Hi all - longtime reader, first time poster.
I've got an about 4-5 year old hayward tigershark that I inherited from the previous owners of the current house. When I started using it over this past summer, I had to go ahead and replace several parts to get it up and running (one side, both rubber treads, several bearing guide rollers, the impeller), but at that point the tigershark was working just fine. Recently, when I turn it on it does it's initial 3-4 second power-up cycle, then stops, then runs again for another 3-4 seconds then stops completely. I'm trying to figure out what the issue could be now - I've disassembled the cleaner again and there's no debris or other structural issues I can find. According to the troubleshooting manual it could either be the motor or a power issue (I'm assuming a power issue could be the power supply/controller box or the floating power cord). Any advice/insight on how to diagnose the exact issue? I don't have a multimeter or a hayward error code scanner, either.
