This is actually 2 questions, 1 in depth. I had a bad VRO pump that I just replaced 2 weeks ago. Tried to take the boat out the following weekend, no start. Turns out, I'm only getting spark on #3 and #4 cylinders. I have a service manual, and went through the trouble shooting guide, step by step as directed.
#1 On the Charge coil output test, the meter is supposed to read over 130vdc. I am getting over 130vdc, but it is pulsing. As I'm cranking, is jumping from 0-140 (back and forth) very quickly. Is that a normal reading? The book doesn't say any thing about steady 130vdc.
#2. Performed a sensor coil test. No grounds found in testing. (which is good). I'm not getting my .2vdc or higher on my sensor coil signals. The wiring is clean and free of corrosion.
So I moved onto the resistance check of the sensor coil. Now it is saying to use 2 different brands of Ohm meters. (both analog). I'm using a fluke digital. Its saying to check from the system common, to each signal wire. Its supposed to be on one meter 360ohms or the other 970ohms. My fluke is telling me all the signal wires are open (Infinite resistance). Also when checking starboard to port signal commons in series with each other, it's supposed to be 230ohms (not specific on a ohm meter) . I'm getting 690ohms. Can I attribute this to not using their specific analog meter? Or should I replace my Sensor coil?
