You have a bad ground somewhere in the car. This ground problem is common in Sportages. You will need a electric diagram of a good mechanic to locate the bad ground.

scuffed all grounds i could find under the hood took generator off tested it was BAD put new in $150.00 runs fine now was only putting out 8.53 volts
