No Power to Motor!
Ok so yesterday I decided that for one of my gen1 cars I would fit a pro-board harness / dean's plug properly, e.g. right to the board rather than just soldering it onto the existing wiring, and whilst I was at it upgrade the stock motor wire.
I used 18 gauge wire so had to drill the holes a little but when I put everything back together all was fine and the car ran great. So today I decided I would exactly the same mods to another gen1 car. I fitted the pro-board harness / dean's plug and tested that the car still ran, both the servo and motor functioned, so I continued on with upgrading the motor wire, I drilled the holes and fitted the thicker wire, applied solder and all looked fine! So I hooked up my motor and liths, the servo turned correctly but the motor only spun very slowly a few times and then stopped - I wondered if I had blown the motor so I slapped another on with the same results! What could I have done? I have checked for bridges or shorts and everything seems fine! As I said the servo moves its just my motor that is screwed! Maybe I drilled to much and removed the contact points on the board - so could I just scratch away at the surface to get to the metal plate (like when you do a power-switch bypass) or is that going to screw things up?? Any ideas are much appreciated! |
can you take a close up picture of the places you drilled into?

Hopefully you can make these out: Top of board: http://www.ab1gworld.com/images/board1.JPG This was the side I drilled into. Bottom of board: http://www.ab1gworld.com/images/board2.JPG Little blurry but you should see two holes in the top corner. [EDIT] Oh well looks the board is completely gone now! No servo movement or anything! This is just another expensive lesson learned about xmods! Don't drill holes that are to big! |
hmm, could the holes be too wide and are touching each other?

i wasnt even upgrading mine, just replacing some wires that came off, and the servo works great and it wont move a cm:****ed:

Check that the cells are fully charged. Pull the motor end bell off and see if the brushes are worn, And double check that your solder connection isn't bridged. I would imagine that something would fry, but I've seen stranger things. My suggestion would solder a leg(a solid piece like a lead off of an LED or resistor) to the end of the wire that goes into the EP so you don't have to drill the board.
