Hi

Got my first mini yesterday, its a 1989 mini city. The fuse box as been replaced with a blade fuse box with 6 spaces.

Managed to blow a fuse i think by turning my main beams on. Now have no headlights or cd player either ( cd player might not be related my little brother was fiddling about with it). Anyway all the fuses in the box are 10amp. So i'm assuming i need a bigger sized fuse for the blown one?

Should all the fuses be 10amp though? Seems a little strange to me.

Sorry if this is a stupid question but im pretty clueless and my dad's fiddling just led to another fuse being blown.

Thanks for the help.

NO - some of the fuses need to have higher ratings than 10 amp, off hand I cant advise what each rating should be, but it might be beneficial to get professional advice by auto electricain or AA geezer if your in, to get ratings correct otherwise they will just keep popping.

congratulations on the purchase, and hopefully its just teething problems that you'll get sorted real easy

I would imagine they have replaced the original 4 fuse box, and the 2 inline fuses on the bulkhead, with the 6 fuses in this new fuse box.

The best thing would be to remove each fuse in turn, and see what doesn't work when it is removed. For example there is one fuse that should cover the brake lights, reversing lights and indicators. When you find this fuse, check in the Haynes manual what rating fuse should cover these circuits.

Off the top of my head, mine is 35, 15, 15, 10 from top to bottom I think.

That's no help to you but it confirms that they are not all supposed to be 10's.

My wiring diagram for Minis with dim dip relays can't be right as it shows no way of powering the main beams but it does show the relay with two power lines: a permanent brown/orange with an inline fuse and a green supply off the ignition switch via the fuse box. Useful for fault finding.

Remember blade fuses are marked with their fusing current so a 20 Amp fuse would be about right for 2 headlamps and 6 x 5W of side/tail/number plate lights.

Amps= watts/volts

so for 2 x 55W headlights... 110/12 = 9amps continuous (near enough), double it to get the current the fuse should blow at.
