rhtrudder Posted July 25, 2018 Share Posted July 25, 2018 just fitted a new battery in my plane , 914, and noticed after fitting the positive that when I touched the negative it produced a small spark , everything turned off, where would I be loosing current.

apm Posted July 25, 2018 Share Posted July 25, 2018 From the one thing that is not off. Do you have a multimeter handy & know how to use it? Link to comment Share on other sites More sharing options...

cherk Posted July 25, 2018 Share Posted July 25, 2018 just fitted a new battery in my plane , 914, and noticed after fitting the positive that when I touched the negative it produced a small spark , everything turned off, where would I be loosing current. Maybe Clock ( if fitted) or charge current for electrolytic noise suppression capacitor ( if fitted) ?? Link to comment Share on other sites More sharing options...
rhtrudder Posted July 25, 2018 Author Share Posted July 25, 2018 It does have a cap fitted and I did wonder if it was the culprit, doesn’t seemed to have lost any voltage after two days so maybe okay 1 Link to comment Share on other sites More sharing options...
Lucky01 Posted July 26, 2018 Share Posted July 26, 2018 Happens with cars mate, First connection with a new battery the customer thinks that they have a drain and that you should find it for them for free (they only came in for a new battery), With an inline ammeter you can see the spike in the initial connection - then watch it plateau out.
