You should just have two fuses on a std setup, regardless fuses only blow for one reason, excess current, this can be a couple of reasons, too much load, ie you fitted night blinder spotties, or a kickass stereo, or you have a short. If you haven't fitted anything, you will have a short, a common one is bulbs, especially brake lights corroding, but it could be anthing shorting to ground, fuel sender, dash wiring loose, a screw through a wire, unfortunately it will be trial and error to find it, be methodical, replace fuse, check one system ie lights see if fuse blows, and move to the next, it shouldn't take a couple of hours as morry electrics are very simple

when does it blow ie:when you use the wipers ect ?as there must be a short in the system or a jamed item[wiper motor]try to isolate which operation is causing the problem,if it blows as you turn on the ignition whith nothing switched on you have a short to ground in main power circuit,maybe a jamed/bare wire going to earth,when did it start hapening?

Thank you. it only started this morning when i was going for a drive. I came & had lunch then went back to start from lights & I think it was the fuel sender. I pulled the spare tyre out & looked around but nothing unusual. OK at the momem. Yes I only have two fuses it is the one that goes between 3 & 4.

On a standard Morris Minor, that fuse feeds the fuel gauge, windscreen wipers, stop lights and trafficators (if fitted). I think that the last one to look at would be the fuel sender as a short there would only cause the fuel gauge to read hard one way all of the time. Wipers and stop lights greater suspects.

Ok. Looks like I had better look at them & see what is wrong again.
