a couple of cars around here have had burnt out fuse boxes (well one is just a bit distorted) so they've wired them to be independantly wired / controlled - but both have seperate relays fired by the switch on the rad wires - power comes from direct from battery wires with independant fuses for each relay. Works a treat, especially if one is on a slight delay (if I recall correctly that came from an xr4x4??). I can check if you wish?

If you ask at Lucas specialists it was the fix they offered Fords from way back. I have some paperwork here if you are interested? One dealership for example had all their cars done to save hassle from owners who were frequently replacing fuses.

One guy at Donnington also has an overide switch on top of the dash for all that for those hot show days. You can buy the set up on one of the ebay stores apparently. Not spotted it myself though.

Makes sense doesn't it?
