Well, another day, and another EC15 hiccup. Started looking at all the usual suspects, oil pressure switch, and water temperature thermistor as usual, customers hadn't been complaining as when the machine cuts out, they just restart it and its fine for the next good while. However it had cut out on me in the yard a couple of times so I thought I'd better investigate.
Suddenly I remembered about a little ECU mounted under the operators seat, I'd had trouble with these in the past.

This wee bugger gets an internal fault, or broken wires once they are inside the case, and theres not a lot you can do about it because all the components are resin bonded into the black plastic case
Its mounted on the back side of a panel that contains all the relays and main 50 amp fuses

The wires feeding it are none too clever and all twisted round each other ,... its a bit of a mess
... but if you mess with the wires while the engine is running, you are sure to get it to cut out, to be honest ... even before you strip anything out, just put your hand under the seat and give some wires a push, and if the machine shuts off, you know you are in the right place !

I soaked all the back with some cellulose thinners, a bit of a risky move in case any components get damaged, and gradually I started picking at the rubber

In reality its almost impossible to do without damaging something .. but before I got to this stage ... I made an interesting discovery
