I have been doing some research trying to find testing information and how they work. Maybe my search FU isn't good as I really can't find anything. So I downloaded the patents and took a look.
My focus will be on the EESS , 3S and the TSU.
The issues I have is the wait light flashes 7 times... This is my first clue. There must be some type of micro controller in the unit. Sure as it rains in Washington there is. Looking at the patents I see a PIC micro controller. So I am 97.2% sure this is a diagnostic code. But what does it mean? I am sure there are others.
Someone suggested to test all glow plugs. This is easy enough with a test light. However I would like to know how the box knows the glow plugs are bad. If they are all bad I can see that and there would be an open circuit. But say there are 4 bad and 4 good and the golw plugs are in parallel. Sine the glow plus resistance is like 2Ω each and the parallel circuit thing would more or less look like to have continuity.
I have been reading that some people have had issues where the wait light flashes ones. looking thought the documents that seems to be a lamp test. This makes scene.
Looking for input and let see if we can figure these things out. Maybe just maybe was can fix these and save $$$. Sure I can load the parts cannon up and fire away wads of money. But what fun is that?
