Thread: 1989 Hitachi EX200

Nothing happens when you turn the key. And also, thanks so much for posting a diagram for me :-) will help alot!

Not sure if the 200 is the same, but about 9 years ago I was running an '88 EX150 that did the same thing, ie. nothing happened when I turned on the key. Turned out to be the master relay beside the batteries. What you're looking for is a big black round thing about 2 1/2 to 3 inches in diameter with 2 big wires and 2 little wires going in and out. This one said "NEW ERA" on top in big letters. I just simply took...

I have the complete workshop manual. What section of the hyd. do you need the manual does not show a complete hyd schematic only sections.

or maybe can help me by pointing where to look for the diagram? cause i tried calling my local dealer and they dont seem like they're gonna help. Thx

If "nothing happens" when turning on the key. No lights nothing. Then start by looking at the Battery Relay (basicaly an electric night switch). In the battery compartment. While this may not be activated therefore not allowing power downstream it is usually not the problem. There are 2 fuseable links coming off each of the two bigger studs. (battery cable also connects to these studs). Check to see if one of these are not...

The comments on the battery relay are spot on. I have also seen issues with shorted out glow plugs. Basically if you look at the glow plug connection bars you will see a burned spot in a dry climate or a rusty spot in a wet climate. Basically one of the plugs shorts out but enough current goes through the bar to burn it before the fuse burns out. I've seen it enough that I check the bars every time I check the engine oil. Also if the fuse...

Let me know when you need to sell this excavator, i probably buy it.

Been there, done that. We owned a Deere 690D in the past and still have our 490D. And everyone is right about the problem being the battery relay. But do not bypass it for very long, as there are parasitic loads that will drain the battery down when it is shut down for a few days. Thats why they have a battery relay. Learned this the hard way.
