I have the same engine, and was wondering about spare fuses, thanks for the very useful information! I am not sure though, if the 25A model is used, the wire is thinner than this one:philipstevens wrote: ↑Tue Jan 03, 2017 9:46 am The fuses could be 40V 25A. If so, they are old automotive Bosch Type GBC fuses. The highest rating I could find was 25A.

If you want to replace the fuse holder, all I can find is a four-way block. http://www.12voltplanet.co.uk/continent ... 4-way.html
As you say, difficult to get hold of as they are rarely used - only on older cars etc.
The fuses are there to protect the smaller size wire.
Carry on as you are going, using the one good heater to start with.
