Ok, Lesson one learnt.......Do not cut, the Cobalt operating wire.............until you are fully satisfied,it's in the correct position,fully tested.
I know this, I have fitted 30, so far..............
Another point for your Cobalt list....is.....
Check the rails,if using bus,( powered), you have the correct voltage to the frog and running rail,nothing like scratching your head,when rrampmeter reading gives 22.5.v.
Check, un-powered, on Ohms scale, that, the Cobalt frog sw. has fully operated,full closed circuit. 1. on a digital meter
I would, suggest, that you fit, "tails", in every Cobalt,electrical terminal, before fixing to b/board, you may want to do,electrical interlocking,signalling...or...
may decide to fit Richards Cobalt S-Levers........
It will save you cussing, back under there..(and finding,your dinner,is in the dog.....)....also,I note your points are side operated, leave your cobalt wires in place, but do check for clearances,from the sides of your rollingstock, mine were tight...........with Shina..whats it;s.
...
99.99%...Nothing wrong , with the Cobalt............normally the installer.. .. .
