    Have a 250xp my dad bought new in 2001 im trying to start. We ran it a little over a year ago everything was fine now i just put a new battery in it and can not get it to do anything.
    Ive checked the plug on the disk compartment along with every other connection at the panel ive got power everywhere but still nothing when i turn the key...is it possible the murphy switch is bad? If possible how can i bypass or check to make sure it is before i buy one? Ive also changed both the 7.5 amp in line fuse and the 14a round fuse on the murphy switch.

    Then it’s probably not the Murphy switch. You gotta chase the circuit for the ignition to the starter to make sure it’s getting juice. Maybe take jumper cables from the battery straight to the starter to see it it will turn over?

    Ive tracked power to the starter but i suppose ive been using a simple test light and i should really see exactly how many volts im getting there

    Ok, but make sure the starter will turn over with the right power. Put cables to it so you know it will turn. In rare cases the gears get jammed on the flywheel but I’ve only heard of that happening on a cat engine on a sterling.

    starter motors get dusty crud that sets hard after you checked the suspect battery key switch to power circuit bang the starter motor with a hammer or take it out work it free lube it

    When you don't have any thing when you try to start it, it usually is the disc hood switch. This is on all chipper with a drum/disc hood switch. You can take the hood switch out of the circuit by joining the two wires together. I don't recommend doing this when you work the machine. This will help you locate the problem. If that's the problem, just get another hood switch and wire it properly. Not long ago, there was a guy who opened the disc hood while the disc was turning and he died at the scene.

    Hope this helps!

    Well i replaced the keyswitch and the plug on the back of it because they both had corrosion on them. Still have the same nostart issue but i did get it to turn over by jumping the 2 connections on the starter solenoid thing on the back of the panel. But still not starting....

    Fuel pump may not be turning on check and see if it is an electric Solenoid that moves when you key it over. If it dont move disconnect the shaft on the solenoid to the pump and move it manually the other way then jump your starter! Sounds like the Murphy if this gets it running.

    When you jump the starter does it Try to start?
    Does this year have a fancy computer on it or is it b4 they started ruining stuff?

    could you elaborate on this please. take two wires out of the circuit and join them? walk me through this please. i'm having the same problem where my chipper wont even try to engage my starter even with new battery, new starter solenoid relay and a freshly rebuilt starter. so if anyone could walk me through bypassing the hood pin and murphy switch, it would be greatly appreciated

    You can simply join the hood switch wires. When it comes to by passing the Murphy switch, it becomes complicated. You could also have a bad relay.

    Hope this helps!

    Check the battery cables for voltage at the end away from the battery they could be corroded internally. You are losing voltage somewhere just check everything till you find the loss.

    Check the starter wire from the ign switch at the starter side to see if it puts out 12v when you crank it . Did you replace the ign switch? Try wiggling wires on the switch.

    ok will do. could you possibly walk me through testing the starter wire from the ignition switch at the starter side? i have a meter, i'm just not good with knowing what to rest when it comes to electric stuff. i have not replaced the ignition switch, will do that as well most likely. but will start by taking the ignition switch off and cleaning all the connectors. thanks

    Start at the ign switch then and see if you can get 12 v to the small wire that goes to the starter solenoid when you turn the key it should send a signal to the solenoid. 12v. I can only guess on your machine the middle post on the ign switch goes to starter not sure? Follow the wires find one that goes to the starter ,small wire.
