Due to spending most of the winter months in Spain I always Sorn the Plus 8 and in the five previous years have had no problem with the car starting first time..
However today with it due for an MOT of course it wouldn't cooperate, the start button would light up but the engine refused to fire.
Tried the usual things, battery boost etc but no good, I then realised the 20A start fuse had blown as did its replacement.
Rang the factory for advice and as always incredibly helpful, they thought it was probably a sticking starter solonoid, a common problem with low usage and suggested changing the fuse to a 30A might solve the problem, hey presto, started first time with the new fuse.
Apparently the wiring can easily cope with running the 30A fuse.

I remember generic advice that starter solenoids can draw around 30 amps and so not to underestimate cabling to the trigger contact of same, say 10mm2. Very sound fusing advice given

That's useful to know - thanks for posting that....

Would there be any risk to installing a 30A fuse permanently?

Just spoken to one of the service engineers at Morgan and he said they had noticed the problem and later cars had been fitted with a 30A fuse.
So no problem to leave the 30A in and he didn't think there was any need to remove or service the starter motor.
I would say how lucky we are as owners on the odd occasions I have needed advice the factory have always been incredibly helpful, I doubt that could be said of other manufactures.

Hi, I've just experienced the same issue with my 2007 Aero and that fact it wouldn't start on Monday morning this week whilst staying at a hotel in Sussex. I blew 4no 20A fuses in succession and a friend said that 20A seemed a bit small for the starter circuit and to try a 30A fuse. This worked perfectly and that car has been on the button ever since. I called Jamie at Brands Hatch Morgans and he said there was a printing error with the fuse box diagram with shows the fuse to be a 20A when it should be a 30A and therefore leave the 30A in at all times. Simple and much cheaper than a new starter motor which is what I was anticipating!

It's been good as gold since the 30A fuse has gone in so hopefully as though the cure is permanent - happy days!
