NOTE; 12v is loosely termed as battery voltage - easier to wright multiple times

If it hasn't got a solenoid on the starter then there will be a standalone one
follow the battery pos+ cable till you find were its mounted and give it a tap and see if it starts.
if not-
If you have a multimeter check if you have 12 volts to the small wire on the solenoid when cranking , there should be 4 wires to the solenoid 2 x battery pos + power in and out.
2 x small wire 1 x exciter 12v from key which pulls in the solenoid allowing the battery pos + to "flow" through the solenoid when cranking.
1 X small wire to earth or battery neg - .
Note some standalone solenoids are earthed through the mounting and will only have 1 x small wire = exiter wire 12v from key

if you have 12v to exiter wire then you should get 12v coming out of solenoid to starter motor .
if not then solenoid is U/S and replace .
If you are getting less than 12v to exiter wire then you can fit a relay in line to boost the voltage .
If you are getting no voltage to exiter wire you will need to back trace exiter wire to find out ware you are loosing power.

if you have 12v coming out of solenoid then remove starter and bench test by neg -jumper cable to body of starter and pos + jumper cable to pos + lead pole
Note if the starter is good it will jump when it spins.
You need to watch the sprocket at the end to make sure it throws out and spins as if it only does one its U/S



Hope this helps
