Very interesting, as you say electrical is a different fame on a boat?

Hey Rob

Good to hear from you, dropped in at my marina sparky and he popped down to have a gander, told me the batteries ran to low, we had some mad storms in Sydney and we lost power on multiple occasions and after 3 years of work, he reckons that pushed them over edge. The sulphur smell was coming through this morning.

Not sure what you mean by DVMs, but we been out for 8 hours now and we holding well, currently drawing 7 amps, sitting on 12.9v

Cheers Pierre

Hey All

Okay problem solved, found I had a dead cell in one off the deep cycle batteries, this caused th ALT loading up and running hot, ran off this morning and bought 2 x 290 AGM batteries. Fitted them and we back to normal, ALT on the starboard engine now 65 degrees C.

So all revolved around the batteries.

Cheers P

Morning Rob and All

Thanks for the reply, did a few checks today, ran the batteries up 100%, checked voltage 12.5v, started starboard engine and kicked it up to 2000rpm, put everything on. Did a voltage reading and it came in at 14.7v, so it seems to charging the batteries okay.

But within a minute you could smell that burning smell and the alternator got up to 98 degrees C.

Took belt cover off and no slipping, belt in could condition. So not sure what is going on, port alternator is good.
