One of my customers / Friends picked up a S155FT sn: F024V02272M
There telling me the ECM is not sending voltage to the injectors or whatever it is that shoots fuel to the cylinders. I looked at the ECM that has 2 connectors with 80 pins on each connector.
that's a lot of pins and wires that go to something else that could have a fault, or a broken wire causing the problem. I work on a lot of electric trucks most of the time it's not the controller it's something else.
they did not say if it had any codes.
I'm thinking it has a busted wire or bad relay.
The ECM is pricy. I haven't found anyone that can test this thing or anyone that sells reman?
Briggs gave me a price on new one.
Briggs got back and said the do test them need to call service dept. will start there.
any other tips would help
