I have a 99 volvo s80 T6. It has 122,000 miles. The other day I had to jump my dads truck and everything worked fine. After I jumped the truck Iturned my car off and drove the truck for about 2 hours and came back to the house. When I got home I tried to start my car and all I got was a clicking sound. I hooked the jumper cables up and when I turned the key to start it killed the truck. Now both are not working. All other elec. is working fine on the s80. Battery is good. I took the starter off, bench tested it and I also took it to autozone and it is fine. When I put it back on the car and tried to start it I still got a clicking sound under the hood. Any ideas?
