HOW FAR CAN YOU DRIVE WITH A BAD ALTERNATOR

My alternator is bad and is not charging the battery. Have to have the alternator replaced. There is a brand new battery in the car and fully charged. How far can I drive my 348 with all systems off in daylight. Want to learn if I should have the car towed or whether I can drive to the shop to have the alternator replaced. Also does anyone know what kind the original alternator was. Thanks for your help.

That depends on how far the shop is. Is it only a few miles and without traffic, or is it 30miles away through city streets ect.

 

maybe keep a charged booster pack handy in case you go for it and the battery gets weak?

 

Maybe the better question is how long can I drive it. 10 minutes? 30 minutes? 45 minutes or longer? Anyone have any idea and also the type of alternator?

 

How far is the shop???? One mile, two miles, twenty miles?

 

10-14 min I would say not much longer

When the voltage drops below a set point the ecu shut down

Higher the rpm the more juice the ECU will use so drive at low rpms

 

Lol, forums

 

Until the battery doesn't have enough juice. No real way to say until you drive it and tell us how far you made it..

 

It depends.

 

On a fresh, new battery with everything turned off, probably an hour.

No guarantee.

 

I made it a hour on my DD with all the accessories off. But it was a 4 cyl.

 

I made it from Albequerqe to Denver with 2 stops to recharge the battery for an hour in 2012 with my 1995 F355.

 

First Ferrari all electric?

 

I told Dr. Helms to get the alternator fixed asap when I got back I was not a fan of the hybrid 355!

 

Further downhill

 

I can vouch for 3 miles with a brand new battery fitted just to get me home (whatever level of charge that would typically come with?). I did this about 8 yrs ago when my ac delco alternator decided enough was enough (1991 348 ts).

 

if indeed a new battery fully charged.

you can drive for at least an hour

 

Less miles with an F1 car as it has an extra computer to run

 

why not call a tow truck if your that worried about it

 

Call a battery shop.

 

Car will be towed. Thanks to everyone for your response.

 

about an hour max keep everything off realy important

 

Does a dash light (battery) show up when the alternator is starting to fail or does this usually come as a surprise with gradual symptoms of a slow turnover, etc...?

 

My alternator on 348 went and I drove 90 minutes home , a/c off radio then drove to friends lift next day ...

Once in my DD I drove to work for 3 days

 

Why is this thread still going? Car is already at the shop. Might even be back home by now
