hi all
this problem concerns block of wood some might remember it from wigan any way we cant get it to run at all. we have done some volt readings all normally the power is getting to the speedo and to the motors but no response
any ideas?
i will try changing the speedo see if that does anything, but for now it isnt working!
cheers alex
your getting a voltage to the motors?
If thats the case is the motor turning inside? If i remember rightly it was having problems with slipping clutches at wigan so maybe the balls for the clutch have come out or have no force pushing them into the clutch.
i dont think it is tyhe speedos, but the arent clicking or do anything, what i mean by getting voltage to the motors is there is power at the positive and negative wires coming out of the drill motor
yes it was slipping at wigan and to solve this my dad was told to lock the torque by putting a screw through the black housing with torque numbers on i know this isnt the right name but any way
if it was what you suggested grant how do we solve it?

well even if the speedos arent working theyre is still a problem with the motor/gearbox if there is deffinatly power going through it. Its possible that the screw put through the black plastic is done up too tight.
Just to check it, see if you can turn the output shaft by hand easily. If not then thats your problem. The screw will be pushing into a steel ring inside, this ring has lots of knotches in it and the screw wants to be screwed into one of them. Tighten up the screw untill there is a slight amount of play in the output shaft before it starts to turn the motor, atleast then you know it isnt too tight.
Grants solution is probably right... but Id expect some clicking and humming if you have jammed the gearboxes and effectively stalled the motors.
try running leads direct from the battery to the motor terminals to see if it moves...
When you say you are getting voltage to the motors, have you measured it? try sticking a small lightbulb across the terminals where the motor would normally be, it should get brighter as you apply power.. or use a volt meter if you have one.
have you checked the reciever battery?
connect up a servo to a spare channel and see if it moves?
also worth checking simple things like you have the same crystal in the Rx` and Tx... and that the Rx crystal hasnt fallen out...
Are the main batteries both charged fully.. if you have a duff cell in one pack it can stop everything when you put a load on, but it may register a full charge on a voltmeter.(its happened to me and drove me round the bend trying to find out what the problem was)
equally if the main batteries arent fully charged , some speedos wont have enough ooomph to open the relays (though i think electronize operate down to 6v)
ok it isnt the motors not turning, the funny thing is i have done some volt readings accross the battery 12v postive from bat to negative on one of the motos 12v then neg from bat to pos on motor and its 0.5volts would this have something to do with it?
we would like to get it running for the weekend so if anyone has any idea whats up because i dont have a clue!
cheers alex
replying to robs post, checked the reciever battery and the we are using SLA battery
Youll need to have your transmitter and reciever on .....then readings should be taken across both the terminals of one motor....whilst wiggling your transmitter stick.
A voltage reading of the SLA battery would also be helpfull.
Have you actually tried... as suggested..... disconnecting the speedos and simply testing that the motors spin by connecting the battery directly to them?......Id try this first.

ill try the suggested idea and post later
cheers alex
yes the motors do run when the power is put directly on them
also early i swopped the speedo for one of mine, the motor did turn full power with out me doing it but when i did move it nothing just like before!
