African Dust,, if you are looking for a project DR I might have one for you if the price is right

Hey Sc, wish I had the time but I learnt my lesson once before... I need a clean bike as I barely have enough time to ride..let alone project a bike. thanks for offer though.
chopper pilot (until Kykdaar becames a professor) is the Guru in Dr's maybe he is Keen ?

Whats this i hear about a project DR ???? Nee Chopper jy kan nie nog een koop nie!  :peepwall:
and she said " What are you doin today ? ".
and I said " Nothing ".
and she said " But you did that yesterday ".

I think I'm going to sell all my toys except my one DR and buy a 990 and a really bling Twat suit

test for voltage pulses to the coil whilst swinging the motor.if you dont get unplug the pick up from the crank and measure resistance should pulse to couple of ohms then high as you swing the motor

Dont need regulator to start the bike as long as battery is charged

First up was the CDI - here I did a large sample of the possible tests and on every occasion found the readings the same as, or within the range specified. My conclusion is that the CDI is fine.

Next up was the ignition coil - first up the primary ignition coil resistance measured at the wires leading to the ignition coil. Found a value of 0.01.

Then I measured the resistance over the secondary windings (spark plug cap to spark plug cap) and found a very high reading of 69 Ohm  compared to the 23-25 Ohm spec.

I think that I found my second culprit.
23K to 25K if your plug caps are not standard they may have fitted non resistive type.2x 10k caps plus your 69 ohms hmmm strange how you got 69  :o
pull caps off and measure each one

Unplugged the coil and tested for voltage pulses to the plug - only had enough in the battery for a few swings, but I got pulses between 12 and 15 volts. Will confirm when the battery has a better charge and will then try it with the rectifier both connected and unconnected.

I will double-check by performing the second test as well. Are you referring to the pick up wires which goes from the generator into the CDI?

Suzuki spec as per manual for resistance in secondary winding measured from sparkplug to sparkplug cap is 23-25 K Ohm.

This evening I played around with the plug caps in more detail -

The plug caps each contain a resistor and if you measure accross a single plug cap the reading is 10K Ohms. If you remove both plug caps and just resistance through the wires you get 004 K Ohm. If you put everything together and measure accross the spark plug caps you get 24 K Ohm.

Found out that my one spark plug gives no reading when measuring on its own and that a reading of 1 (open circuit?) Is now given when you try and measure accross the caps.

12v pulse is fine.recon plug cap is the problem :thumleft:

No need to check the pick up as you are getting pulses to primary.easy once you know what to check

Would it not then still have sparked on the second good plug? I checked and it did not.

I checked the pick up in any event. K Ohm at rest is 204 which is in spec. Could only crank it a few times, but saw readings as high as 215 and as low as 63.

Take the cap off and hold it close to the top of spark plug

Hahaha ja right ;D

Thing is i put my own fingers there and nothing.

Only thing I can still do is put another plug in it and give it a try. Not very hopeful though. There is something mysterious going on here.

Make sure the metal pole of the coil is earthed properly

Remove a plug and earth it to engine then Unplug the primary wire and run a piece from the battery and pulse the coil like you would with morse code.if still see no spark get another coil
