Rewiring RGS ignition pickups

Took my RGS to Wolfgang for a tune and he suggested I replace the lead wires on the pickups and warned me not to reverse the negatives and positives.



So each pickup has a pair of wires (see bottom pickup) the left hand wire has a black tracer.... is this the - or the +

Next issue is how do I get into the plastic to resolder new wires on? Wolfgang tells me these are no longer available and the wires fail which was why my bike ran rough, unfortunately a friend grabbed this from him for me to fix and he didn't pay attention. Wolfgang must be out of town for the weekend and I'd like to fix this tomorrow.
 
Replaced the pick-up wires on the standard ignition on my RGS years ago, before I saw the light and swapped the whole lot for a DMC II setup.
The insulation on my pick-up wires was completly rotten, had to cut the cables leaving enough of a tail on each pickup wire to solder a new length on. Make sure the wires are properly cleaned and tinned before joining the new length on. You can use the same process at the other end at the connector. Good idea to put an appropriate length of heat-shrink over the wires before soldering.
If you aren't comfortable with your soldering abilities, suggest you get somebody who is. Not much wire to play with on those pick-ups.

I'd like to know more about crossing the wiring...is it a matter of being out of phase or is there more electrickery involved. One of the reasons I ask is that the Ignitech box can detect if the pulses are positive or negative and can compensate...I think...
 
If you swap polarity of the pick-ups they function differently. 

In stock configuration, the pulse is generated when the trigger advances towards the pick-up.  When polarity is reversed, the impulse will occur when the trigger has passed the pick-up.  Easy to check with a slim screwdriver.  Either the spark occurs when the screwdriver hits the pick-up (stock), or when you pull it off the magnets (reversed).

Don't think even the Ignitech can cope if they're not all the same way 'round.

There's a reason for everything... :D

Thanks! excellent info and a simple test!
Has anyone ever found an alternate pick up? With the original pickups seeming to be scarce I would have thought that a alternate may be available....?
Is there more to the electrical  than finding a comparable resistance? After that its about what can fit...
 
Soldering may fail due the vibration, use insulators instead. And maybe silicone cable instead of separate wires...

Mine weren't in nearly as bad a condition as yours appear to be, but because of some checking and cracking I replaced mine, too.  Pic below shows where I cut the old off and spliced on the new.  Soldered and heat shrinked 'em.  They won't come apart.  There's not a lot of room in there, so you have to be strategic about where you cut and splice.
