Cagiva Mito 125 How to test spark plug with multimeter to see if is it is good or bad

 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.

Cagiva Mito 125 regulator and charging system testing .


Need a multimeter try here 


need a new regulator rectifier try here 


need generator alternator try here 



First ill show a quick test on diodes inside you regulator rectifier .

You are just checking current flow through the regulators diodes in forward and reverse bias.

Cagiva Mito 125 regulator and charging system testing .

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 



Cagiva Mito 125 regulator and charging system testing .

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 



 

Cagiva Mito 125 regulator and charging system testing .

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

Cagiva Mito 125 regulator and charging system testing .

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

That is a quick test the rest of images that follow show tests from Cagiva Mito workshop manual
