81F Posted November 3, 2016 Share Posted November 3, 2016 Just bought a Hornby Dock Shunter (Circa 1977 judging by the box - white line drawing on black inlay card) and I would like to give it a tst run before fitting a chip. I apprecate that prolonged expsure to the DCC will burn out the motor but I only test run for a few seconds so that will probably not be an issue. However, will the bulb blow as soon as the power is switched on? Link to comment Share on other sites More sharing options...
Fishmanoz Posted November 3, 2016 Share Posted November 3, 2016 Reframing your question a little - will a 12V DC bulb blow on 15V AC? Answer - most unlikely. More importantly, will a DC motor blow when subjected to a DCC signal for a short period? Probably not but one day yes it could. Get a cheap DC controller to test locos before DCC fitting and avoid all instances of tears before bedtime. Link to comment Share on other sites More sharing options...
Chrissaf Posted November 3, 2016 Share Posted November 3, 2016 You could play safe and test the loco on a 9v PP9 battery or a 12 volt car battery. In fact any low voltage DC source. Link to comment Share on other sites More sharing options...
