LS 180B New Holland Skid Steer

[outlaw]

Hello guys, I am new to your Forum. I have added a Grid Heater kit to my machine and I am getting no power on the white wire that powers the solenoid to energize the wire to the heater. Do any of you have any idea where the wire gets it's power and also my dash indicator light does not light up. Any help would be appreciater. Thanks

The grid heater control system is designed so that the grid heater will not function at temperatures above 29 °F (-1.5 °C). The temperature measured is the engine coolant not the air.
The functioning of the grid heater is indicated by the cold start light on the instrument cluster​

when the key is turned on. The operator must pause between turning the key from the on position to the start position and wait for the cold start light to turn off. At temperatures

above 29 °F, the cold start light comes on for one second and then goes off indicating the grid heater is not going to function. At temperature below 29 °F, the cold start light will come on for between 10 and 15 seconds depending on coolant temperature. The grid heater is on for the​

same amount of time as the cold start light. Once the cold start light turns off, the unit is
ready to be started. As soon as the key is turned to start, the grid heater comes on again for up

to 15 seconds during cranking. The cold start light does not come on. After 15 seconds of cranking the grid heater will turn off. Once the unit is running, the grid heater will come on again for between one and two minutes, again depending on coolant temperature.​

If the cold start light does come on for at least 10 seconds, confirm that there is power at the grid heater. Place a voltmeter or test light on the power terminal of the grid heater during the time that the cold start light is on. There should be 12 volts at this terminal. If not, check the 300 amp fuse and the grid heater relay. Also, confirm that the grid heater supply cable is attached to the main power stud on the starter. There should be four cables attached to the starter. If everything checks out, replace the controller.

Confirm that the grid heater does not have an open circuit. With the key off, measure the resistance between the grid heater power terminal and ground. The resistance should be almost 0 ohms.​

If it is not, replace the grid heater.​

Thanks alot. This machine didn't come from the factory with a grid heater. I ordered a complete kit from New Holland. I have it installed and but I don't get any fire to the wire that plugs onto the heater solenoid. Do you know what gives the heater indicator light power? Is it powered from the switch and through the insturment panel or from the 300 amp fuse to the panel? Again I can wire it directly and it works fine. Thanks again for the reply. I have no idea which fust is the 300 amp. Is it one of the ones beside the heater solenoid behind the black plastic cover where the little black boxes are? Thanks, Darrel

The information I posted came out early in the production of the .B series loaders. There is no 300 A fuse. I took a look at an early L185 with the same engine and the cold start light did not come on when the key was turned to the on position. Is the ambient temperature below 29 degrees F? The way the system is set up the light and circuit may be doing what they are supposed to do.
You can change the engine configuration through the instrument panel. If you set it to an ISM engine the preheat light should come on even in the 60's F. This would give you an indication if the system is working. To change the configuration; The buttons described below are the light switch buttons, aux override and enable button. Hold them until setup is displayed.

​

Any button may be depressed and held for six seconds to enter the setup mode. The seat must be unoccupied and the ignition key off during this time, but the operator may sit in the seat after the setup mode is entered.

​

Selecting an Engine Preheat Profile:
[FONT=Helvetica,Helvetica]
[FONT=Helvetica,Helvetica]To select an engine preheat profile (item 1), press and release the work light push button one time. The word "ENGIN" will be displayed. Then, push and release the park brake push button. The engine type "NH" (for NH brand) or "ISM" will be displayed depending on the profile currently stored in the EIC. Push and release the road light push button to switch between the engine types. When the desired engine type is displayed, push and release the park brake push button to store the new selection. After visual verification, the word "SETUP" will again appear in the display.

​

To Exit the Setup Menu: [FONT=Helvetica,Helvetica][FONT=Helvetica,Helvetica](1) Leave the loader. After three seconds the EIC will automatically power down, (2) place the ignition key in either the ACC or the ON position or (3) push and release the auxiliary override button.[/FONT][/FONT]
