Deutz 4006 Starting Problem, Yellow Center warning light

[yamabrew]

Hello,
I need some help trying to find out what the various indicator lights are on my D4006 70's model tractor. I have been bush hogging in tall weeds (Dusty) and have blown the air filter out several times previously. The tractor would restart and run w/o problem after doing this. The last time, the center yellow indicator light came on and stay on continuously. Blowing out the filter did not help. I am replacing the filter. I plan on hosing off the engine body (Engine is air cooled) once I get it started and can get it back to the house.

Does anyone have any suggestions? Can someone tell me what the lights mean?

Thanks,
Scott

I think that is the battery indicator (meaning your alternator may not be charging). Check your battery voltage.

Deerseeker001 thanks for the welcome. Topher265 thanks for the advice. I will get it checked.
I have a feeling that I may be asking for more assistance with other issues!
