2016 Coronado glider, intermittent no crank. It might go for days with no trouble. I’ve tested the ignition switch itself to see if it has good contact through the start terminal and it does but no start signal at the mag switch. I’ve been using needle nose pliers to jump the terminals to get it to start. Any help would be appreciated.
Thanks

I don't know the circuits of your truck. If you have power out of your ignition switch to the mag switch. You have to jump the mag switch terminals to start.
I think your mag switch is bad.
Or do you mean you are jumping the terminals on the starter solenoid?
Did you disconnect the wires and clean them. Corrosion penetrating the terminal ends could be your problem or a broken wire inside the insulating jacket you will not see.
Good luck.Oxbow Thanks this. -
