Electrical problem

[Wangler]

Thanks John. I’m not sure it’s as bad as the standard setup!

The blowing of fuse 9 stopped my engine when I was underway, fortunately on a quiet country road near home. I think that bypassing the fuse, which also supplies power to some relatively non essential items, is a good thing to do and indeed that’s what I’ve done by taking a live feed off the input to fuse 9.  But not then putting in a fuse inline seems strange. It’s unlikely to ever blow unless the coil malfunctions and shorts out inside, in which case the engine will stop anyway, so an unfused positive wire seems an unnecessary risk. Maybe I’ve misunderstood your suggestion?

Isn't protection of the wiring supplying a component, the purpose of a fuse? This month this happened 100 yards from me.

Richard, as I said, it`s your car, you do what you feel comfortable with. As you say, if you only supply the coil then put an inline fuse in if it makes you feel happier. As Sean commented earlier, the main feed from the Starter motor that supplies the whole Fusebox and the ignition switch is unfused.
Richard I think that`s a boat fire and anything could`ve caused it, not necessarily an unfused wire.

[Richard Fridd]

Yes, a boat fire.  An electrical problem seems to be a possibility. I understand the boat was unattended and the battery isolator could have been left on. Our mooring master reports 25 moorings now out of commission until localised pontoon damage is repaired. Insurance claim in progress I think.
