T190 Dead

[Spits]

2004 T190 was working fine, then hydraulic oil light flashing, oil level is fine. Changed filter 15 hrs ago. Other day was using it and it shut off. Started again was using maybe 10 minutes and shut down again. Now no power to switch or display??

First you must verify you have power coming into the cab. Check the 100 amp fuse which is directly above the battery in the engine compartment. Follow the power cable that goes strait up from the battery, not the cable going to the starter. Then start swapping relays with relays properly work, like the head and tail lights.

Thx for the reply. I've checked the 100 amp fuse, and put a multimeter on all the relays and fuses, all are good. I checked power to the switch and there's power there and multimeter the switch and it's fine. Not sure what else it can be. Turn key on and no displays of any kind. I did have a flashing hydraulic light prior to this shutdown.

you have power to display?

No, if I turn the switch on none of the displays light up. When the unit last ran however, the hydraulic light was steady flashing. Would this have caused the unit to shutdown?

The hydraulic light could trigger a shutdown. However, it wouldn't cause the display to keep from illuminating. I'm guessing you have a short somewhere that caused the hydraulic light and now the display issue.

have you measured the voltage to the display? look on the schematic to trace the power circuit, as mentioned sounds like a short or broken wire

Have you load tested the battery? Shorted out under load? May be a combo of things the sensor for the hyd system find that and jump around that sensor. Or test the sensor. May dump the system but not the display.
Another fuse for that display or all checked?
That leave low oil both eng and hyd. As a possibility but doubt that. Some said a short maybe behind the display. Start this the basics Filters, Change the low oil engine sensor. Maybe just needs to be seeing oil. This is all controled by these safety switches some times but each machine does things a bit different. Just food for thought. Good luck! Post any finds so we all learn from it.

I just saw a post on another unit and he mentioned a seat switch that when sat on lights up the instrament panel. Any chance of that?

I pulled the covers off on the switch and middle cover and used a test light and there's power to the terminal blocks and the key switch. However when I turn the key on, display doesn't light up.

so you have power to the display? can you test the power out the switch when you turn the key?

This has power to the display he said but the display doesn't light up he said also. I came across one guy that said his display would not light up until the operator was in the seat and the safety bars pulled in position. So I wonder, is this possible that the safety bar will not allow the unit to start or is the safety switch for this unit not working? All the normal test indicate that there is power to the display but the unit does not start. Maybe ? Or is it far fetched of an idea? Just putting that out there. Food for thought.

you have power to display?

Yes, I put a test light to the wire blocks on the display and there is power there, as well as to the wire block on the key switch but no display when I turn the key on. Put a multimeter on the key switch and turn key to on and start position and both show as OK.

you checked if the ground was good? to the display?

Would the only ground be at the battery?

there may be several but check ground to display

Anytime you are working with circuit boards you want to leave your test light in the attic of your home with all the other antiques unless you're looking to buy new circuit boards, get and use a digital volt ohm meter.

Is there any chance that there is a safety switch built into the seat or the safety bar to prevent start up or activate the dash lights. I saw that somewhere and I have not seen a reply so I will drop that if it's been covered.

Purchased a new right hand controller/keyswitch installed it and the displays light up instantly. Worked the machine for 1.5 hrs and parked it. Next morning started the unit and it would run and then stop. Started again, moved the steering levers, unit would stop. Did this again and unit stopped, now no display again to either switch display or other display.
