Case 450 won't start

[carrotstick]

Hi there,

I have a 70s Case 450 that seems to have died for good. Over the winter the starter solenoid fried and I left it till now. I've finally gotten around to replacing the solenoid but now it's not turning over nor does it seem to be drawing any power from the battery at all. The battery is fully charged and the wiring to and from the starter and ignition appear to be fine.

Now, I got the bulldozer with the property I bought a few years ago and have no history on the maintenance or upkeep. It's only used for plowing snow in the winter so it's parked for 7-8 months out of the year with occasional starting and idling for general maintenance and lubrication. Not a single gauge on the dash works but it's ran fine for the 3 years I've had it until now.

Any help would be much appreciated.

Welcome to the forums.

1. Check and clean both ends of all battery cables, then try it.
2. Next if it doesn't turn over. With it in neutral use a jumper wire to jump between the battery cable terminal of the starter solenoid and the small start terminal of the solenoid. If this makes it turn you have a wiring or switch problem between the switch and solenoid.
3. If it didn't turn with the jumper, you can check battery voltage at the solenoid battery cable before cranking and again when trying to crank it. The voltage should drop at least 2 - 3volts when cranking. If it doesn't drop, I would pull the starter and have it checked. If the voltage drops, but the starter doesn't crank the engine, I would pull the starter and try turning the engine over using a large screwdriver or bar on the ring gear to see if the engine is stuck. If it bars over, have the starter checked.

Just some things to check and try. Others will be along with more.
