Elecrical cut off/battery relocation

[Guest zfan]

The other night when going to the track, while in tech inspection the guy doing inspections said because I relocated my battery to the back of car I must have external emergency cut off to all electrical?

 

I bought a Moroso battery cut off for back panel of car. My question is has anyone else had to do this and if so how did you hook yours up?

 

I just don't want any screw ups on my part as I'm no electrical guru.

I've done it but it needs some reworking

 

You're supposed to hook it to the positive cable from the battery and then route the other side to the rest of the system. A smart person will immedietly realize that in a rear-end accident, as often happens on the street, this will INCREASE the risk of fire since that cable will likely short Thinking I would be smart I hooked it to the ground side and then hooked the positive side to another switch that's within reach of the driver. Grounding a goround won't cause a fire

 

Just one problem - when you kill the ground using my setup the car keeps running off the juice the alternator provides! It won't start with that switch off but it won't die when it's popped either. I think I'm going to have to run a relay or something in order to make this work right but haven't done it yet. PITA!

 

Just to be clear - the NHRA rulebook does state the switch must be there and that it's supposed to be hooked to the positive side of the system. I just figured that so long as the sucker died properly they would neither care nor check Shame it wasn't that easy...

I bought a 4 pole switch from IO port racing supplies 1800 949 5712 .This enabled me to hook up the postive battery cable and use the other poles to disconect the alternator/(i am shutting off the injector drivers of my SDS via a relay). this kills the car in keeping with NHRA rules. It`s just funny i had to go to a roadrace supply place to get the correct switch.
