Hey everyone. First time poster. Just joined today. New to the riding mower scene. I just recently purchased a Scott's riding mower, 16hp and 42" cut, used. I know under the seat it says model 1642H but I think they are the same as S1642. I don't know. Lol. I feel like I got a good deal on it. It is in good condition, came with an extra oil filer, 4 air filters, a bagger, the cover for mulching. One thing I noticed is that the headlights do not turn on. I know I'm not going to be mowing at night, but I like when everything works as its supposed to. I tested the bulbs using a multimeter(new to using one of these also) So I held one of the probes to the side of the bulb and the other to the end. It went from displaying 1 to displaying 000. If I watched the youtube video correctly, that means it was working and good. I then touched the connections on the bulb socket. It didn't read anything until I turned the key off. Which would cause the numbers to rise quick then drop, which to means, it was getting some sort of power for the multimeter to read it. I don't know if I am using any of this equipment correctly or not. So if anyone has any ideas on what to test or what to check, let me know. I will try and give you as much info as possible. Thank you.
