Deauville Alternator Capability?
 

Hi All:clap:

I have a 2004 NT650V Deauville and have heated grips installed which draw 16watts each on full power. Also I have a Garmin Zumo 550 which I guess might draw about 5watts? Now I am thinking of using a heated jacket liner which draws 77watts on full power and so I will be asking the Deauville alternator to put out 114watts or 9.5 Amps additional to what the bike needs to power its own systems (headlamp on permanently) and to have a few amps left over to keep the battery topped up.

And so I am wondering if anybody can tell me what the alternator max output is and as to how near I am coming to that magical figure.

Thanks kindly in advance,

Hi Declan,

A 650 Transalp makes 368 Watts. Since the Deauville has the same engine, more or less, and presumably the same alternator-but don't quote me- I reckon it's fair to assume it puts out the same power.

But I could be wrong.

Thanks Crusty,

I think those are fair assumptions. I wonder how one would measure what full load is, I suppose you'd need at least something to soak off 400watts, but what next?

Ideally, you'd fit an ammeter (capable of measuring up to 40A in either direction) in between the battery and everything bar the starter (i.e. between the battery and the fusebox). Then you could see whether the net flow of charge was into the battery (alternator supplying more than everything is drawing) or out of the battery (alternator not keeping up with demand) and you could see it real time as you switched stuff on and off, and revved the engine up and so on.

As an easier alternative, you could fit a voltmeter across the battery instead, but then you'd have to wait for any over-consumption to cause the battery voltage to drop before seeing whether the alternator was keeping up.

HTH,

Thanks Dan,

That seems like the definitive way of doing it and as soon as my vest arrives I'll try your suggestion. Thanks
