Another ETEC breakdown !!

Starting to dislike my etec... Battery voltage now showing 12.16, battery low voltage alarm sounding, changed to spare battery, same issues... To the lay man that's the alternator goosed !? Sound about right ?

I take it youve cleaned up any in line connections to isolators if you have any, and cleaned the connections onto the engine etc ?

Has this boat been living in damp conditions out of season?

12.16 volts should be plenty to turn over? Start it by hand and then read the alternator voltage, think it should be 55 volts

Check what voltage you have on your instruments and compare them, could be that the meter you're reading the voltage on and the alarm sounding is out of calibration.

'Coz leaving lots of fairly trick leccy bits in a damp cold atmosphere for a few months can lead to niggles.
I'm super fussy, mine (sister to your's) lives in a sealed, draught free shed all winter, with an industrial dehume running on timer.

We'll see next week whether she comes out of hibernation trouble free or not.

Did you do the winterisation process before storage ? I would have thought that would have been adequate for leaving outside as well as in.

Winterisation only protects the motors internal guts. It does nothing for the electronics under the hood or every other electrical item on the boat.

Condensation is the nuisance.

Does spraying that quicksilver grease stuff on help to eliminate that.

No, but a good DWF spray helps. I use this one...

Big difference in price Mollers I paid 20 odd quid for that quicksilver stuff. Can that be used over the top of it or will it just make a mess of the grease already on.

The Quicksilver Gunk is great for preventing corrosion on the block / bolts etc.

For electrics the main thing is to use dialectric grease on connectors etc every couple of years to prevent corrosion. THe ECU itself is total sealed so that should be protected.

Where exactly are you spraying this stuff? Corrosion guard is designed to prevent surface corrosion, not to be blasted around liberally under the cover. It may even trap moisture in.

When I'm winterising our engines, I remove the hood and side cowls on the Etec and spray hose the lot to remove any salty deposits, leave to thoroughly dry, then apply a nice coat of 2040 to the lot. The hood/cowls then stay off all winter.

Mine used to register at about 13.8v on the LMF400 gauge when underway. I would remove, clean and re connect all the main power cable connections. If you still have a problem try by-passing your isolator completely.

If you still have a consistent low voltage this can be caused by the alternator or possibly the EMM (hopefully its still under WTY is the EMM is the cuplrit !)

I'm afraid I have done the first paragraph thats what the guy who sold it me told me to do.
