Wizzard Mag Shutoff Switch Question

I Used To See The Big Shutoff From Wizzards On Mag 44s, Now They Sell It With A Solenoid.i'd Prefer Just The Switch, How Does It Hold Up? Will It Last Or Do I Have To Use The Solenoid? Rather Not Have The 12 Volt Draw And Extra Weight If I Could Do Without It

 

Just bought what you are talking about, would like any input (pros/cpns) b4 I install! Thanks Tim

 

I Know A Few Cars(mostly Mcamis Built) That Have Just The Switch,but Dont Know How It Lasts. I Know The Solenoid Is About 30.00, Paid 160.00 For The Switch Thinking I Could Run Just It To Make The Wireing A Lil Neater.

 

Mike,

Gonna have to disagree with you on that one, we've been using the plunger switch for 4 years with a pro mag 44 without a single problem on our TAFC and our old TAD.

Shawn and the rest,

DO NOT start the car with the switch, use grounding wires on the coil and you'll have no problem. I just don't like the idea of the air switch from MSD, more things to leak and malfuntion. The plunger switch it one wire to coil +, grounds through the switch body to the chassis.

Just keep on top of it like everything else, change the switch every so often (we changed our out for a new one after 2 years of service and still works fine, just a spare).

Good luck!

 

Just to clarify, I didn't mean the Mallory plunger switch...we've had issues with those, I've heard mixed reviews. The one I thought Shawn was talking about was the one that Wizard's sells, the SAE plunger switch (round body, not square). We got ours from Wizards, though Good Vibrations Racing in Cali sells them too.

Nathan- you sure you got that switch from Wizards? LOL! Good luck next weekend in Mission- bob

 

Switch

Nathan The One I Got From Wizard, Is The One He Has Listed In His Catalog, A Large Red Pushbutton, Has A Aluminum Faceplate And Plastic Body,clear In The Back Where You Can Visually See The Contacts. I Know Tim Mcamis Sells Them Also For His Cars.
I'm Not Sure If It Is A Mallory Switch Or Not

The swiych with the big red knob and clear back can be bought from grangers. We have used this swich for years and no problems, we use it for starting and shutdown. Use it on a 44. Priced at about 80.00$ Mike

 

Haha, Bob I meant the one previous, don't worry - I remember I got that one from you! Thanks!

 

Kill (er) Switches

THERE IS A NEW AIRSWITCH AVAILABLE. YOU CAN GET A HOLD OF SEAN BROWN AT DAVENPORTS. VERY NICE AIR SOLENOID. EASY VISUAL SIGN TO TELL IF IT IS ON OR OFF, REAL NICE PLUG YOU PULL WHICH ELIMINATES THE ALIGTOR CLIPS AND WIRE. LOOKS LIKE A NICE QUALITY PART. I HAVEN'T PUT IT ON YET, BUT SEAN SAYS THE ONE ON HANK COOLIDGES CAR IS OVER TWO YEARS OLD WITH NO ISSUES. IT IS KINDA EXPENSIVE AT $285. I HAVE USED THE JOHNNY WEST (MSD) AIR SWITCH FOR MANY YEARS WITHOUT FAILURE, ALTHOUGH WE DON'T START THE CAR WITH IT AND I SHUT THE MOTOR OFF WITH THE FUEL NOT THE SWITCH. REALLY JUST MORE OF A SAFETY DEVICE AS FAR AS I AM CONCERNED.

IF ANYONE WANTS A SPE SWITCH LIKE NATHAN'S PICTURE. EMAIL ME. I HAVE A BRAND NEW ONE, NEVER MOUNTED THAT I PAID 95.00 FOR FROM SPE. I'LL INCLUDE THE SHIPPING FOR 75.00.

MSD kill switch with six shooter

Clint,
I use a standard good quality single pole switch. I checked with MSD and was told it was ok to do if you have a six shoother. The swith furnishes power to the six shooter which only requires about an amp. I was concerned about wheather it would shut the engine off under power but last year had the battery wire that feeds the six shooter switch voltage come off at about 400 feet and it killed the engine instantly. With no power to the six hooter the mag will not have any output. I use the same switch to arm the #1 channel on the six shooter. I used the solonids, and also the Mallery switch. Had problems with the Mallery after a while but figured out I did not either. I checked with a couple of TF guys and they some do the same thing. I have never had a problem associated with doing it this way to my knowdlege.

This May Sound Stupid But I Was Told To Never Shutdown The Engine With The Mag Kill Switch Unless Needed Because It Loads The Engine Up With Fuel Im No Expert That Is Just What I Was Told. And I Read That Some Of You Use The Kill Switch To Shut Down At The End Of A Run We Have Always Used The Fuel Shutoff To Kill The Engine What Is Really The Correct Way Or Does It Matter

 

kill switch

Hi Nathan
I can confirm that the kill switch in your old TAD is still working fine! As instucted by Serge when he came down to New Zealand to help out in our fisrt races, we also start car with the ground wire across the terminals and shut off the fuel for shut down on a run.No problems what so ever all season.
Think I should by a spare though just in case.Seen Serge lately?

Capacitor

You are right Will when I changed over to the kill switch on the six shooter I removed the capacitor.
The other post was also correct in that you would not normally shut the engine down with the kill switch. You first shut fuel off and by the time you hit the kill switch the engine is either dead or almost there.
