Question about 2001 Volvo V70
Yup, grounding problem.
There is a grounding strap from the engine to the chassis. It is either loose, corroded, damaged, missing, or otherwise not making good contact with the engine or chassis. If you can't locate it, then ground has been using the "pigtail" wire coming off the negative battery side.
If you had the battery or cables services recently, then the wrong negative cable was installed. Installing a ground strap (AutoZone $8) from engine to chassis is better anyway.
