Ez boom master switch

[ih1455xl]

Currently wiring in a ez boom in to my sprayer set if for 6 sections all working fine 12v on and off when flick switch all except the master switch wire has no power any ideas ??? Or does it want a power source in to it from sprayer master switch

ezboom doesn't have a master switch signal it just turns each section on or off. On a hardi I used electronics to detect if all sections off turn off the master. What sprayer are you using?

I didn't need a master signal, so didn't encounter this issue. The simplest way would be half a dozen diodes from each section wire - correct way round and joined would give 12v when any one was live. I take it that this is what you'd want. Is there a big current draw on the master? Worst case a relay might be needed.

It's going on a old sands lowline it's turning all the sections on/off so will ignor the master wire only put it on as found it on a wiring diagram

As e3120 says I used diodes and a relay on the Hardi. Happy to help if you want to do it. Can you show us the sands valves what way you have it wired now.

I just assumed the master switch would control the main on/off so not going to worry about that now
