A man took his wife to the doctors. After a short examination the doctor
said, "Your wife's mind has completely gone!"
To which the man replied, "I'm not surprised. She's been giving a piece
of it to me every day for the past 25 years!" |

Rotax Ducati ignition wiring diagram |
The
grey wire is your tachometer lead - it goes to one side of the
tach the other side goes to ground. The
heavy yellow wire and the heavy yellow with black strip are you
170 watt light coil, these connect to your regulator rectifier -
which then charges your battery. They can also be hooked up to SOME
strobe lights - CHECK before connecting to make sure your strobe
will work connect directly to the system!!! The
two remaining yellow wires are you ignition kill switch one for
each magneto. Connect them to one side of a switch and run the other
side to a ground.
Problem
I have a Rotax 582 with an after market electric starter. It seems
that about every two weeks my battery is low or dead. So I hook
it up to a charger overnight and it seems to take and hold a
charge. I suspect that the battery is not receiving a charge
from the engine. I hooked a voltmeter up to the battery leads
tonight. The battery had about 12.7 volts. Then I started the
engine and measured the voltage across the leads with the engine
running at about 3000 rpm. It measured 12.6 volts. Is this
adequate? I think it should
read more like 14+ volts. Any ideas?
Suggestion
Disconnect the leads from the lighting coil to the rect/reg check the
AC voltage with the engine at 5500 or so RPM voltage should be above
30 volts then reattach those leads and disconnect the leads from the
rect/reg to the charger read the DC voltage with engine at 5500 RPM
voltage should be around the 14 or so you anticipated.
You do have a problem, just where is the question with all wires
attached, you can read the similar points, engine running, and see
much lower numbers at the lighting coil outputs. the 'open circuit'
voltage from the lighting coil will be very high, perhaps even 50 V
AC, but connecting it to the rect/reg drops it quickly to 15
or so the DC output is the same as the voltages you measured at the
battery with the engine off, battery voltage should be 13 or so and
this will depend to a great degree on when it was charged and how
much, the small systems we use will not match a good commercial
charger for charging a battery, they will run them up to 15 or so, but
this high reading will be quickly reduced by either hitting the
starter briefly or turning on a device of some sort.
I suspect all the various parts but the usual problem is the regulator
rectifier. |
