Some of the solenoids draw 0.5 amp.

But not the ones chosen.

@bezelsanddisplays

Maybe you should read things more closely.

Might do you good!

@bezelsanddisplays

My comment stands. 5 x 500mA = 2.5A

Not doubting that. Just not relevant to this discussion in any way whatsoever.

@bezelsanddisplays

I strongly suggest you 'scope the current through such a coil and you will see a spike when power is applied. A small one maybe, but a spike nonetheless.

You have evidence of this?
