In the other case it proved to be ballast that was causing the issue because the fixing PVA was bridging across the rails
I experienced an even weirder reason on several shows: High temperatures and/or humidity. This could cause ( and did in my case ) occasional bridging of the section gaps...? Next day with lower temps and dry weather, the problem was gone.
Here is another option to "tame" input spikes. It however does not help in case of bridging ( as an extra resistor does not )
