Electrical problem
2000 Dodge Caravan All Wheel Drive Automatic

Hello my 2000 dodge grand caravan. It started running funny while sitting in the driveway the battery light came on and the car died. I replaced the battery and the car started up but the battery light was still on. It had been making kind of a grinding noise by the belts. I don't know if it the alt or what? The serpentine belt had come off twice before but is intact and spinning fine but thats where the noise is coming from. Don't have money to take it in please help!

The battery light means the charging system has a problem, not the battery. First of all, use a digital voltmeter to measure the voltage across the two battery terminals while the engine is running. It must be between 13.75 and 14.75 volts. If it is below 13.5, it will not fully charge the battery while driving.

If you do find low voltage, the most common cause is worn brushes inside the alternator. They can be replaced, in some cases without removing the alternator from the engine. Also check that the pulley is actually spinning. Since it was making noise, the bearings could be seized. Usually the belt won't last very long when this happens, and it could be related to the belt coming off.

Hi guys. I posted an answer to the other question. Worn brushes are a real common cause of intermittent operation. The assembly costs around ten bucks, and on some models can be replaced without removing the alternator from the engine. You might not find this at an auto parts store. Starter/generator re-builders will have the assembly.

Thank you very much for your help! How would I tell if its the alt? The belt spins so could the bearings still be seized? Thank you!

The brakes are buddies with the charging system and wanted to show their support for the alternator!

Rear steel lines rusted out. And thanks dodge for using unstandard FINE THREAD on 1 line and for the backwards mounted valve assembly combined almost guaranteeing a STRIPPED hole!

That's not even a temporary fix. That's a rolling accident waiting to happen.

Actually the hidden rusty lines were also a rolling accident as you say as my wife experienced loss of braking power when they leaked! Think how many millions of drivers may be driving in the same condition!

Yes, and think of all the innocent people they may hurt because of their irresponsibility. That's why cars have bright red warning lights.

What I meant was there are rusting lines that have NOT leaked yet and so no indication is on the dash until suddenly they unexpectedly leak and lose braking power! Even so I think its rare that this actually causes an accident! And when the lines are hidden from view I would say many inspections dont reveal any problems! But there is NO way to prvent this unless manufacturers use stainless brake lines! Could even be GOV mandated!

This isn't a debate about how dangerous brake failures are. This is about the conscious decision to drive a vehicle on the highway knowing there are no rear brakes. That will land you in jail if anyone is hurt.
I don't intend to discuss this any further.

Yes well it was an economically driven decision cant fix back brakes until money and time is available. Cant go without use of vehicle until then. Not having back brakes poses no great risk except in some once in a million set of circumstances. The added stopping power of rear drum brakes is negligible. The fronts are incapable of locking the wheels under normal conditions.

Keep in mind almost all minivans have split-diagonal brake systems that put one front brake and the opposite rear brake on the same hydraulic circuit. I wasn't following this discussion, but if you have a leak in both rear brake lines, you won't have any brakes. That gets to be real hard on shoe soles when trying to stop like Fred Flintstone had to do!
