Resistance readings for Ducati Gas Gas TXT pro 2007 stator

9 posts in this topic

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.

This is too old for your model but....can't find the right one.

The wiring seems similar, not sure why its on a modern txt, looks like I'll have to take it to a specialist. Electrics is my nightmare come true. At least my trusty Montesa 315 keeps going stong..  Thanks anyway

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

Yes, the bike ran fine, no problems. Thanks for the info. Will post the solution when problem is found.

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.

Update, the CDI and voltage regulator seem to be the problem, considering how much those parts cost I think I'm going to convert to a kokusan system. Now I just have to wait and see what comes up second hand.
