I read in sci.electronics.design that DaveC wrote (in
et) about 'Amp's
power MOSFET died. Can I just remove it?', on Wed, 19 Nov 2003:
The person suggesting this solution stated that the heating coils (I
think they are actually electric tea kettles, IIRC) were each about 4
ohms.

Are these for use on vehicles, from 12 V, then? I didn't see that
article.

You can buy high-power resistors from Farnell/Newark and they are not
costly. They are even in the horrible UK Digikey catalogue, as 'Aluminum
Housed Chassis Mount Resistors. Eight 1 ohm TMC-50 type in series give
you 8 ohms at 400 W if you bolt them to a big sheet of 1/8 inch
'aluminum'.

You could build a dummy load in a paint can (available at hardware stores)
filled with mineral oil to dramatically increase the power handling of the
resistors. The kettle elements sound like a good idea to me though.
