If the battery goes dead after winter storage will jump starting have a negative effect on the computer? A freind of mine told me this can ruin the computer.I do plan on un- hooking battery. A trickle charger is not an option. Thanks in advance for any replys.

Not a Vette, but I jumped my old 90 Z24 once and I'll never do it again on a computerized car unless I had to. Needless to say, several hundred dollars later I had a new chip:(. Since then I have considered batteries as a maintenance item and replace them every four years.

In an emergency, stranded, yes I would jump one. Even if you unhook it, some drain will occur.

Why is a trickle charger not an option? If you can't trickle, I would advise getting a nice battery charger and follow the instructions for an out-of-the-car charge before you start the car next spring. The one I have tells me instantly if the battery is dead and in a few minutes will tell me if it is chargeable. I use the lowest charge setting for 12-volts to keep the battery in good shape. Of course, I haven't used my charger since I sold my 71.

Good luck!

Curious as to why trickle charger is not an option. Can't you remove the battery and put it on a bench. Any battery will go dead if not used for 4 months. Better to charge the battery than jump start. Use that as a last resort.

I agree with warp8, it's better to charge the battery than jump, which should really be for emergencies only. For one thing, your alternator isn't designed to charge a dead battery.

Jump Starting

If you do have to jump-start, always hook up the Neg cable first, and unhook it last. This will lessen the chance of spiking the ECM. We jump start a number of cars every year, and haven't had a problem by using this method.

HD2HVETTE is right on. It's the hesitation and funbling connections that creates spikes and can damage electronic circuitry. I jump my vette often and use a two-part cable. You connect the seperate ends to each battery (the Vette and a donor car) then connect the center plug. This eliminates hesitation and also any sparks near the engine compartment. Never had a problem. It's also good practice to be certain the clamps are making good clean contact with the battery terminals.

How would one of those emergency batteries (just a different package battery)
work?

The one I have at my shop has an on-off switch, so you would just hook up both cables securely, turn switch on, and start car. Most emergency battery kits I have seen are similar. Mine is an ATD model, very inexpensive.
