T500 kill switch?

AFRetired · Post by **AFRetired** » Sat Oct 29, 2011 2:48 pm

In the middle of working out ideas for my T500 semi-restoration. I would really like to add a kill switch (other than the key switch) and have acquired a right hand kill switch from a GT500. But the GT apparantly operates by grounding the CDI, and I was wondering if anyone has any ideas how to wire this swich to kill a points system like my T500?

Hi AF.....check out the wiring for a later T500. They also had the kill switch.

I may be wrong but "I dont think so Tim."my 74 never had one.

Hi Alan....I've got 2 T500M's, both have kill switches. Tim's T500M has one too. In fact, I would go as far as to say, it's rare over here to come accross a 500 that doesn't have one ! Over the last 35 years I have owned a lot of T500's and until we recently built a cafe racer for a customer, which is a 71 bike, I hadn't seen a T500 without the kill button.....Is it possible the spec was slightly different for the Us market?

They didn't have them over this side of the lake.

Maybe it was a UK requirement then? I've never come accross this issue before, just assumed they all had them.

I actually used mine once.....back in 1977, I was showing off a bit, and decided to pass the Suzuki AP50 buzzing along infront of me, and the 2 cars infront of him. So I gave the 500 the berries and roared past, only for the ford cortina at the front to swing accross the road in order to park on the other side. The result was messy....I was dragged along the road about 30 yards after a 50 mph impact, to end up half under the bike. The throttle was jammed hard open on the road, and the rear wheel was turning flat out inches from my face. With one leg twisted under the bike, all I could do was hit the kill......so they do have their uses !

In the US it looks like they added the kill switch to the 75 T500.

I have the 74 & 75 T500 owners manuals. Wiring diagram for 75 shows a kill switch but the diagram for 74 doesn't.

As far as I am aware the the T500M of 1975 was the only year that a T500 has the kill switch mounted on the handle bar.

The 1975 M model was a cross over model between the T & GT500
& shared some of the new features of the GT :-

1)Kill switch
2)Oil tank outlet without trap
3)Crankcase breather
4)Swingarm mounted passenger footpegs.

The Wiring Loom was also unique to the M model with a different part number, this had the extra orange/White coil power wires so that the kill switch could be plugged inline to kill the power to the coils.

The parts book I have has this for all Markets so I asume all T500M's had Kill switches

Well I have certainly learned something !! Perhaps I just forgot whether the bikes I've had were fitted with the kill or not?

Here's another thing tho.....I have 2 75 T500M's. One will start and run, tho not well, without a battery fitted. The other.....dead as a door nail, not a glimmer. What's going on there ?
