We have had quite a few new owners joining us recently and it may be worth pointing out that there should be a spare 15 amp fuse in the RH side of the battery box as shown in the photo below.
It is the only fuse on the TTR and the one in use sits in a holder that clips into the top of the battery box as can be seen in the top middle of the photo below. I am re-using a photo so ignore the yellow arrows!
