ok well I have about a week to get everything together for the upcoming HC race at VIR. So naturally I have a bunch of **** to do including the install of a kill switch. I was going to have a local speed shop P1, do the install but they are currently booked, so I called up racer wholesale for the switch, and it just arived.

It is there switch 1, http://www.racerwholesale.com/...-Offs

hmm I hope I got the right one, I almost think I should have purchased the switch 4 http://www.racerwholesale.com/...-Offs

If you would be so kind as to look at this thread https://honda-tech.com/zerothread?id=190663, and scroll down 3/4 of the way, you can see the wiring diagram that was sent with the switch that I recieved.

The way I see this is tthat they want you to ground the main electrical feed through the resistor. Am I correct?

 

That looks correct. But I'm still not sure what the resistor is for? My RX-7 has two lines through the kill switch - the battery ground strap and the power lead from the alternator. The ignition is not switched in my setup - killing the alternator has the same effect.

 

Simplier than what is shown, I have had 0 problems the way I do it, so you have my IM..

 

W1 has an opening in the schedule.

Roberts works just fine.

 

How to wire:
Killing battery output: "Big wires"
--------------------------------------
1) Remove wire from battery to starter & discard.
2) Remove wire from battery to main fuse box & discard
3) Run wire from battery to kill switch
4) Run wire from "Output" of kill switch to starter and to main fuse box

Killing Ignition "Little wires"
-------------------------------
1) Find power to coil (On EG it is black/yellow wire coming from ignition)
2) Cut wire and connect one end to one "2" terminal and the other to the other "2" terminal

Grounding alternator / fuse box "little wires"
1) Connect output side of "big terminals" (going to starter) to one terminal marked "1"
2) On other "1" terminal connect piece of wire to supplied resistor.
3) Connect other side of resistor to ground.

What happens: Stated simply as I can:
When the switch is "on"
----------------------------
- The battery is connected to the main fuse box through the switch.
- The power to the coil is connected to the distributor through the switch
- The resistor does nothing - it's not connected to either big terminal

When the switch is "off"
----------------------------
- The battery is no longer connected to the main fuse box
- The power is cut to the coil so the car stops running
- The main fuse box (and the alternator) are grounded through the resistor -preventing any voltage spikes from occuring.

The key thing is to make sure you connect the resistor / ground to the right side of the big terminals - you don't want to ground the battery by mistake.

Note that you never touch any of the alternator wires.

Thanks everybody, I think all my questions were covered.
