Fitting heated grips - which ignition live to use?

[inchy1981]

As the titles suggests, which wire do you recommend I use, to wire heated grips to?

I dont want to wire it to a permanent live, as it will kill the battery, because I will forget to turn them off!

Could I just spur off from the tail light wire? Therefore the heated grips would only have power whenever I have my lights on (which is always).

Cheers

[J.M.]

Absolutely.

In fact, I re-fitted my heated grips today and did exactly that.

Probably best to find a slightly beefier wire.

Why not the ignition wires

But no. mine are wired into a relay to the front lights.

Definitely use a relay and an inline fuse.

The relay coil spurs off whatever you like, headlight, taillight, dashlight pretty much anything that comes on with ignition. The switched wire on the relay comes via a new direct feed from the battery, through the fuse, relay, heated grips and then to ground.

Much safer and you can use whatever switched supply you like then

Don't use the ignition wires as these sort of wires should not be tamperfered with. You can introduce unreliabiltyness into an otherwise sound system.

Feed the grips via a Relay. The relay should take main power direct from the main breaker or from a fused supple off the battery. Energise (Switch on or off) the relay using a signal from an 'ignition live' source. Head lamp or tail lamp circuits as suggested. Tail lamp can normally be got at easier than the head lamp wires.
Use a spiral wrap to protect your wiring where there is none. Chaffing can cut through other wires and not just your grip wires.

Do these oxford grips advertised described below work as well?
I'm wanting hg too, but not sure how to fit to my fazer

I just fitted my R&G ones yesterday straight to the battery. It shines a bright red LED infront of me when they are on so i cant see myself forgetting to turn them off.

Its also handy for when im due to go out on the bike, i turn the heated grips on then 10 minutes later start the bike up and the grips are nice and toasty.

P.S I have a Motobatt installed, hence why i can do this

Not sure what kind of person would inspect my bike enough to see the heated grips switch, and turn them on.
I have a 12v socket connected straight to battery too which hasnt drained any power, i dont think the grips use any power at all if they arent turned on.

I'll go by the 1 strike policy, if i forget to turn them off even once, and come back to a flat batt, ill wire them up with a relay, until that happens ill chance it with the battery connection.
I have breakdown cover anyway, and a motobatt, im pretty sure a motobatt could run heated grips for a very long time before running out of juice.

Hi

Another vote for using a fuse and a relay. I tend to use the feed wire for the rar brake light switch to trigger the relay.

[J.M.]

[EazyDuz]

How big are the relays? I ride a cruiser so theres barely anything in terms of fairings to hide electricals behind, infact most of the electricals are right next to the sub fuel tank, genius design.
I hate the idea of tapping into existing wiring as well.

If i find the grips are draining my batt or if i leave them on just once then ill wire it to a relay

Hi

Likely space behind a side panel to hide a relay.

If you use the rear brake light switch, then a replacement switch likely comes with a short bit of wiring to plug into the loom. Hence if you tap into that and make a real mess of it you can just replace the cheap rear brake light switch.

Leave the grips on over night and you probably will flatten the battery enough that it will be damaged.

All the best

I just fitted R&G grips too and like EazyDuz wired them straight to the battery. If I ever get a problem I will find a connection via the ignition. The led's glow nicely to tell me they are on, I will disconnect in the warmer seasons. I rarely leave my bike longer than a few minutes and it is parked next to my other bike in the garage with jump leads nearby. Everyone says you must go with an ignition feed - maybe but I'm ok at the moment.
