Aigt, Got a 240 DL TWO DAYS AGO

Went to change the battery because i started it using the good optima red top battery in my Monte Carlo and i wanted to recharge the Die Hard it came with. So here's what i did


1. Put in the Optima Red Top
2. Started the car
3. Disconnected the Red top
4. As soon as i disconnected the red top, the thing died.

I took out the alternator and got it tested, it's fine, the VR is fine, the cables are all in good to perfect shape, what else could it be??

WHAT AM I MISSING?

Also, I am new to the forum and VOLVO's, I think the things are awesome, well... when i know how to make them run LOL

Thanks guys

 

Sometimes the Alt doesn't start charging till the car is reved up.
Does it run ok? Does it have a low idle?

Everything might be ok with the car.

Have the charging system checked on the car.

 

It is normal for them to die if the battery is disconnected, but you should never disconnect a battery from a running vehicle, unless you add a load across the terminals. On top of being a storage device, the battery acts as a filter/choke for the cars electrical circuits, and the lack of the battery in the circuit can cause a runaway current/voltage situation for the alternator, and the pulsing dc current and voltage spikes can damage other components . Sounds like the aternator is OK. You will need to charge the dead battery with a charger, or on another car, then install or install as is and jump start.
