richard_croft Posted July 9, 2019 Share Posted July 9, 2019 Has anyone ever measued the stall current of a Lima loco? I'm interested to know if a TTS decoder can be safely fitted to a Lima class 37 but im not sure how to measure it. Thanks Richard Link to comment Share on other sites More sharing options...
Chrissaf Posted July 9, 2019 Share Posted July 9, 2019 Firstly, to test the 'stall current', any decoder that might possibly already be fitted should be removed. Do not rely on 'DC Operation' enabled for a 'stall test'. How to do a 'stall test' is documented here.https://www.brian-lambert.co.uk/DCC_Page_1.html#Bookmark10.

Howbi Posted July 9, 2019 Share Posted July 9, 2019 /media/tinymce_upload/53e278463dd63ddef2367ce877fcc841.png Place loco on track up against buffer, wire up meter as per instructions in it's manual for DC current reading. Set selection knob to 10 in the Amp DC section on the meter. Turn controller up to three quarters speed so loco wheels spin up against the buffer, observe reading then press down on loco to force wheels to slow down BRIEFLY and note reading.......for example, on an O gauge Terrier the readings were 0.25amp while pushing against the buffer and 0.5 amp when pressured to force the motor to nearly stall......hope this helps.......HB Link to comment Share on other sites More sharing options...
