What is this?
I'm having a problem with my 1994 Ford Ranger with a 4.0L V6 engine. I wasn't able to start my truck. I checked the battery voltage and found it was 10.6V. The water level in one of the cells of the battery was slightly low so I added some distilled water. I noticed that the part shown in the photo starts and stops. What is it and how do I fix it?
Thanks,
Mike
