Just purchased my Summit tractor and flashers and turn signals do not work

...most electrical parts are one click away from total failure, even when new on the shelf.

Most electronics, short of electrolytic and tantalum capacitors, are designed to 1 million hour mean-time to failure (MTTF). That's just over 114 years, which of course is a mean (average), which is where things like standard deviation (consistency) become important.

What you're usually seing is not "electrical part" failure, but usually failure of the mechanical components. It's always the electromechanical components that fail in any system, not the electronics.

Think of your 30 year old home stereo, and what broke? The electronics, or the tape deck? The electronics, or the CD transport mechanism? The electronics, or the belt on the turntable?

In your car, what bit of "electronics" always breaks first? Mechanical relays and mechanical blinkers, or mechanical window switches.

Electronics rarely fail, unless over-volted or struck by lightening. It's always the mechanical or electromechanical components that go, first.

Im not sure its just the flasher unit. Usually turn and hazard flashers are 2 separate units. My tractor has 2 flasher units, so do all my trucks. I cant see 2 flashers controls failing at same time

@Triple 5423, debug of these systems is pretty simple. What tools do you have available? Test light? Multimeter?

Generally speaking, you put the tractor in a state where the blinker should be working, and then chase the circuit from one end to the other. So, key in run position, blinker switched on, check at bulb socket with your test light. If no power, move up to the fuse panel and check voltage coming into the blinker relay. If good, try jumpering the blinker relay with a scrap of wire or paperclip. Does the blinker light? If no good, move upstream to the fuse, and check for voltage on both sides of that.

If you find voltage all along the way, and it's still not lighting, then it's time to chase your ground path. Run a ground wire from battery negative right to negative side of blinker bulb socket housing. If blinker starts working, move that incrementally upstream until you find the bad connection.

Summit sells thru box stores that do not do service. Service is done through a separate group of companies. Check the website to see if one is closer.
