EVOX IDLE Board Explanation

This brief talks about the evox idle board and describes the SA200 wiring in my own understanding and words.

in my opinion, at this time, the SA200 in its minimalist form has four wires:

  1. DC exciter positive (often black)

  2. DC exciter negative (often red)

  3. second wire tied into DC exciter positive heading into the shunts

  4. wire from the shunt wire heading to the remote switch

Lets start with the DC exciter positive and negative. Coming from the barrel, you will have two wires. colors dont indicate anything but they are typically red and black. with a dc multimeter and the machine running, the wire measuring positive is DC exciter positive and the wire measuring negative is DC exciter negative.

Now that you have identified those two wires, hopefully you have only two remaining wires. I call them DC exciter positive to shunt and shunt heading to middle of remote switch.

In SA200 setups with an idle board. the DC exciter positive connects to the LINE 1 of the idle board.. On that same spade, a new wire is connected grabbing that power. That wire is the DC exciter positive to shunt.

In SA200 setups with an idle board. LINE2 on the idle board has a short wire feeding power to one of the prongs of the receptacle for you grinder.

While were on it, the same receptacle other prong would be DC exciter negative. Often you’ll have the DC exciter negative connect here and have a second wire shoot up to one side of the machine rheostat.

On the evox idle board, IDLE on the idle board accepts the other wire of the solenoid for your throttle.. On a side note, the other side of the solenoid grabs voltage from the oil pressure switch or something similar.

Wiring Setup:

  1. VBAT battery voltage (yellow wire from auto idle toggle switch)

  2. REED weld reed switch one or both sides (optional spade if reed returns to board)

  3. SHUNT (top prong remote switch))

  4. LINE 2 (board to fuse for receptacle)

  5. LINE 1 (positive exciter)

  6. IDLE (white) (ground of solenoid)

  7. SHUNT (top prong remote switch)

  8. DC - NEG (dc negative exciter)

The Wire coming out the generator is the blue shunt wire. The blue shunt wire if you have a remote switch, goes to the center prong. Then a new wire goes from the bottom remote switch prong to one side of the machine rheostat. A new wire goes from the top remote switch prong to the SHUNT spade on the evox idle board.

Your board grabs SA200 battery ground through board posts. As well, my screws are one size bigger than oem. So a slight enlargement of the two holes may be necessary

These points are all just pieces of information. Well adjust this tutorial accordingly
