    few of my gauges in my Pete were not working and I saw that some guy said jump the accessories relay and all the gauges started working.my question is by jumping the relay and everything works does that mean that the relay is bad r could it still be something else.gotta drive 3 hours to get it so just want to make sure that the problem,also is there a way to check a relay to see if it’s bad
