1989 Ford F250 7.3L Diesel. Bat light came on then smoked the VR

I have a 1989 Ford F250 4x4 with 7.3L Diesel. The bat and break light came on, first bat, then break. I let the truck sit for a day and the batteries were dead. I hooked up my charger, waited for a few minutes, and then tried to start the truck. White smoke came out of the voltage regulator. Was this caused by a bad voltage regulator, alternator, or batteries, or a combination?
Thanks

Thats a guessing game, but first, if the battery light was on, that means no alternator output. So recharge the batteries and be sure they are good, Then replace the alternator. If the batteries and the alt are good, and the battery light is off, then all should be OK.

03 Taurus, battery light comes on. R&R bad alt &


You may have a a/c voltage leak comming from the alternator..If its a rebuilt alternator sometimes you get a bad one ..But make sure all your connections are good ecspecially the small wires coming out the back ..These are the field and sensor wires..Plus make sure all your grounds on the vehicle are not broken or missing..You can have good voltage but it may have a drop going to the computer because of a ground and cause the light to come on

Car will not start


Was it a sudden event or had it been turning slowly ? If it was turning sluggish or slow it is probably your starter. You will probably neded to replace it.

1989 diesel not starting


This makes me think that there is a problem with the ignition switch. It sounds like it is making the connection for the truck to run when it is in the "on" position, but not when it is in the "start" position.
