Went shopping and bought...

[P_J]

I originally went in to buy some heated grips after the stupidly cold morning we had the other day.

I saw that Hein Gericke do a 'store card'. Great I thought new stuff and I don't have to pay for it just yet . Turned out you had to spend over £75. Not as easy as it sounds when you only want 1 thing, and that thing is £49.99.

The heated grips I bought took forever to fit because I was fecking about in the dark last night at about 6pm. It was well worth the hasstle though this morning. Toasty warm hands, and no frost bite Highly recommended

I bought the wrap around the original grip ones. My hands felt a but stiff when I got home tonight though, anyone else have this problem?

I also bought some 35/35w bulbs. They are better on paper than the 25/25w ones I removed but they don't seem that much brighter in reality. It has been mentioned on here before that 45/45w ones are to hot? Is this true because I am tempted to go and buy some brighter ones.

To make up the £75 I found myself ordering a quick release connector thingy watsit for the fuel line. Anyone had any experience with these?

Do the oxford hot hands come with a switch?

i'm thinking of getting some but also don't want to have them on when i'm not at the bike or something. I think i'll wire them into the ignition somehow

Any ideas?

Hi

I am probably going to run a wire directly from the battery to a relay, and then feed the switch for the heated grips from the relay. I will then try and break into the wiring somewhere to provide a trigger for the relay when the ignition is turned on.

All the best

kickstart, why have a relay? just splice the grips directly into the power lead connecting to the ignition

You could in theory splice it into any of the electrics wiring as they should all be the same current ?? As there are no resistors in the wiring circuit from ignition switch through inidicators/lights etc

so, you should be able to connect the heated grips lead into one of the indicators wiring, then wire both of them (use a connector box!) and power them both!??!

Would that work as well as I think it will? Or not?

Hi

Not sure how much current the grips would pull, but it could easily exceed the rating of the wiring you are tapping into.

My old FZ750 had a 100/80 headlight bulb in for quite a while. The extra power of that (standard was a 60/55, so on high beam an extra 40w, which at 12V is just under 3.5 amps) melted the wiring the the ignition switch. This is not an uncommon problem with the FZ750, and probably shared with any other Yamaha with the same design of ignition switch.

I would not be surprised if the heated grips pull 5~10 amps, especially in the high power warm up mode. Doubt much of the wiring would take that much extra current passing through it.

All the best

Hi

Ah, 3 amp fuse. So that means they are pulling about 30w at a guess, more than one of the standard headlight bulbs on the NSR.

The other problem with a switch is kids playing with it. Not unknown for people to come back to their bike and find the suspension played with, and I would expect a switch that illuminates an LED to be even more attractive to kids.

All the best

What kind of Wattage can a bike battery give out (or have taken from it) before it gets tired?

bollocks I'm going to wire the grips to a seperate battery under the seat and re-charge the battery when needed.

Can't be arsed with draining my bikes battery when I forget to turn the switch off (which I will)...

I work for an electrical contractors so can get all the stuff for cheap (cough) free

Hi

Depends on the bike. From memory the NSR alternator produces ~ 120 watts once at reasonable revs (but I may well be wrong there). 50w will go on the headlights (or 70w if you stick 35w bulbs in there), another 5 for the tail light (or 21 for the brake light), say another 10 for clock lights and side lights, plus indicators, power valve, coil and the like. With the 35w bulbs in the front the charging system could well get marginal (add that lot up along with the heated grips and you are running at over 110w probably).

It is possible that you had enough of a drain on the charging system that it was beginnning to struggle to provide sufficient power for the coil to generate a good spark or having problems powering the power valve motor, especially if you were running round town with the revs fairly low.

Think the NSR uses a 5aH battery (ie, basically 60w for an hour).

All the best

fit two batteries

I'm struggling to think of a place I could wedge another battery into my NSR

Might be able to fit a nice little 9V one in there somewhere.

Or you could probably get a more powerful (higher AH rating) battery of the same size. Won't stop you overloading the charging system, but will help if you do.

[Milo]

not that i've got an alarm...but if you could work out where to put your two wires you could connect it to that.
that charges it's own battery off of the bike's but doesn't let the bike's battery dip below a certain amount - just what's needed for this situation.
Is anyone good enough with electronics that could make a stand-alone circuit like that?

Hi

Another option, although a bit crude, would be to wire it through a 2nd relay triggered to turn the current off when the brake light is illuminated. This way when you are sitting with the brakes on the heated grips would be turned off. Should minimise the current drain when the engine revs are low and the electrical system barely charging.

All the best

I wouldn't wire em into the ignition as if something goes wrong it could leave you rather stuck. I wired my Daytona grips into the headlights, my lights are 55w and so are the grips on warm up mode, but 15w on 'on' mode which is also quite useless. With the headlights u dont have to remember to turn them off as there is no power going through there when the ignition is off or your headlights are off.

[Kickstart]

Hi

Think you could fit a bigger battery, except there is barely room for the standard one on the NSR. You could run a 2nd battery in parallel and the charging system would probably manage this. However in both cases you are just delaying the inevitable.

Suspect if you used a 2nd 5aH standard battery it would only manage to power the heated grips for a couple of hours. Also it would likely have a short life if you ran the battery too low.

All the best

with a second battery wired in to the altenator it would keep charging the extra battery (if it needed it or not) if the primary battery needed it. so if it gets full and the primary is charging then it'll bubble over.

wiring it into the headlights would cause similar problem to the wiring - it could easily melt it.
2nd seperate battery sounds like the best plan but then there's the hassle of charging it. i park on the road so it wouldn't be an option for me, unless you had a bumbag with a few batterys in that you could easily charge
hmm, radio controlled car battery's produce 14Vish from memory and quick charge in 30 mins. a couple of them on you for the way there and for the way home would probably do the job - though i don't know how long they'd last on the higher-power warm up mode.
maybe a few of these gaffa taped together and wired in series (or is it paralell?) to give the same voltage but would make them last longer. sounds easy to me.
just have a optimate type connector on both and it'd be a cinch.

anyone got some to tell us the voltage and amp/hour rating?
