Hi
Chris and everybody.
I finally made my DVA meter. According to this diagram
http://forums.iboats.com/showthread.php?t=374544
Measured my cables, and obtained the following values.
The problem during the last two years, is that the engine been sick. Very sick.
No revs, no speed.
Earlier jobs
Changed the lower sealbox crankshaft, Gaskets changed on the carburetor, Fuelpump, etc.
etc..
Eventually discovered that the two coils did not give a spark when the engine speed increased over1500 rpm
Anyway this is what I got, sitting out in the rain.
Measurement between cable from box to the coil and earth.
Idling/High speed
Green/Black 254/260
Green/Red 253/260
Green/White 190/106
Green 190/103
Measurement of red and red/white from the stator
Plus on red/white
Idling/High speed
135/230
Minus on red/white
90/230
Measuring between blue and blue/white from the stator
Plus on blue/white
Idling/High speed
260/300
Minus on blue/white
300/270
DVA-measurement on the trigger wires was approx 8V
Then the question is, what does this tell me?
