Just checked under the step and everything is mint clean. The motor is getting a solid charge voltage. However, the push button is getting 4.73 volts, exactly what the EM50 is sending out to it. Gonna be that board again for sure.

Might be right if it's direct the the 5V computer control.
Yes, upon reading something somewhere else i think it is somwhere between 4.5-5.0 that is the correct voltage, that is what I was getting also on the limit feed.
I then wondered whether the whole system was confused and pulled the two main battery fuses from the EC325 and disconnected the EM50. Now I've plugged it all back in I have absolutely zero voltage on anything step related on that harness connector, not even the 2 x 12v motor feeds.

Must be. Doing this sort of testing a headlamp bulb makes a good fuse, max current 5A or so.

We're onto Sargent now. The thing is it always seems like Jaws problem, intermittent and every 20minutes it does something new. Here is my explanation of yesterday. Check the states of your battery compartment temp sensors too as ours had totally disintegrated and i suspect may be part to blame for a strange death of 2 x 110s
Yesterday I took the cover from the step, all connections including the limit switch look clean.
We were getting 13.1 volts at conn9 and 10 on the harness connector, 4.73 on conn13 for the pushbutton and similar for the limit switch.
With us having problems and putting in new batteries I thought I would reset everything, so I pulled the 2x 20amp battery fuses on the EC325, didconnected vehicle neg and em50 unit then plugged everything back in.
Now we have zero voltage at any of the above mentioned connectors. Is it worth me checking anything else or is this scenario an EM50 problem?
