Brad good to hear,

i think i replaced mine early on in ownership but cant recall.

Did you put thermal paste on the back of it?

FWIW if you convert it to wasted spark you bypass the factory power stage module 😛

    nugget_940 I didn't put any new thermal paste on the replacement one but I'll do that this afternoon. Thanks for the reminder.

    I've considered going to wasted spark on my 940s. Just haven't got around to it yet.

      Glad you had a quick resolution time.

      The thermal paste going off is what kills them, they lose the ability to transfer the heat out of the module into the heat sink and overheat. Then something in them fails. Re-applying fresh paste every few years is a good preventative measure.

        I imagine wiring and connections need attention too?

            Only on the radio suppression relay

            The connectors tend to come out of the relay often on those

              Looks like the 740 is fixed. It's been driven a few times since replacing the power stage and there have been no breakdowns. Happy Days.

              I also replaced the thermal paste on the back for good measure. Don't really need another breakdown.

              Is it possible to mark this as solved?

              @Brad yup, I highlighted the solution already, you should see a ✅ and the answer in green at the top of the thread.
