battery mounting,kill switch Q?
 

right at the moment this rambler is a bracket car but I don't want to make it stocker-illegal.

#1 does the trunk battery have to be in a box or can it be bolted to the trunk floor?

#2 I'm running a delco internal reg alt, big red wire gets jumped to one of the regulator connector and off the charge post to which side of the battery cutoff switch?
I'm thinking the battery side of the switch....

Re: battery mounting,kill switch Q?
 

The battery has to be secured by something other than a cloth strap or factory style J hooks. It can be bolted down in a box or bolted to the floor by metal straps. Most use mounting kits consisting of a plate with threaded rods that hold a top plate over the battery. Think Jegs, Summit or Budget Fabrication aka DYI.

The battery cut-off should interrupt the main power circuit to the car so that throwing it kills the engine and all accessories especially the fuel pump.

Battery positive connects to one pole and the line to the car connects to the other. Most of them can be rotated so that they can be mounted upside down if needed. It's just a gate switch and does not really have a battery side that matters. Just wire it so that Push is Off.

The charge wire from that alternator is not connected to the kill switch. This caused me a problem with the alternator draining the battery with the car off so I put a breaker switch in the alternator line in the cabin. It lets me shut off the feed from the alternator when the car is off. I wired my volt meter directly to this breaker. With the car running and the alternator set to charge the gauge tells me battery power. If I throw the switch and break the charge circuit it tells me the alternator output.

I don't think he meant it that way. I think he's asking, Does the alternator connect to the same side of the switch as the battery, or to the opposite side of the switch?

I'm thinking the same side as the battery, that way when the switch is off there's no chance that the alternator will continue to power the engine and fuel pump. But I don't know for sure, it's been a very long time since I've run a car with a trunk-mounted battery.

Re: battery mounting,kill switch Q?
 

That would be correct. I tried connecting my alternator to both sides if the switch to solve my battery drain problem and connecting it to the car side produced run-on. I saw no difference between connecting the alternator to the battery side of the switch and the battery positive itself, so I went with the battery pole because there's more room up there and I'm not sure Tech wants anything but the battery connected to that switch.

If an alternator shuts itself off correctly, it can be connected to the battery side of the shut-off switch. Mine won't.

Keep it simple, safe, and NHRA legal, get a double pole disconnect.

Which one of the small post do you connect the alternator
charging wire on the 4 post switch?
Thank You

Re: battery mounting,kill switch Q?
 

The one in the link below is similar and has an instruction link. The battery positive jumps to one of the smaller terminals and the alternator connects to the other.

If wanting to make Stocker legal battery has to be in stock location. You can run a second battery in trunk but they have to be seriesed together.

Re: battery mounting,kill switch Q?
 

Series yields 24 volts, I think you mean parallel, positive to positive, negative to negative.

Re: battery mounting,kill switch Q?
 

There are stockers running a series set-up using 6 volt batteries.

Re: battery mounting,kill switch Q?
 

I have a battery in the trunk which runs the ignition, fuel pump
and the starter. I have a shutoff switch in the rear for that battery
I also have one under the hood that runs the accessory like water
pump and fan, lights, I never seen in rule book they have to be hook together. Thanks for the help with the switch.

There must be one master cutoff that disables all electrical functions of the car. Running two batteries, one in front and one in back is not a usual setup and isn't addressed in the rules. The idea is for rescue personnel to be able to kill all electrical flow in the car from one switch on the outside in the event of an accident. Your running stuff under the hood could start a fire in the event of a fuel spill.

This is in the general Section.

"8:4 MASTER CUTOFF"
Mandatory when battery is relocated, or as outlined in Class Requirements. An electrical power cutoff switch (one only) must be installed on the rearmost part of each vehicle and be easily accessible from outside the car body. This cutoff switch must be connected to the positive side of the electrical system and must stop all electrical functions including magneto ignition. The off position must be clearly indicated with the word “OFF.” If switch is “push/pull” type, “push” must be the action for shutting off the electrical system, “pull” to turn it on. Any rods or cables used to activate the switch must be minimum 1/8-inch diameter. Plastic or keyed switches prohibited. Switches and/or controls must be located behind rear wheels on rear-engine dragsters.

well, now that we have the switch issue solved, how about the battery box?
does it need to be IN a box or can it be in a tray bolted to the floor?

Re: battery mounting,kill switch Q?
 

See 8-1 general regulations in box or strap down with metal strap

Re: battery mounting,kill switch Q?
 

Does anyone know when the front mounted battery in Stock Eliminator will become optional??????????????????????

Re: battery mounting,kill switch Q?
 

When the alternator goes away, Bob. Not long.
All these switches and levers and cables are looking more and more like Bracket Two every day.

Meanwhile, what's wrong with one of these?
