I have been given Oxford Touring grips to fit on my 2015 Bonneville T100. I don't want to connect direct to battery in case I forget to turn them off and flatten the battery. Can anyone advise how I can wire into a switched circuit?
You might be better doing a new install complete with a relay and fuse operated by a low-amp switched circuit so you dont drag too much juice through existing cabling. Just remember that even with a switched circuit operation if you leave the heated grips on, then as soon as you turn the ignition on they will draw current and could compromise your engine starting?
If they are the 'premier' version (or whatever they call them) which are what I put on my SIII, they have a low battery mode and are supposed to cut out themselves.......Luckily I've not had to test this theory yet! I find even at 50% they get pretty damned warm pretty darn quickly and that greatly helps in aiding the memory to turn them off. I've found it just kind of becomes part of the dismounting the bike routine.
Go for the relay route much safer. As close to batt as you can. This way you are drawing less power, and when the ignition is switched off, so are your grips or other accessories you use in this way. I personally use 16guage wire. As thebiglad states your grips will be dead until you switch your ignition back on if you do not have a indication light on the control switch, you could fit a led to show you when they are on, to save your battery when trying to start in the cold weather. 87 plus fuse + batt 86 - batt 30 to your live on heated grips 85 to a switched live ie: rear lights, brake lights.
wow there are some clever people in here,lol I know some people take a feed from the lighting or horn circuit,dont know if that is good or bad as I had mine fitted for me,didnt fancy messing about
My Oxford grips were wired direct from the triumph dealer which I thought was odd. I think that it was because the bike runs on a CAN-bus electrical system and wired through the normal route it may not work and be rejected. On the plus side they turn themselves off when the engine is not running so no worries there.
Mine are straight to the battery (as per the instructions - too much effort to think about changing it) and work fine. The most difficult part was getting all of the excess wire length hidden away due to the battery being right at the front of the bike! At some point I may chop them down and tidy it up a little, but for now, it's winter(ish) and I just appreciate the fact they work! :0)
