my g26 fired up for about 2 seconds. now i have no spark. how do i know if its the magneto or the coil? what kind of voltage should the magneto be throwin to the coil through the red wire?

chief08087

everything ohms out to spec according to the service maual

BB Modss

Place your red (+) test lead to the red wire on the source coil (red) with the coil wire off, place ground to a well grounded location and give the motor a big pull with no spark plug, should see spikes (dc voltage) of 12+ volts, if your DMM isn't fast enough then put a small 12v light bulb to the coil and then to ground, when you pull it there should be a flicker of light, if all is well there move onto the ignition coil. All else fails shoot me a pm ill get you sorted out.

damn im only gettin like 2 volts. earlier i was gettin like 5 or so. damn thing only has about a half hour run time on it. is this what i have to look forward to everytime the boat gets dunked

The brass tabs on both coils need a good ground connection to case, make sure there is no corrosion between the brass tabs and the case, if using a coil relocator make sure the tab is contacting bare aluminum as anodize is nonconductive.

nah theres no corrosion. that was the first thing i checked. source coil is beat. this happen to u guys after flippin a boat and everything gettin wet? this is my first boat. i dont think i can afford this hobby lol. $55 for a coil

Doesn't sound typical for a source coil to quit by getting wet.
A dunking usually creates other damage. Bent/twisted cranks are common from dunking, check the air gap between coil and flywheel.

I have been running Zenoahs for over 5 years and only had 2 grey coils go out in that time and never lost a red (knocking on wood!)

well i guess im unlucky

martno1fan

Wow you are unlucky thats really bad luck .

chief08087

My Feedback: (2)

That's a unlucky boat, I would take it to ebay then buy a good one.

chief08087

well. i put the ohm meter back on it and just watched it. it kept goin from open to the correct ohms!!! pulled the plug boot off and the piece of metal that is stuck in the wire wasnt making good contact so i pulled it out and stuck it in again. spark problem solved. can anybody give me some good carb settings for this motor. its a 260 in a shockwave 55 all stock

Believe It

1-1/2 and 1-1/2 will get ya goin. Do you know how to read the plug?
