MEP-804B cranks and starts sporadically

[Barn-1]

I have been running this MEP once every week or two since I got it in August '23. From time to time it won't crank. The fuel pump runs but it will not turn over. I can try it a few days later and it will start. I am new to Steel Soldiers so forgive me if I have missed a thread that covers this. It will crank with the manual switch but will not with S1. After it won't crank the low oil pressure light comes on. Any help will be appreciated. I have the manual, but this is my first MEP, so go easy on me.

The reason no one has written anything is because your thread is in the wrong place. I will move it.

Open up the control panel and take a picture of the S1 start switch. Lets see what version you have.

Here are pictures of S1. The oil pressure gauge may be bad also. When it does start it pegs out over 80 psi.

The S1 you have is what we call the Mark 2. It is a known problem child. This could very well be your problem. Look in the -24 TM for the test procedures for the switch.

Also make sure all the wires are tight on the switch.

Will do. The connections are good and tight, but I will test the switch this weekend. Thank You
