Strubbly

Woo-eeee!! One of the motors came to life after being dropped 1m onto a tiled floor. I think the "impulse" that worked was up the drive shaft - presumably it jarred the metal plate back into position. But the motor bounced more that once so that might be wrong. I can't get the other two to work, but at least I can get started on my model... Thanks for the advice.

Wow! Quick responses: thanks! I don't have any other 9V motors - I've never used them before. I also don't have a voltmeter but I've tested all the batteries in another device which shows low battery and they all show as full power. I've cleaned up all the terminals, though they looked pretty clean anyway - no luck. It's weird the way all three motors make the clicking noise but don't turn. But it doesn't really get me anywhere. I think I'm going to have to go back to the sellers...

I'm trying to put together a motorised model - a bit of a departure for me... So I bought a mini-motor from bricklink, and then a couple of 8735 sets from eBay. So I have 3 71427 9V mini motors and 2 battery boxes and connectors and stuff. It all came today and so I excitedly connected the motors and ... zilch. All 3 motors make a tiny click when I switch on the power but nothing goes round I guess maybe they're broken - but all 3? Am I doing something wrong? All 6 AA batteries are new - and even if one was a dud I'd still expect the motor to run. Is there a common problem with these motors or am I just unlucky? Any suggestions on a better way to test? Should I be asking for my money back? Ben
