So... now that I've finally got this alarm going in the Torana, I got to thinking... All the warnings that come with new cars regarding using a surge protector when jump starting them... does that apply to our "old girls" if we have electronic devices in them?

Or is it just the engine management modules that can be affected?
Has anyone had any trouble?
Cheers,
Jason.

The other thing which can help is to turn on lights / fans / etc on the "good" car while connecting, to reduce the voltage difference between the good and bad batteries.
Once connected, switch off all extras, start "good" car, then you can start "bad |

Hi Jason,
Yeah mate, it is the same for all cars. In reality, the way I described the process above is how you should do it always.
Cheers...Dave
