AHEM  , anyway, new transistor is fitted and the new symptoms are..... motor runs at full speed in all throttle positions though reverses as it should

any more clues fellas?

[Sandy Calder]

BUZ off.....this is a hijack.

onthe other hand do check the outputs of the ZN409 because the relay pin can be ok and the ones that drive pwm are gone.
Once that is ok go back to the FET gate and trace back.
Also test for a FET case short to -ve.

I have never "bashed" Electronize products on this forum - or any other forum. I had one a long time ago (pre-ACTion) and it never gave me any trouble at all. You can see at least one example of them at any model boat club on any given Sunday.

There's really no need to 5lag-off other manufacturers' units - especially one with such a fine and long-standing reputation as Electronize. It's not clever and it's not productive - modellers are not complete idiots, even if they don't understand the stuff you write.

Andy - if you need a new ZN409 chip then I still have a few in stock.

Right, this topic needs a clean up!
I'll lock it for now, get the Hoover out and unlock it later.
