Not many folks do not have a meter capable of resolving the almost dead short of the primary on this coil. This in mind, beware when running two bilge pumps.a battery going bad (high internal resistance) and two bilge pumps running for a extending time is just enough to cook a lighting coil.Ĥ. This coil is rated to generate up to about 2amps of charging current. This coil puts out close to 20+ volts AC, to be recitified to DC and regulated at 13.5 or so to recharge the battery. Anyway, you should see 6 to 10 volts or so here, again AC. This coil's name is a throw back from the old enduro bike days, when the manufacturer would add a coil to the stator to operate head, brake and turn signal lights.without a battery, and later with. If you are having problems with the battery not recharging, then dis- connect the two green wires and read the cranking voltage produced by the "lighting" coil.
(ps, an analog meter is best for this test)ģ. You should get a pulsating 4 to 5 volts AC. Dis- connect the white / red trace wire and connect the meter leads to this wire and the ground wire. It's job is to tell the cdi when to fire the energy stored in the capacitor. You should have 30 to 50 volts AC depending on how good a battery and starter you have.Ģ. This coil can generate in excess of 500 volts!!ĭis- connect the brown / white trace wire and ground wire and connect the meter leads to these wires, and while cranking the engine, observe the reading. Don't get confused with the term "charge" coil.this is what Yamaha calls it, as it "charges" the cdi capacitor. check the AC output of the "charge" coil.
YAMAHA GP760 SPECS SERIES
This applies for most any ignition problem with the 701 61X or 62T series ignition components.ġ. I hope this helps everyone make a quick diagnosis 8) Since so many have electrical ignition questions, I thought it would be handy to keep this "quick test" guide at the top. The information below was specifically written about 61X and 62T motors, but applies to any Yamaha waverunner with a 650/701/760 motor since they all have basically the same components. This was not written by me - but there seems to be enough people here that have electrical issues that it may provide useful to post it.
