Ferrari Mailing List: Electrical Irritation

[Charles Perry (charles]

So it's a beautiful day in SC and the wife is out so I decide to take the trusty Diablo out for a little fun.

 

However, for the 2nd time in two weeks when I wanted to do that, battery is dead despite being only a year old (Optima Red Top) and on a tender at all times. Last week it at least started with the help of my 200 amp jump cart. This time not.

 

So I take the massive rear wheel off to check the battery. Reading 9 volts out of the car, so I put it on the charger. I check all my connections with a meter to make sure the tender is actually able to do it's job - all good.

 

So then I check the battery terminals and across the + and - I'm reading 8 ohms of resistance with the key out and the battery totally disconnected. Not a dead short, but I believe a helluva lot lower than it should be.

 

So I'm thinking I have a short somewhere, although last week after jumping it the car ran fine and all systems I tried worked.

 

So normally my troubleshooting would start with just pulling fuses and links one by one until I see the short disappear and then start troubleshooting the attendant system.

 

Any better ideas out there?

 

Thanks,

 

- - charles
