Car Forum / Volvo Cars / October 2006odd electrical problem
Just got my 95 850 for $2500 as is. Didn't realize there were this many problems. Main one right now is related to the charging system. When the engined is reved high while the car is driving, the lights get brighter, the directionals blink faster, and a sulfuric smell is emitted from the engine compartment (battery acid? The battery has an overflow tube). Any ideas on what this might be? The alternator, voltage regulator, or main computer? >Just got my 95 850 for $2500 as is.

At the battery posts. You should have about 14+ volts at idle and not much more at 2500 RPM. If it surges way up at speed, the regulator is faulty. If the initial reading is well below 14 volts, the battery is the likely suspect. Chuck Fiedler Nothing but Volvo since 1974 > Just got my 95 850 for $2500 as is.

The alternator, > voltage regulator, or main computer? These are typical symptoms of a failing battery.

Also check if the ground is ok.. maybe the wires are not properly connected, then you will get "funny" electrical issues, wires that are melting, etc. |
