Since you don't know the history of this 425 you need to srart at square one and that's the battery. Have it load tested and check the connections on both ends of both cables.

Then the fuses and connectors one by one.

Getting the John Deere 425 Technical Manual will be a big help. It will have a detailed schematic and diagrams and troubleshooting procedures for the sub-systems.

brand new battery so i dont think thats the case ill check connecters now, i heard the solenoid connectors go bad sometimes. thanks for the quick reply

New batteries don't mean good batteries. You'd be surprised how many new batteries are sold that won't pass a load test.

I never buy a battery that I can't see load tested before my eyes and doing that has saved me a lot of time and inconvenience in not having to return new batteries that develop problems.
