Thread: Wiring an EDIC motor and relay?

I used the original Jedico changeover relay that came with the Stage1 engine I used for my conversion.

There's a Isuzu truck wiring diagram in this thread, and the good oil thread has a few other references that you've probably already read: http://www.aulro.com/afvb/isuzu-land...-actuator.html

Pretty sure my T3500 actuator only has 3 wires. If yours is the same I can have a look at mine and draw up a quick circuit if you want.
PM me if I forget

Thanks Steve. My actuator has 3 wires. When I pulled apart the wiring on the truck, it looked to me like the red/white wire was a permanent live to the battery. Any info you can give me about your set up would be great.

Cheers, Dave.

Excuse the poor drawing, but here's what I could work out last night without pulling things apart too much.
Only thing I'm not 100% sure on is the wire colours for the actuator as I have different colours extending the wires to the relay, and the connection plug is hidden in a rubber boot.
I've used the original Jideco relay, but I've done this diagram to use a standard changeover relay.

It would be great if you could test out the circuit on the bench and post/PM any corrections so I can amend the drawing.



As a separate test to confirm which actuator wire is which, with +ve applied to the correct wire, and the other 2 wires to ground, the actuator should repeatedly cycle in-out-in-out ( I think !!).
Also, if you check the continuity between the wires, you'll find 2 wires that show a circuit, and one not connected to either of the others. The one that isn't connected is one of the ground wires. Apply 12v to the wires that have a circuit and the actuator should move and stop. You should then find that a different wire is open circuit - that one is the other ground wire. The third (common) wire is the +ve supply.

Thanks Steve

I'll try to figure all that out and see if I can make it work on the bench first. I'll let you know how it goes and what changes I have to make, if any.

I cannot help it, I have to say it.
My assumption is that the EDIC actuator is a solonoid with 2 separate fields inside which throw either way depending on polarity.

It seems strange that the positive to the solonoid goes to earth with the ignition off,as there would be a constant power drain with the ignition off.

If you connect both sides of the relay to earth, you are running all the wires can carry to earth, so the relay will probably lose its smoke.

to the correct wire, and the other 2 wires to ground, the actuator should
repeatedly cycle in-out-in-out ( I think !!).

I would just connect it up to the battery as per the diagram eg positive to the EDIC and both earths to the relay (87,88A), then to earth on the
other side (30 and 85) , It should clunk down? as soon as you connect the wires then touch the IGN wire (86) to the battery positive terminal. it should then throw upwards? to open. When you take the ign positive off it should close I assume down.
It makes me wonder whether blue white should also be switched by a relay activated on the Acc position.

This is a Toyota one which has a second relay.
