Hello, I'm having an issue on an 1872 I just bought... The pto switch was working fine, but now won't stay engaged. It will work if you hold the switch up, but when it goes into its detent it turns off...could the switch be bad or is there another source to this issue? I noticed the wire pigtail going to that relay looking thing on the left side is kind of melted but not too bad. Wonder if that would do it? Thanks in advanced
