Quick Fix Needed
 

fitted symtec heated grips but I was not impressed with the performance. Actually I thought they were total rubbish so I decided to check all the wiring.

All seems OK except that I think the switch may be busted!

When I switch hi or low I have 12v from both terminals? The blue wire and the white wire. Does this mean the switch is no good?

One night to fix it as I will be away at the lakes.

Any ideas..............

Mr Dastardly, just get yourself to the Lakes dooooo and we'll have a look. I will be bringing my bike in the back of my Transit so we can swop the switch over to check............... and if you really need your grips heated you can have my switch and I can get another ............whenever!:incon_aargh[1]:

(PS I've got Symtec as well, they are not the hottest and can take some time to heat up.)

See ya there.:Gangsta2_9BI664:

Many thanks Steve.

See you in sleep or two

Not necessarily.

Hi Colin, afaik the red wire[very odd] is connected to the earth and the white or blue is connected to either side of the switch with the 12v feed in the centre, so your readings seem correct dependant on switch position.

as you have a multi meter test the voltage drop to earth, as unless it's connected to the frame it may get resistance perhaps through the bearings if the earth is connected to the handlebars etc.

they can be slow to heat but they do work well. initially i had them on the tenere [oxford hotgrips now, present] and now are fitted to my gasser. tho for some reason i have the white going to earth and the red and blue together recieving power via a switch. mucho heat.
I recall studying the circuit layout and coming to the conclusion as to gaining the most heat, it may invalidate the warranty of the grips but they are hanging in there and get proper warm. your call!

You will get 12V at each of the outer terminals on the switch (when the grips are connected up) as there is only one element in the pad, it�s just effectively divided into two because the (red) ground is tapped in the middle. When you have the switch in H (white), the whole element will be at +12V, but the current will only flow round one side as far as the point where the ground wire is tapped in and run to earth (high resistance hot side). With the switch in L (blue) the current will only run through the other part of the element (low cold resistance side) up to the ground tap.

Agree. The most likely reason for no heat is a bad earth connection, check that first, go back to �ve battery terminal if you can.

(You weren't tempted into testing them out before fitting them to the bars were you?? They burn out easily without a some sort of heat sink.)

It�s worth noting that the very latest Symtec pads have now got black as ground not red (more logical), although most places are still selling the older red ground kits from stock � a recipe for confusion in itself!

On the ones I had on the Ten I put 12V through the red ground wire (backwards) and wired blue and white to earth for maximum heat and used a waterproof two position switch instead of the one supplied. I did this as I had slow warm up/not enough heat (which I put down to the thick gel grips I had at the time). The Symtec's heat output seems to be very much linked to the variety of grips you use with them.
