At 89 with 50,000 miles the original solenoid was replaced with this STANDARD brand. At the first start, the starter continued to work. Pulled out the "S" cable, the engine was still running, finally pulled out the battery cable. Checked wiring was correct. Note: This vehicle does not have "I" wiring. I tapped the new unit several times with my hand and reinstalled it. Started normally, tried again, same problem, starter works. Got the original, no problem. Went to NAPA, bought their brandβ¦
