    Hey all, first time poster. I am fixing a 3 phase charger at work for out electric go carts
    We just got these new chargers. I used to repair our modules on our old ones all the time. When we go these they were good for a few months. We had one burn some components but, I can't seem to find them. One is a wirewound resistor. On the top it says Royal 751 9w-s100 and the ohm symbol. But, I can't find it anywhere.

    Hi there
    welcome to the forums :)

    most likely a 9W 100 Ohm resistor

    you haven't said what country you are in ... fill it in in your profile ... it helps others that are trying to help you

    Mouser electronics have 100 Ohm 10W resistors

    that's just one version they have many others

    Be careful of the types of wirewound resistors you use to replace the burned resistors. The originals could be low inductance types because of the frequencies used in switching type P.S. There is a company called "Royal Ohm". Try
    Without a schematic, I can't offer much help! Ed.
