Posted by member Cora Jane Heal on Thursday 4 November 2021

We have had a very strange issue over the last 2 yrs where randomly on either engine the forward and reverse polarity would switch on start up, turning on and off sometimes sorted but it stopped us going out and having fun on many occasions
Finally after lots of engineers said that it was impossible and it couldn't happen, we managed to replicate the fault when Martin a great senior tech from PME was onboard, after a bit of digging he found out from the manufacturer there is a little black box with a software update to stop this happening took about a week to arrive, he plugged it in the lights went green in a few seconds and haven't had it happen since
Just in case anyone is thinking they are going mad when it happens to yours
