Inspection Of Starter Solenoid; Inspection Of Oil Level Sensor; Inspection Of Oil Pump - TOHATSU MD 70-90C2 Service Manual

21) Inspection of Starter Solenoid

This test can be made without removing parts.
1. Connect tester lead wires to both terminal of starter
solenoid.
2. Connector green (G) lead wire to battery positive terminal.
3. Connector black (B) lead wire to battery negative terminal.
4. Check electrical conductivity between terminals of starter
solenoid. Replace if no conductivity.
5. Remove battery terminal from green (G) or black (B) lead
wire, and check there is no conductivity between starter
solenoid terminals. Replace if conductive.

22) Inspection of Oil Level Sensor

This test can be made without removing parts.
1. Check electrical conductivity between terminals of oil level
sensor.
Check oil level sensor if out of specified range.
To be non conductive if float is at position a.
To be conductive if float is at position b.

23) Inspection of Oil Pump

This test can be made without removing parts.
1. Measure resistance between terminals, and replace oil
pump if the resistance is out of specified range.
Resistance between terminals : @20˚C (68 ˚F)
1.84 - 2.08 Ω
