Re: Ignition Coil Voltage

you mean from the ignition coil , 30 volts should be okay ? Well , that gives me some kind of an idea now. I have to determine how to diagnose the boxes and the pickups . I just checked it again and sure enough it is about 25-30 volts AC coming directly to the right hand box when I disconnect the gr...

Re: Ignition Coil Voltage

If anyone has a cranking voltage of the green wire to ground in AC volts please let me know. I don't want to pull the whole ignition coil off and rebuild it if 30 volts AC to ground on the green wire is sufficient to power up the red pick ups and the red dot boxes . It would be nice just to know if ...

Re: Ignition Coil Voltage

The pickups measure around 610 ohms one way only on diode check , so they are quite uniform . . This is quite stumping , because not anything that obviously bad . ```````````````````````````````````

Re: Ignition Coil Voltage

Does that 30 volts AC make any since ? Is this about right or should I worry about the input voltage ? I don't want to waste time with anything that I should not. I imagine the faster that the rotor goes on that ignition coil the more voltage that it will produce but just cranking normally is what I...

Re: Ignition Coil Voltage

Now , just wondering if the cranking voltage of that green wire sounds about right . It cranks pretty slow with the battery I have but does 30 volts AC without running the engine sound correct ? Also , is there anyway to check the red pickups with a meter ? Thanks

Re: Ignition Coil Voltage

Well, I have an update to post on this , I did finally get the pick up off from the camshaft . I checked it out and it measures about 600 ohms on diode check just one way only on both coils. I did not realize that there was a diode in this pick up. I don't know if it is good or not. Now the green wi...

Re: Ignition Coil Voltage

I am checking the pick up coils and find that they are about 107K ohms to 111K ohms . I don't know if this is correct or not but seems a bit high. also I tried to take the pick up coils off from the camshaft by taking the locknut and the allan screws off but it's stuck and I did not want to damage i...

Re: Ignition Coil Voltage

I have a feeling that the switch is okay but the configuration of the wires to it may be wrong but cannot prove it until I get some kind of color to the corresponding number on the back of the switch . The switch has numbers for each terminal but the schematic has not numbers to match up , just a ha...

Re: Ignition Coil Voltage

Since I posted I did notice something else in the circuit . There is a terminal strip with a diode, separated from everything, the cathode goes to the switch on the green wire and the anode goes to the transducer. This diode appears to be separating the transducer from the switch. When the key is in...

Re: Ignition Coil Voltage

I suspected that the wires may possibly be in the wrong config on the switch but have not way of identifying which color goes to the proper number on the switch. Would anyone possibly have the configuration of which color goes to which number ? I have the schematic but it doesn't really have an accu...

Ignition Coil Voltage

I am new to the forum and to the Moto Morini 500cc 1979 or earlier possibly that I just accumulated . I do believe that it is the red pickups with the regular black transducers. It does have electric start. The problem is that it has no fire whatsoever. I have checked everything but not getting any ...
