, (another story) and put the battery in the wrong way round, now the battery light is on permanently, would it be this fuse that's blown, everything else apart from the radio works although not checked the alternator output yet
Thank you Roverlike. My 2003 TF steppy won't start (it's not the battery) and I hope I can find a solution in the wiring. Possibly a wiring problem or maybe the starter relay which I didn't know existed.
