# Solutions for Forklift Failure to Start

First, open the engine hood, pull out the central high-voltage wire from the distributor, place the ignition switch 6 to 7 millimeters away from the cylinder block, rotate the crankshaft, and check the electric spark produced by the high-voltage wire. If there is no spark, then there is a short circuit or open circuit in the low-voltage circuit, or a fault in the ignition coil and the central high-voltage wire. The contacts can be opened and closed alternately, and the pointer reading of the ammeter can be observed. If the ammeter shows a discharge of 3 to 5 A and swings intermittently, it indicates that the low-voltage circuit is good and the high-voltage circuit has a fault; if the ammeter pointer does not swing, it indicates that the low-voltage circuit is open; if the ammeter discharges a large current, it indicates that there is a ground fault in the low-voltage circuit. If the spark is too strong and produces a blue-white spark, it indicates that the low-voltage circuit and the ignition coil are good, and the fault lies in the high-voltage circuit of the distributor and the spark plug. Remove the high-voltage wire end from the upper end of the spark plug, shake the crankshaft and test the body. If there is no spark, check the ignition timing, distributor cap, and high-voltage branch wires for leakage; if there is a spark, check the ignition timing and the working condition of the spark plug.
