Resistance readings for Ducati Gas Gas TXT pro 2007 stator

Recommended Posts

I have a 2007 TXT Pro and have a no spark issue. I have checked the usual earths, kill switches, spark plug new, cap new, still no luck. I have downloaded the Ducati ele diagram but no values on it. The Kokusan diagram has the values but not sure its the same for Ducati . As Im in Slovakia I cant take it to a specialist in UK until October.

Does anyone know the resistance and voltage values to check the stator and trigger coil. Then if its not the stator has to be cdi or volt regulator.

That stator looks as if it has been hand rewound. Has the bike run since it has been fitted?

The source coil for the HT is usually wound with very fine wire (about 0.2mm) and has a resistance of about 50 to 90 ohms.

The trigger coil resistance will be in the range 800 to 1250 ohms

Resistance is not a good guide to serviceability. Far better to spin the flywheel with a drill. The source coil should give over 20V and the trigger coil 1.5 V, possibly up to 4.5 V.

If the "trigger coil" gives different resistance values when the meter connections are swapped round, it is a hall effect sensor and you really need an oscilloscope to check it

It is worth concentrating your investigation on the pick-up/trigger coil at first as a few people found it to be the cause of no sparkl on that year of GasGas pro that I Know of.

Too true.

If you look at your stator coil with the extra resin bulges there are dark areas in them, this can indicate burning / overheating.
