I finally got the pickups from Electrix and installed them, problem is that it still will not start. I'm going through everything to make sure it all works but how do you test the pickups, thanks.

just check the workshop manual.
It says there (p. M.14) to measure the resistance which should be 220 ohms +/- 5%.

ok, G so I know what they should be but how do I do it?

as mentioned in the Haynes manual (ignition section) that you also find in the downloads you disconnect the two pin connector from one ignition box. Then you set your ohm-/multimeter to ohms x100 scale and measure between the two cables red and white. Write down the value, reconnect and then do the same with the other connection on the second ignition module (by memory it should have a black and yellow wire).
Values should be the same on both pick ups.

Interesting btw that the Haynes manual for Supersport/Monster says they should have 95-105 ohms which is quite a difference to what the Paso manual says which makes me wonder as all shops sell the pick ups to fit all carbed belt driven Ducs. Was the resistance reduced to gain a stronger signal, anyone know ?

pickups can be tricky, but they are very simple devices the either work or don't.

the distance from the flywheel is VERY important, you will need to checvk this carefully; sometimes 1/10 mm is more than enought to cause problems.

another thing is the way they are connected, I never tried, but I was told that if you swap the wires (polarity inversion) the pickup will not send the right signal to the ECO/MODULE.

Another issue is that the you need to be carefule in connecting the right pickup to the right module, by inverting them its a SURE non starter.


My suggestion is to remove one plug, tghe fuel tank and see if you can drain the fuel from the carbs.

then with ONE PLUG ONLY start checking if you have spark and see if you can start it by squeesing some fuel directly into the the carb mouth (only the cilinder with the spark plug)

this system will allow you to focus on ONE pckup and ONE set of casbles at the time and by using a small syringe of petrol you can also be sure you are not flooding the engine.

if the cooections are correct the engine should start straight away on one cilinder and run for 3-5 seconds.

once one Cilinder is done you do the same with the other.

It is a little bit tedious, but this was the way I sorted mine and it took only 30 minutes in the end...

NOTE: with an IGNITECH ECU the software will tell if the pickup are working and allows to invert polarity and swap pickups without touching the engine.

You can tell by the color of the wire, also on mine one set was longer than the other.

Also heat / oil damage to the wires requires new silicone heat resistant wiring be fitted to avoid shorting .If this has been done previously ,odds are that the wires are all the same colour ,very easy to mix them up . J.

Why not just hook up your timing light to one plug lead, point it at the timing window and see if the correct timing marks show up when it fires, just swap the spark plug leads over from one pot to the other if it aint right

So, for the sake of argument lets say you're not an Engineer nor do you have a timing light that you are just a rider forced to be a mechanic. How do resolve the issue?

i used a snap on vantage to test my pick up coil it showed ohms and a pattern.
strangle enough my 88 paso only uses one pickup coil . i am haveing some trouble
with the ignition dropping a cylender after it totaly warms up the front/horizontal
cylender looses spark.
i found a source for new marelli digiplex boxes.i ordered a couple & a spare coil

Most frequently dropped cylinders are loose or poor connections,don't forget the spark plug wires, very common and can be hard to trace when intermintent. Vacuum leaks at the carbs can also cause dropped cylinders sometimes using the choke can help pin it down if it improves with the choke on. Marrelli Ignitions don't generally go bad on their own, poor grounds will fry them quickly so make sure you track down the cause before you put it a replacement

i did go through the whole bike servicing all grounds and connections i am going to go for an extended test ride today.the worst two connections were where the battery & engine cable meet on the frame & out front at the starter.
this seems to of helped correct charging voltage rates & starter speed.
i will post results.
