Hi, I am having the same problem like spitzair , my computer just fried last week.
I am trying to fix the computer but could anyone help me with the components that needs to be replaced.
If I have to buy a new one, how much and where can I buy this?

I'm talking about;
- R1 resistor what type and how big (can't read anything)
- B1391 transistor (can't find any here, is there a replacement)
- D2101 transistor (can't find any here, is there a replacement)

Here are more information

Hitachi

Numbers on the computer

Ps. tomorrow I will post some pictures

You cannot fix it by yourself due to part unavailabilty and test machine. You must have to buy a new one.

where can I buy one, on the net I can't find any.

I bought mine at Wajax for $1700 cdn. I believe rgl726 can get you one for a better price.

I have EX200LC-2 that burnt the resistor on PVC and DP sensor. I replace both of them but it runs only for 40min and the engine stop also the water temp goes to red and it blows a lot of black smoke. Tried to fix the wiring by following the schematic but no luck.
So what else do I have to look at. The machine runs good at the start but once the temp level reach to red around 40mins. The engine dies. How could I know if someone destroke my pump?

Reviving an old thread here but I’m happy to report that all these years later she’s still going strong and to date there have been no new issues with the machine other than a broken fuel line that took 5 minutes to fix. Took this video a few months back...

Hi guys , Im not sure where to start, i recently purchased a 200-2 1991 with a major problems, ill start with the biggest one, When i start the engine it runs as normal, when i
use any hyd movement it goes very very slow.
Occasionally when i change the modes to e or s it will operate much faster and then stall the engine.
Any help would be greatly appreciated . Please explain where to find things as im new to this type of machine.
Note ( the wiring harness looks to be in good condition with no cuts or joiners or insulating tape ,it has also been changed to manuall trottle)
thanks

Hi ex 200-2 with the very common hydraulic problem.
i have fitted a hydraulic conversion kit to eliminate the elect controls and i have found , the engine runs very well freely and not choking with any movement for the first time.
Most of the hydraulics work ok apart from extending out the dipper arm (which is retracting the ram.) This only moves very slowly when i rev up the engine fully this dipper arm moves very slowly and with little to no power.
Im not sure where to start as this dipper arm was always slow and weak but its so bad now you couldnt load a lorry or do any work really.
Any help or advice would be great , thanks gerry davis
