Dead Batter = No Engine Block for negative cable

Mike's got a great site! I now am thinking of going with an Optima. I have put them in my other cars. Cheers.

Only the last connection will cause a spark.

Hook up both cables on the Boxster's battery posts.

Hook the + cable to the + post of the other vehicle.

Attach the - cable to the block of the other vehicle.

I bought the Costco battery (Costco Kirkland Group 48) as per Mike Focke's page and it fits perfectly. The way I get around with having to re-enter the radio code (since I didn't get it from the previous owner), is to connect the terminal cables with another car's battery using the jump cables. I used the negative cable and grip to the bolt on the car body. And quickly disconnect the positive cable cramp, grip it with the positive jump cable. Then I was able to remove and replace the battery, and reconnect the positive side first. When all is done the radio was working as before.

Find out that battery code. It's bound to bite you eventually.

ditto - I needed my radio code at 1am after doing the Ipod cable install inacurately...the first time....grrr. Renntech.com came to the rescue 48hrs later with code option. Dealer wanted $150 to dig through the computer to find it. LOL!

Hi team -
I just went out to jump my Boxster. I had to do jump it once before and it worked fine when I left a door open all night.
So I hooked up the cables and turned the key and just a bunch of clicks and lights and NO fire. I wait a few minutes. Check the cables. Rev the running car. Turn my key and same. No firing. Left the car hooked up to the other car for ten minutes. Still nothing.
Ideas?

Hey EM,

I see that you've checked the cables, but it's the only thing that I can think of.....

Can you describe how you've hooked up the cables???

+ (other car) to + (your car)
- (other car) to ground /bolt/metal (your car)

Also check to see that you have the alligator clips on clean contact points / connectors....if there's any corrosion, make sure to wipe it off. If you're using a bolt or nut (from your vehicle) that has paint on it as your ground, you might want to take some of the paint off so that it's completely metal to metal.

...If you have an automatic, sometimes the car won't start if you don't have it in PARK (P) all the way.

Good luck! Let us know what happens.

Hopefully, someone else can chime in with other ideas for you!
