I have a JD 4100. It had some electrical problems last year amd I ended up replacing the voltage regulator with a 40amp alternator. A few weeks after, it started having trouble starting.
When I turn the key, it doesn't turn over for about 30 seconds and then shoots a lot of smoke.
I suspected a glow plug issue since after you start it once, it turns right over every time until it cools down again.
I traced the wires to the glow plugs and I tested them. They get battery power for 3 seconds and then they shut down. All 3 get power.
Does it mean that there is something wrong with the glow plugs? Do they all go bad at once?
What I don't understand is, when I turn the key to "on", the dash glow plug light lightbulb illuminates but it doesn't shut off until I move the key to start. Shouldn't it shut off after 3 seconds when the battery current going to the plugs shuts off?
