Guys
I have been fighting the same type issue for a year now (my local Scags Dealer is technically challenged! :>) This is what I have come up with so far.
I believe that my issue, and maybe Georges is the "sensor" system and/or related components. What happens is when we would mow our 5 acres and the TurfTiger gets hot....if you shut the mower down it would most likely not restart. What I have ultimately found is that when this happens all I have to do is "short" the main B+ terminal to the small 1/4" terminal on the starter (better use a 12+ gauge solid wire because of current) and "bingo" the mower re-starts every time.
I have tested every switch on the handle bars, seat and brake. All good. When the unit is cold, it might or might not start up. Mow for a couple of hours, turn the mower off. Won't start!
Here's what it is....I BELIEVE.
Inside the control panel there is a electronic "module" and an rather large black mechanical relay. The Module is what detects and gives the go ahead to start if all the "conditions" are met i.e. handles out, PTO off, seat switch compressed and brake on. Then and ony then will the TT start. Now...even if all sensors are good and the module is good...still, the high current "starter" relay may be bad. That relay is what is activates when you turn the key to start, which then carrys the current to the starter. THERE's the most likely issue I think in that is mechanical.
Disclaimer: Hell I'm just and amatuer/end-user. I may be wrong about any and or all of the above. I'm convinced that if unit gets hot, wont start and yu can use the method above to
manually" start the mower....it's either one of the sensors, module or relay in console. Be careful when bypassing "the system". BIG safety issue.
Hope this helps.
