Why can I not find a shut off switch for the side mounted terminal battery ??? Tired of un screwing the + cable during storage and then retightening it to run the car. I only see top post battery shut offs at Pep Boys, O'Reillys, Auto Zone etc. Any ideas ???

Why are you unscrewing the postive side anyway? You should be disconnecting the negative side of the battery first.

The positive side is easier to get to.

This is the one I used: Side Post Battery Master Disconnect Switch

Well, the electronics don't care which is easier to get to. It's not a positive ground system. The negative cable should be disconnected first, for your own safety, and the safety of the electronics.

Indeed. Typically considered unwise to remove only the positive cable.

Pretty sure the electronics don't really care either way. Disconnecting the negative first prevents one from shorting a wrench to the chassis when removing the positive side. Doing that with the negative attached makes big sparks and melts a good wrench.

The electrics might care a little less in the Fiero… until you touch the wrench to a ground. But you'll feel it too.

If you use an insulated wrench to remove the positive terminal no bad things will happen. But Lawyers will always advise to remove the negative first to avoid lawsuits.

They make a shut off for top and side mounted posts. You just turn a green knob to 'disconnect' it. Some even have a small wire with like a 5amp fuse to keep your ECM/radio presets while disconnected. You can also get a race car shut off switch from Summit or Jegs...their required on race cars. You can mount it like under the seat or dash.

IMO, best cut off switches are those where the battery ground cable runs to them (then to engine ground) and the switch is solidly mounted to a bracket. Those types of switches are NRA legal. Never had good luck with battery mount switches. With time they can work intermittently. If you regularly use the switch for anti-theft applications, you can put a fuse holder and 20 a fuse across it to keep the PCM from resetting. The engine will not start and will blow the fuse if you try but it can be a theft deterrent.

They make a remote battery disconnect, that can be set to automatically disconnect the battery after a certain period of rest, or when the battery reaches a certain voltage. Can be turned on/'off remotely, or with a switch in the car. Check on Amazon- they have several different models.
