Hi there, I'm trying to repair a motorised toy, it runs off 6 volts of batteries and spins a fan. At the moment it begins spinning and then stops within 2 seconds. The rest of the circuit is just switches and they've checked out ok. Attached to the positive side of the motor is a square yellow componen, shiny finish, about 4mm square. I've noticed that this heated up quite considerably. Printing on it has 2 V's interlocked, one the right way up, the other upside down, follwed by 30 and then UF090. On the back is EIHA China (manafacturer perhaps). The other component, circular orange slightly bulbous disc, is connected between the two motor terminals and has just 104 printed on it. Can anyone a, explain what these do and b, is it likely to be one of these components that is causing the problem. I haven't checked the motor yet because I think that would mean desoldering it all to avoid the bridging component. In hope of learning and fixing, Julian
