Hi Mike
I like the idea of a micro switch on the throttle pedal. My switches are all on the gear lever but it was tricky to set up.
I favour the switch being above the pedal, so that as soon as its moved from rest the unit is powered up, it should avoid having to maintain the switch operated, over the whole pedal movement.

I have my motor mounted in slots for chain adjustment but found that it slid in the slots, and I needed a threaded adjuster onto a backstop, a bit like a bicycle wheel adjuster, but it pushes rather than pulls.

Best wishes
Walter

Hi again
By the way, I fitted my sprockets onto the shaft by drilling and tapping the sprocket hub, and putting in a bolt that locates into the keyway on the shaft.

Don't some controllers go into fault if the speed pot isn't 'central' when the controller is started? It stops turning on the controller with the speed controll at full (maybe without even knowing it) and launching yourself into next week..

Hi Tufty
Yes thats true.
If I try to change from forward to reverse without letting the throttle pedal right up, the controller goes to sleep!
I have to arrange that the pedal is UP and the power off at the time of changing the direction switch. A microswitch on the pedal would have saved me quite a lot of setting up, on the switches on my "gear lever". Getting the sequence right was quite a fiddly job.

Evening Walter.

What I meant by that was pushing the pedal down to release the microswitch would also move the pot, by the time the controller 'starts up' the pot would have moved even further probally to a position where it would fault the controller.
Unless you were very carefull with the right foot.  I know for a fact that mine doesn't even know the word carefully when it comes to throttle control.  

Although from what I remember from your setup you could prehaps make the chain to the wig-wag a bit looser so the pedal moved quite a bit before the pot moves?

Thanks Walter, yes I think you are right as the wires for the micro switch are slightly thinner than the ones for the brake. I think it may have a fault as when I tested the scooter, I had put the lever in freewheel mode (which is supposed to disconnect the motor electrically) but the scooter still went! The brake also worked when I released the speed pot (and locked the back wheels every time from speed). I therefore agree that this is really a parking brake. I wish I had tested it a bit more now to see what happened when the lever was not in freewheel mode (I suspect no difference due to the fault). Having thought about it, I think I will not require the brake as it is going to stretch the chains every time the vehicle stops (if it locks the wheels on tarmac) or make a right mess of my friend's lawn! Hence it may be easier to revert to plan A and use the 4QD controller because if I try to fool the scooter controller, it may not work. Unless I unbolt the brake and leave it hanging loose so it thinks it is working. Mike

Hi Tufty
Yes, I think you're right.
I hadn't thought of that. As I have it set now, I have to put the lever in gear (which also switches the controller on) and then operate the throttle, If I'm a bit enthusiastic on the throttle it is possible to confuse the unit and it goes to sleep.
If the "ON" switch was fitted on the pedal, I think the throttle would beat the controller start up every time.
So it would probably be even more of a problem to set up.
Take care

Hi All, Richard gave me a good tip last night - why not mount the wig wag under two parallel pedals, one for forward, one for reverse? I know it's not like a real car but it is only a kid's vehicle after all. I'm trying to imagine in my mind how I could make a narrow reverse pedal, slightly higher than the forward pedal and mounted on the right hand side, up against the side of the body. The forward pedal, which would be used much more often, would be wider and slightly lower than reverse, so you would conciously have to lift your foot to press the reverse pedal.

Hi Mark / Brian,
Can you tell me where you obtained your remote kill swithces from? I looked at Technobots site but couldn't find anything. Only a $70 unit from USA.

To:Mike, I got mine off Ebay from China but I have found several similar ones in USA, I don't know if this link will work but I'll post and see.

Regards,

Brian.

Brian,
Thanks. I found it on ebay using the part number you provided. I think I have 12v relay in the shed from an electric car aerial. I was planning to insert it into the ignition switch (maybe this is 24v on the scooter - must check somehow). I notice from your wiring diagram you have put it into a throttle wire. Not sure why you have done this but it may be to do with your master switch being rated for a higher current.   
Regards
Mike

Hi Brian,
Remote cut out
I noticed that there are two types of remote - one that just acts as a switch and one that outputs 12vdc to a relay (which you have used).
Either will do the job, the RP100 or the RM100 plus a relay, in the ignition switch.
 
I've e mailed the company because I would like to know with the RP100, if you turn off the power to it, does the switch stay in its last known position or does it always open the switch? (If it always opens the switch, then I will need to press the green button on the keyfob every time as well to start the motor. This could be a nuisance looking for the keyfob as well, since it will only really be necessary when the car is being used in a public space).
 
If you turn off the power on the RM100, I guess the 12vdc output always falls to zero? In this case, I could wire in a normally closed relay (as you have done) so the car will run all the time without having to press the keyfob first time. When the green button is pressed, it will energise the relay and cut the power. Of course, if the child is smart, he'll realise he can turn the ignition off, the RM100 will de-power and away he goes! Is this what hapens with yours?
 
You'll realise that in both these scenarios, the remote controller is wired through the ignition switch as in your wiring diagram (otherwise it will drain the battery if permanently wired or need a seperate switch to power it up).

Took my scooter axle and sprockets to a machine shop today; hope to get them back Friday and maybe having it running at the weekend (will post some more pictures then). 40Ah batteries, indicators, knobbly tyres, just like the one at the back of the manual. on board battery charger (from scooter). Using the wig wag on the throttle box with two pedals now (one F one R). Some time ago, I bought the red throttle pot and a remote hand controller which won't be any use now but I just had an idea tonight - if I can get hold of a spare potentiometer from another Hurricane, I can replace the one in the hand controller and still use it!

Regards
Mike
