[C320-list] Alternator Fuse on Yanmar 3YM30 powered 320 MK II

[Ian Neale]

Thanks everyone for your comments. 

The issue turned out to be the earth cable on the block of the engine coming out of the crimped lug. Initially it must have been high resistance and then as I got to the berth the engine meter panel died and I could shut the engine down without using the manual shut off. 

The biggest issue was the problems meant we missed the last race of the Americas Cup 😩. We did see the others from the water which was great. 

Now today I have had tach issues as described in another chain of emails although it is intermittent. It does seem if the alternator is still charging. I will see how performs over the next day while at sea and report back to let you n in is what I find. 

Thanks, Ian.
