ok great but your op your asking if there is a way to check it but now you say you have all this experience and its easy. but i dont break up parts from a kit and if i need to go to pick up the part from a supply house then the customer is paying for that time. i wasnt suggesting for you to buy a whole kit. if i was repairing my own, i would replace just the part. i love how hvac people think they are electricians. i am not saying you dont have the knowedge, its just my experience from being in the trades.Magnetic ballast are so easy to repair so why buy the hole kit if you know its only a 20buck part? I do alot of electic work and have all the meters to ckeck the parts.I even have a digital Capacitor tester.I dont know the brand name,but a Transformer and Capacitor all work the same on everyone,as does the ignighter as long as it the proper voltage.It only takes 15minutes to check the Ballast So its not very time consuming.
