Inspection Of Ignition Coils; Inspection Of Pick Up Coil (Crank Position Sensor); Inspection Of Pick Up Coil Air Gap - TOHATSU TLDI MD 115A SERIES Service Manual

7) Inspection of Ignition Coils

1. Remove ignition coil coupler.
2. Measure ignition coil resistance. Replace if other than
specified value.
This test can be made without removing parts.
Ignition Coil Resistance :
Primary Side :
Secondary Side : Between c and d 10.8 - 16.2 kΩ
3. Install plug cap onto high tension cord by twisting
clockwise.
4. Connect plug cap to spark plug.
8) Inspection of Pick Up Coil
(Crank Position Sebsor)
Remove oil tank 1 installation bolt 2 (upper one) and
1.
move oil tank a little.
2. Disconnect pick up coil 3 connector.
3. Measure resistance between terminals.
Replace pick up coil if the resistance is out of specified
range.
Resistance between Terminals : @20˚C (68 ˚F)
400 - 600 Ω

9) Inspection of Pick Up Coil Air Gap

Measure air gap a between pick up coil 1 and flywheel
1.
2.
Adjust air gap if out of specified range.
Air Gap a :
0.5 - 0.9 mm (0.020 - 0.035 in)
TLDI 115A 2007
Between a and b 0.4 - 0.6 Ω
(6.8 - 10.2 kΩ without plug cap)
