Wire the starter solenoid
Route the short heavy orange cable from the positive side of the battery to the front post of the
starter solenoid. Fit an 8mm yellow ring terminal and a red heat shrink tag to each of 2 lengths
of 10 gauge wire (shown above as light blue) and route one wire to the red pin in the regulator
plug and the other wire from the front post to the main bus 15A circuit breaker: pass the wire
through the right hand cable collar in the firewall and leave 300mm free inside the cabin for
fitting to Connector
C .
Fit a red female spade connector and a red heat shrink tag to 2 x 1m lengths of 16 gauge wire
(shown above as purple) and route one wire from the left-hand middle connector on the
solenoid to the starter button and one wire from the right-hand middle connector to the starter
pilot light - pass both wires through the right hand cable collar in the firewall and leave
300mm free inside the cabin for fitting to Connector
B .
The large and small spade terminals on the front post of the starter solenoid are not used.
Connect the starter motor
Earth the starter motor by fitting the long heavy orange cable under the top bolt that holds the
front of the starter motor housing in place – this provides maximum current to the starter unit.
Loosen both starter bolts slightly and then remove the top bolt and fit the cable under it.
Apply a drop of Loctite and retighten both bolts firmly. Route both orange cables back along
the top right engine mount strut.
The positive cable (the one that goes inside the starter motor) can be fitted to the rear post of
the starter solenoid and the earth cable can be fitted to the negative side of the battery.
Wire the firewall earth tag
The following 3 x 10 gauge wires are fitted to yellow 6mm ring terminals with black heat
shrink tags and connected to the firewall earth tag with a single AN3-5A bolt and Nyloc nut:
1. The negative wire from the black pin in the regulator plug;
2. The negative wire to the earth bus - pass this wire through the right hand cable collar
in the firewall and leave 300mm free inside the cabin for later fitting to Connector
C ;
3. The negative wire to the negative post of the battery. Do not connect this wire to the
battery at this time.
