Charging Light

[normde2001]

I have no idea. I seem to remember that possibility being voiced earlier in the thread and was replying with that in mind.

I know when my problem first started, the light was very dim and turning on the headlights made it go out. Don't know how, don't know why. Later on, the situation progressed to the point that when the light came on, it came on bright and stayed that way, headlights or no headlights.

That's why he needs to know how much charge voltage he is dealing with. Needs to be about 13.5-15 DC volts.

OK, I finally got a volt meter. before I start it the meter reads 12.5

when I start it and idle at 1500rpms the meter reads 13.6

I waited until the charging light came on, it was very faint but now it seems like it is comming on sooner.

now what?

Kinda stretch, but make sure your alternator belt is good and tight. I have had them slip at higher RPMs

The battery is kind of low, even though the charging circuit seems to be working. Hard to say from a distance why the light is coming on. I would check/clean everything, and see if it will fully charge the battery, (about 12.75-13 volts).

Thanks, I will clean all the electrical connections I can and see if anything changes.

Same thing happened to me on my 18hp Yanmar and lately on my Yanmar/JD1070. I replace regulator but only fixed it for a while. Turns out it was a melted/burned spade lug in the plastic 4 terminal connector. Once this was fixed, problem went away.
