T180 issues

ok last night i setup my esc to the servo to get the steering right and every think worked fine, then later on i hooked my new 4s battery and had a few sparks from trying to hook it up- now it wont harm with the rx. i check over and over for anything i was missing, then hooked the rx to a mamba esc and it worked then i noticed what looked like the red lead of the rx connector was pushing out and managed to get it to hold still nothing. so i cut back the esc wires thinking there was some damage and checked all with a meter. did the multiple sparking when connecting damage the esc?

Do you have an external rx battery pack you can try it with?

[steveo]

nah , you think the bec is dead?

[siberianhusky]

Who knows, could be a few things but that one is pretty easy to test, next thing I'd check would be the caps.
Then try returning it.

[steveo]

thanks i'll try it

[steveo]

isnt there a wire i have to remove before doing this, if so which one

[siberianhusky]

Yep the positive wire from the esc to the rx

[steveo]

thanks again

You can check to see if the caps are bad since you have a multi meter. Without any voltage connected do an resistance check. Accross the pos and neg leads you should get at least a couple meg, probably more. reading. Connect up the batteries, that will charge the caps and measure again. You should see a very low reading, like a couple ohms at most. If you have 4S voltage applied to the caps and you still see a resistance in the mega ohm range you got bad caps.

yes it was a bad bec i wont bore you with the details is was a pain- now to get an rx pack one of the boats will be using 5s anyway maybe this was a good thing
