Hello all, I wish to add a relay for wiring in accessories,the plan is: wire from ignition to activate the relay, wire direct from battery via the relay to a small fuse box that will be fixed in the tool box, accessories powered from the fuse box, this way I can add my heated grips, 12v socket, and anything else i wish (im thinking some LED spot lights for the dark winter months), this will also help to tidy up the wiring a bit. The bit im not sure about is what type of relay I need, I assume there are different types, any help here would be appreciated. Thanks

4 terminal normally open 35a relay from a car shop eg: maplins http://www.maplin.co.uk/40a-spno-and-30 ... elay-37526 , second one shown , HOWEVER you will still have long wires running to your items , think of a way to move things forward

hope this helps , most relays have std pin numbers http://www.mp3car.com/imagehosting/1252 ... 233622.bmp

Cheers Alan, the length of the wires are unavoidable at least for the heated grips as they also act as a resistor, the excess is currently hidden under the seat, as for the 12v socket that will be mounted in the tool box so there wont be hardly any wire.

Hi BERTIE ------------ what's the output of your alternator ??? Will it power all these extras or will you need to fit an uprated stator ??

AlanR , do you remember my posting a few weeks back , asking for help converting an old Suzuki trials bike from AC headlight to DC , and all the questions involving coils?, the bike is running (6v) with a h/light and indicators etc with a tiny 4ah battery. providing the lights are not left on 24/7 its a good un.

the tech side: those little suzis have a ac regulator that holds the 30 odd voltage to 6-7 volt , I removed the earth from the coil and ran a new wire , the two wires were then fed thru a 6v reg/rect and to the battery the charge coil gives out about 30w @ 6v , (this is about 15w @ 12v) the system works well!

regarding the heated grips , can be run easily if the bike has a good battery and a NORMAL charging system.

From memory Bertie has a 4 wire stator and if converted to a D/C only then there is a bucket load of power available from the alternator

a relay will fit between the gusset between the top and down tube thus reducing the load before the heated grips

Hi guys---------- sorry, have I missed something here ?? I was under the belief that, no matter which way you approach it, it's the total WATTAGE consumption of a circuit (not the volts) that the generator has to power ??

Bertie, if you are going to use Oxford Hotgrips they have a black box that goes into the tool box and this is where you fit the relay. Power through a fuse to the relay and out of the relay into the black box. Ignition on trigger wire you can pick up from the power to the rear brake switch and the remaining terminal goes to earth, into which I fit an isolation switch so that during our long summer I can isolate the hotgrips completely
