You should do what Stan is suggesting to get an idea on the lamp load. Here is a thread that talked about a similar problem. Apparently, per pictures in this thread, both the 10 and 14 volt coils are protected by a 4 amp breaker, even though they are rated at 1.5 amps. As several mentioned above with ohms law, if this is happening with lighting only and not a solenoid, then you have too much current for some reason. Current will be lower (correction) at 10 volts than at 14 volts, all else being equal. Must be something going on, the lights on those platforms are small. Hard to believe they are 4+ watts each?
