These coils can be easily damaged when removing the protective rubberized coating from the underside of the TurboExpress / PC Engine GT.
If L501 or L502 are missing or damaged, these replacements are a direct fit!
Product Note: Coils sold here before December 2017 may present shortened battery life. These coils had higher than expected resistance and falsely trip the low battery circuits but function without issue on DC. If you purchased these from us, please contact us with your order number for complimentary replacements if needed.
