jawa 207 need helo. STILL no spark

Colton Opinker /

Im on the verge of giving up and cutting my losses. i cant get spark and i remade the thrysistor. i just ordered a new coil. Im getting weak or no spark. this is over the top frustrating and i really need help. no\real weak spark is the problem. i made the thrysistor and put it on. timing? i have no clues left. other than the coils not giving me a reading on the ohm meter when i thouch to each solder point.

there is an ignition coil, lighting coil and sensing coil. for spark you need to test the sensing coil and the ignition coil. Both should have continuity. If one does not repair or replace. (rewind or find the bad solder contact to fine wire break). It is common for the ignition coil to go bad.

Timing there aint no fucking timeing, just match the stator ring mark to the mark on the central magnet.

Are you sure your ignition wire is good and making firm contact to the peg coming out of the coil? check your spark wire for continuity.

consult www.jawamoped.com which has technical drawings, and manuals on the various ignitions.

Ohmmeter indications

It is recommended to use an ohmmeter with 1.5 to 3 V in-feed.

Use ohmmeter with 1 kiloohm (10 kiloohms) range scale.

When checking semiconductor device, start with its internal connections.

To check the thyristor trigger circuit, measure the resistance between the

outlets I and 1, and repeat the measuring after interchanging the

measuring ends (i.e. reversing the fed-in voltage polarity). The measured

resistance must be different in both instances. The semiconductor device

is unequivocally defective if the resistance measured in both instances

nears 0 or ∞ . During the measuring between points G and 1 (and also

when interchanging the measuring ends) the indication in both instances

must be ∞. If a certain deviation is measured in one direction (+ to G),

the thyristor has a leakage which represents a defective condition. With a

faultless semiconductor device, the measurements in both directions

between the points G—I and 1—15 must indicate ∞. With some

measuring instruments (with a higher response of the measuring system),

it is possible to find within the 10 kiloohm range any defect of parts

between the points G and 15. When connecting the measuring points so

that the positive pole is to G, the instrument will show a deflection but the

pointer will return to ∞ after a brief interval. When interchanging the

measuring ends (points), the instrument indicates ∞ resistance. If the

capacitor C is shorted, the first measuring will show a resistance of

constant value. In the case of a short-circuit of the diode, the phenomenon

of the first measuring is bound to appear also after the interchange of the

points. It goes without saying that in the case of the interruption of D or

C , ∞ would be measured in both directions. We should like to point out

that with the phenomenon accompanying the first measuring, the

capacitor becomes charged to the voltage of the measuring instrument and

the check can be repeated only after the spontaneous discharging of this

capacitor which might take several minutes up to an hour.

A faultless ignition pole should give an ohmmeter reading of about 220 ±

10 ohms between pole core, vehicle frame (ground) and pole outlet (red

lead)

A faultless pulse-forming coil should give an ohmmeter reading of about

17 ± 1 ohms between the stator carrier and its outlet (yellow lead).

The resistance between the terminals 1 and 15 must be less than 1 ohm.

The resistance between the terminal 15 and the H.T. outlet should be

about 6,000 ohms. A defect can be ascertained unequivocally by this

measuring only in the case of an interruption of the circuit — the

measuring instrument indicates ∞ (infinite resistance).

Defects of the ignition coil are rare and therefore it is recommended to

check before its renewal the condition of the connecting leads and

terminals.

Replace the H.T. coil only with an original coil,
