headed jacket wiring advice please

[degsey]

I have just took delivery of a new heated jacket I have a couple of technical questions I need help with

What is the rating of the accessory socket on the GS?

The jacket has a 15 amp in line fuse can I remove this if yes has the circuit got adequate protection

Lastly is the centre terminal of the accessory plug positive

Cheers in advance

5 amp draw is the standard under the seat / on the beak aux socket limit.

Yes, if you are just plugging it into the standard (unmodified) aux socket under the seat you could remove the in-line fuse, though there would be no advantage in doing so.

If the heated clothing has an in-line fuse of 15 amps (and assuming it's the oroginal fuse, not one some bod has lobbed in) it suggests that the clothing will draw well over 5 amps, so it will trip the bike's protection circuits.... so direct to the battery (via a suitable in-line fuse) you will have to go.... or fit a relay.... See 'Switched power the easy way' sticky.

spot on thanks, just spoke to the local dealer who has said basically anything more than 4 amps wire it direct to the battery as the jacket is 85 watts which draws about 7 amps its the battery option for me

Splendid

A 10 Amp fuse should be fine then, even allowing for a bit of extra current draw when the jacket first heats up. Give it a whirl at 10 amps, if the fuse blows go up a notch....

Measure the resistance of the jacket.

Divide 14 by the resistance figure you just measured (where 14 is the voltage when the engine is running).

This will give you the current draw of the jacket.

Simplez.

Thanks but is not the rule of thumb watts divided by voltage adequate, or I guess your calculation will give me an exact draw.

Just do as Wapping says, up the fuse value if it blows

I've wired it to the battery, as the dealer reckons 4 amps max, any more and the canbus system shuts the socket down resulting in having to switch the ignition off and on again

Yes you are right; I missed the earlier post that stated the wattage.

Its not a Gerbing jacket is it? That draws ~6A @ 14V (=84W).

Keis jacket, according to the instructions it uses 85 watts

I've got Keis kit - and it's wired direct to the battery.

You can work out the current draw from the wattage at 12V. It should be just over 7 amps.
