urgent help needed

[Alex Joyce]

not specificly a mardave problem but -

just crashed at 30mph into a wall

this happens all the time but i only break wishbones

now my v12 dosnt work

i have an esc and hitec radio gear

esc light dosnt come on like it should

servo dosnt turn

if i switch the car on and off (esc switch) the servo twitches

can any one tell me whats wrong

[si mac]

not an expert but i would suspect the receiver first of all. check all your connections, plugs and solder joints and try again.

Sounds like you're having a problem with power getting to the receiver. Check all the servo/esc plugs, and make sure the crystals aren't knackered (you can tell whether its broken if the crystal has a wobbly leg, or if there is faint rattling if you shake it. Alternatively, try some different crystals if you have them). Check your battery plugs to make sure they are making a connection. To see whether it is the receiver, try another one (if you have one. If not, borrow one for 30 seconds!). Other than that I don't know what else to suggest. :-

If the ESC doesn't light up, then there may be a problem there. Check all wiring, switches etc, and make sure that there are no loose connections. Also, change your crystal, that may have been damaged.

[Mark Stiles]

The esc not working could be down to a number of things;

Complete lack of power (check battery wires)
No signal from receiver, so not adjusting to neutral (check receiver wires, crystal etc...)
The worst scenario - the esc has blown (throw it in the bin or try and get it repaired, if thats possible!)

thanks for the help - ill have a look when i get home

might plug battries str8 into the rx to see if thats bust - eliminate each thing

[Doughty]

be VERY careful plugging your batts into the rec.

if I remember correctly you speedo steps down the volts so you rec only gets 6v not 7.2v from your batteries.

please check before you smoke something

did the connector from the esc come out! if so try the connection from the esc to the reciever the lighter colour wire should face towards the middle of the reciever this could be your problem :cool: my car had similar symtoms after this mistake
