User manual SWISHER ZT2560 REPAIR MANUAL

[. . . ] Try to crank, using the ignition switch. If engine cranks, the fuse or the fuse holder, or related wiring is defective somewhere back to the solenoid. TEST #4 If engine did not crank in test #3, make sure the drive controls are in neutral position. This time move the jumper wire attached to the positive terminal of the battery, to the green wire on S terminal of the ignition switch. If all components in the circuit are working, the engine should crank. [. . . ] The meter should be on zero with no weight on the seat. Pulling the seat down should open the circuit. 3 IF PTO CLUTCH WILL NOT ENGAGE Apply a negative ground to this terminal Apply 12 volts to this terminal. Clutch should activate, if it doesn't, clutch is defective. If clutch checks OK, use a voltmeter to measure if there is 12 volts at the brown wire's terminal. First turn ignition switch to the ON position but don't start the engine. For the first test put the negative probe on a good ground, not on the white wire's terminal in the plug. If no voltage is measured, move on to next test. With the PTO switch ON there should be continuity between these two connectors, if not, replace switch. If switch tested good, check wires and connectors back to ignition switch and back to clutch plug. If all checked good in the two previous tests, the problem may now be a poor ground on the white wire in the clutch plug. Check by testing for continuity to ground or check for voltage between the two terminals HOUR METER NOT OPERATING Hour meter has a positive and a negative post. Power is supplied from the ignition switch. Green wire from hour meter is grounded by the oil pressure switch, therefore only has a ground when the engine is running. 4 WIRE IDENTIFICATION AT SWITCHES 3623 IGNITION SWITCH One gray wire goes to the PTO switch and the other goes to the hour meter Green wire goes to PTO switch One black wire goes to PTO switch and the other goes to the engine plug Red wire goes to fuse and on to battery positive at the solenoid terminal. One white wire goes to clutch and other one goes to ground. STARTER SOLENOID Green wire goes to neutral switches and on to the ignition switch. Green wire with orange stripe goes to the ground. Heavy red cable goes to the positive post of the battery. PTO SWITCH PLUG Black wire goes to the ignition switch. Green wire goes to the neutral switches. Gray wire goes to the ignition switch. Brown wire goes to the clutch. 5 WIRING HARNESS TO ENGINE PLUG CONNECTION Gray wire goes to carburetor fuel solenoid Green wire goes to oil pressure switch Black wire goes to engine ignition module Red wire goes to engine charging system Green wire goes to hour meter Red wire goes to terminal on solenoid with the positive battery cable. Black wire goes to the ignition switch. Gray wire goes to hour meter WIRING HARNESS PLUG TO ENGINE Gray wire goes to hour meter Red wire goes to terminal on solenoid with the positive battery cable. Green wire goes to hour meter Black wire goes to the ignition switch. 6 BATTERY CHARGING SYSTEM Voltage Regulator Red wire goes to the engine plug and then on to the positive terminal of the solenoid to keep the battery charged. Easiest way to check if the charging is taking place is to measure the DC voltage of the battery before you start the engine. Measure the voltage at the battery with the engine running. The voltage should be at least one volt higher right after the engine is started. This voltage will drop a little as the battery gets recharged. To test alternator before it goes to the regulator, unplug the yellow connector and measure the AC voltage across the the two gray wires inside this connector. There should be at least 20 volts AC. CARBURETOR FUEL SOLENOID Black wire goes to engine ground. Gray wire goes to the engine plug, then on to the ignition switch where it receives power to activate the fuel shut off valve. Fuel shut off solenoid is a Briggs part and is available through them only. 7 DRIVE CONTROL ADJUSTMENTS LEFT SIDE SHOWN Control plate shown in neutral position Start your adjustments by putting the drive control arms in the neutral position. Remove the linkage from the control plate at the Eaton hydro by removing the cotter pin and washer on the under side. By moving the control plate forward and backwards by hand you can easily find the neutral position on the hydro. [. . . ] As the outer cable moves forward, the brake will become tighter. 10 DECK LIFTING SYSTEM Three rocker arms are activated by the deck lift handle. It drops straight below to the deck. This center rocker arm lifts the front center of the deck. It also drops through the lower frame but is directed by two pulleys under the mower frame to the front of the deck. The deck lift system has two springs to assist in raising the deck. The ease of lifting the deck can be adjusted by tightening this nut equally on each spring. The guide pulley for the front center deck lift cable. [. . . ]
