Pulled out some more interior fittings and cleaned the transmission tunnel of the insulation or sound proofing sheets. Engine dosen’t turn over, starter solenoid clicks – pinion gear engages with flywheel, but starter motor does not turn. When jump started a faint whir of the starter motor and the belts and fan moves slowly. Unbolted and dewired Starter Motor and started cleaning outside casing with wire brush and petrol.
