Its a very easy but useful test to make sure your spark plug is ok , you may need to clean the electrode to ensure you get a good reading but all you then have to do is set meter to read ohms and measure from the spark plug cap end to the electrode tip , and then from end to body to make sure no leakage to earth.

Get set up turn meter to ohms reading on dial and clean the electrode as below

Test between end of spark plug where HT lead cap fits and the tip of electrode the reading is very low only 1.2 ohms

on a dirty part of electrode the reading goes wild and eventually read 188.9 ohms so very bad and to avoid this clean electrode tip

Next test from spark plug cap end to the body to make sure no earth leakage your meter should read OL which is a good reading as it signals no leakage to earth via the body.

connect + lead of multimeter to further left connector pin 
and common lead to 2nd pin from left you should get a voltage reading of around 0.6 
here i get 0.52 which is ok

then test 3rd pin from left it should give same reading

now connect common lead of multimeter to left pin and + lead 
of meter to the second pin from left you should get OL telling you no 
current is flowing as it should be.

Now test with + lead of meter to third pin from left and same OL
no current flow

now connect common lead to the further right hand side 
and + lead to second from left you should see 0.6v i get 0.52 which is ok

move red + lead to thurd pin from left and should get 0.6v again i get 0.506 which is ok

Switch + lead to further right pin and touch blue to second and 
third pins and you should get 0L no current flowing

Cagiva Mito starter motor post







I am going to collect info here on Refurbing starter motors for the Cagiva Mito 125

I was hoping to do a full rebuild on this on but all it took was a bit of oil on the bearings and a good clean out and re-lube where needed .


But its quite easy to change the brushes and bearing on these stater motors and can save a lot of money .

Getting in is easy just three PH1 screws

here you see the brushes holder plate i cannot find these to but if anyone know let me
know and ill link to it .  i use sizes 5mm wide 8mm high 15mm long 

Cagiva Mito starter motor post

here i am undoing the Brushes spring clip 

Cagiva Mito starter motor post

one you undo the main positive side brushes you can remove plate 

Cagiva Mito starter motor post

here are the positive side brushes the current  goes thought the connector on side of 
starter then through the field windings and then into the armature via the brushes 
then out again via the opposite side brushes 

Cagiva Mito starter motor post

the negative side brushes are  on the plate
and although it would be easy to change plate fiding them are hard 
i usually ......

Cagiva Mito starter motor post


Cut the old one off at spade connector then grind connector flat 
clean surfaces and re-solder the new brushes to this connector 
i did not have to do it this time but i will in the future .  

Cagiva Mito starter motor post

To change the Positive side brushes you will need to remove armature and winding
undo all the securing screws


Cagiva Mito starter motor post

remove drive gear retaining clip and gear 

Cagiva Mito starter motor post

  armature will come out and then you can access the brushes
 connector you need to clean and flux and then solder in new brushes
                       DONT FORGET THE INSULATION
                 
                                   
that is all i have now ill update this when i do a full stater motor refurb and solder in new brushes but have a go its quite easy .


Here on Ebay UK are some brushes i use


and here on Ebay UK are starter motors for sale Used .
