Temp gauge fuse- which one is it??

[sapper]

Just change the temp sender and think I must have blown a fuels as now the gauge does not move.
Checked connections and had a look in the bible and there is no reference to the fuse.
Anyone know which one it is please?

Do your other gauges work? I think it could be a common fuse.

All other gauges work work and so was this one until I changed the temp sender. Its not the sender. I've tried the old one back in and no change.
