Details, bought a used machine, running on single phase power via a used (from a different vendor) 20 hp rotary phase converter.
Machine was as is, supposed to work, saw it under power at the shop.
Day 1 - wired everything up, turned machine on and "played" with it for 6 to 8 hours.
Day 2 - system 930 alarm, several times, 6th or 7th try it turned on, "played" with it for 9 or 10 hours, got dnc working.
Day 3, system 930 alarm, appears the machine will start when it's warmer out. I'm in socal, it's cold for us but not so much as cold as it could be. Once machine powers up, appears to function fine.
Day 4 - have a local service guy spend 2 hours, swapped the power supply, same thing, recommended a new main board and or bubble memory card. $1600 to $2200 but not certain that is the problem.......... (it was raining that day)
Day 8 (today) - warm out, powered up with 930 alarm, after 3 tries, machine started fine.... let it idle and cycled power 3 times in an hour. seemed to work as it should each time.
Tonight - Got home @ 11pm, it's cold, machine 930 alarm 10 times, never started up......... now looking for troubling shooting ideas or a repair guy in so cal that can fix it based on facts.
