Adding a remote control switch for throttle resistor

[rg12]

Hey Dudes,

I want to add a simple remote (one from eBay) that will switch between regular throttle mode (all connected normal) to red wire with resistor through it like so:


* The whole thing will be mounted inside the controller

I have this remote:

I have two problems, one is that the thing requires 12v input and I want to avoid adding a step down converter and the second problem is having the relay switch between two modes and not just open and close the connections in a single wire.

About the 12v voltage input for the remote switch, I was told by someone in this board that I can use a simple AC adapter that receives 110v/220v from the wall and drops the voltage to 12v DC as a step down converter for my 88v battery pack (88v DC doing into the 110v/220v side) and that it works great.
I noticed this thing on eBay:
http://www.ebay.com/itm/AC-220v-10A...587647?hash=item3388fc98bf:g:V9UAAOSwrklVGU9J
But it seems that when the circuit is closed then it takes the whole 88v (in my case) into the load which is something I'm not looking for.

What do you guys thing?
This whole thing got me so confused I need to go eat and rest a bit to clear my mind...

Yes. Looks like it's designed to switch AC power into the load. It makes no sense to be internally wired like that though. The middle contact wouldn't do anything. You would expect the three contacts there to be the three terminals of a SPDT switch of the relay. Well, you could toss $10 at them and see if the crazy diagram is correct.

There is this one.http://www.ebay.com/itm/AC220V-1CH-...1daf98b&pid=100009&rk=1&rkt=1&sd=371196471133 At least this diagram suggests that the relay is isolated.

Why does it have to be remote control? Have you already tested putting a resistor in the power leg of the throttle? You were intending to put the relay across the resistor, so it gets short circuited to remove it?

What's the purpose? Is it to shut off the throttle?

It supposed to be mode 1 - red wire connected normally and mode 2 - red wire through resistor.
It's supposed to limit the bike's top speed from the throttle (checked and it works).

What you sent me seems like it's going to put the 220v into the load side, it's not what I'm looking for...

I believe the diagram is showing external wiring around the device. Maybe I'll get one to run my Xmas lights.
