Hi everyone,
I have been impressed with the knowledge contained in these forums.
I need some help with a 1991 70 HP Force.
It has been getting harder and harder to start.
Took it out to the lake and got it running and then stopped the engine for a bit.
Would not start. Has fuel and the carb has been removed and cleaned.
I have did a spark test and if I set my spark tester really close I can see a weak spark.
Also if I ground the removed spark plug i can see a tiny blue spark.
Have a good battery connection battery is putting out about 12.7 - 13 volts.
When attempting to start the motor is definitely turning the required 250 RPM.
I took all of the stator and trigger wires loose and run an ohms test.
Here is what I have so far.
I do not have a DVA adapter at the moment.
I have Control Box has P/N 332 7778A10 on it.
The stator looks like the original black one.
Couldnt fine the P/N on it.
Here are the resistance readings from the stator and trigger wires.
Red Stator to Engine Gnd - 138 ohms
Blue Stator to Engine Gnd - 2,234 ohms
Yellow to Engine Gnd - 9m ohms
Yellow to Engine Gnd - 9m ohms
Trigger wires
Violet to Engine Gnd - 15,500 ohms
White to Engine Gnd - 15,500 ohms
Brown to Engine Gnd - 15,500 ohms
Violet to White/Black - 1,200 ohms
White to White/Black - 1,200 ohms
Brown to White/Black - 1,200 ohms
I haven't figured out how to test the coils yet.
Also I have tried the starting with the yellows unhooked from the rectifier.
And also with the stop circuit disconnected (black/yellow).
No change
Can anyone tell me if any of those numbers look amiss?
Thanks
Lynn Nightingale
