Hello, I have a New Holland L230 and glow plugs won't come on. I've asked for help on the NH forum without luck. This is a 2015, thinking they might be similar to case. (CNH) and looking for help. Been fooling with this for awhile. 45 degrees this morning, it started but ran rough, meter piggy backed on glow plug wire, no voltage , they did not come on. New module, wires ohm out, plugs within spec, no codes. 12v supply and ground check out. Have service manual but it only give trouble shooting sequence for codes. Any help appreciated. Thanks
