Tim Larkin Posted June 18, 2018 Share Posted June 18, 2018 I pulled into the shop today to charge the A/C I shut the truck off and now it won't start. There is no power to the switch if you turn the switch to the start position it will cycle like it is ready to start then it goes dead. I'm looking for ideas to check Thanks Tim Quote Link to comment https://www.bigmacktrucks.com/topic/53596-truck-wont-start-08-granite/ Share on other sites More sharing options...

Dhitman Posted September 12, 2018 Share Posted September 12, 2018 I have that same situation but the tractor will blow the fuse and it will shutdown. I’ve inspected the wiring and using a test light to the positive side of the fuse I get power and when I test the other side I can hear the ignition relay clicking. I replaced the relay and now it works but I need the get to the root of the problem. Anyone have any info?

41chevy Posted September 12, 2018 Share Posted September 12, 2018 Relays do go bad. The coils short and or the contact points burn and pull a high resistance, over load and pop the fuse.
